Ocean Werx

nicest DIY i've ever seen.

cool!!!

I believe most skimmer designs are around the same. BK, ASM, Euroreef, all look similar to me. Beckett skimmers too.

In my opinion, it is always better to isolate one pump for one beckett injector. if one pump fails, the beckett injector will still be working.

As mentioned, everything can be customised.

Zorden: everything can be customised upon request. Regards Ocean Werx

Thanks guys!! We will try to improve our workmanship.

Hi all, Actually PVC welding is not the most secure form of joints for acrylic. It is not actually recommended by welding companies. But we use it as a last round of defence. For our joints, there is more than just PVC welding, trade secret. All Ocean Werx product comes with one year warranty. Just send in the warranty card and we will validate the warranty. Regards Ocean Werx

Acidjazz, you are RIGHT!! running two sets of single beckett skimmer is definitely better than one set of dual beckett. (if all the skimmers are of the same size). However, not many pple have the space like Coral Farm. Most pple find a 4ft skimmer already an eyesore, needless to say about TWO 4ft skimmers. Blueheaven, beckett skimmers are one of the most reliable protein skimmers. but as you've mentioned, skimmer 10%, husbandry 90%. All skimmers (deltec, h&s, beckett, blah blah blah), as powerful as they may seem, it is still very important that the user / reefer maintain good husbandry.

Calciumreef, Not really true, its actually quite easy to clean. just run a cloth through the downpipes and it will be done. of cos, we are not talking bout coraline algae. that's gonna be a big headache.

where did you buy the pump from? if you got it from Bio Ocean, you can come anytime for replacement.

Not too sure if you are refering to us. Aquarama Fluidised Reactor We still have some in our shop.

for rio 20hf, 32inches height is too tall. in fact, even for a 2ft tall, it is "just ok". if possible, we will still recommend a stronger pump like quietone 4000 high head. and at 32inches height, the skimmer most likely have to be installed out-sump. the head loss will be too much for the rio 20HF. Regards Ocean Werx

The deltec auto-cleaner is to clean the inside of the riser neck so that the "scum" will be removed. the "scum" has negative effect of the skimming. too much "scum" and the foam will not be able to push up into the collection cut.

Zorden, it takes hours, perhaps days for skimmate to dry up and thicken. you are right to say that the new skimmate will mix with the old ones. as i've mentioned before, only minimal will retreat back into the tank. most of the "scum" will remain at the top layer of the foaming. unless the collection cup is filled up and left to run for months, there shouldn't be significant effect on the tank parameters. I cannot calculate the amount of concentration of old skimmate and new skimmate, but from our understanding, it shouldn't differ much. I cannot confirm the exact amount of skimmate that will retard back into the tank. But I CAN assure that the tank condition will not be any worse than if the skimmer is not skimming. We have already concluded that our beckett skimmers can be used in-conjunction with a auto-shut-off waste collector. I believe most who had shown interest in this thread do. When used together with a waste collector, the skimmer WILL NOT overflow. If the skimmer is left running (but not skimming) for weeks without anyone attending to it, the tank parameter will DEFINITELY worsen. Same thing applies for our skimmers, whereby our collectio cup is not air tight, tank condition will also worsen if left unattended for weeks. End of the day, even if one has the most expensive, sophisticated equipments, a reef tank might not survive if the owner practises ill-husbandry. It is good husbandry that decides the success / survivability of a good reef tank. We strongly advise that skimmers should be cleaned at least once a week. Regards Ocean Werx

shoelevy: thanks again. to add on to shoelevy's wonderful explanation, our beckett skimmer actually continue skimming when the waste collector fills up. It will continue to skim until the collection cup gets fill up. However, the air-tight version will only fill up the waste collector and thereafter totally stop skimming. zorden, even when the collection cup gets dry and more concentrated, it is still originally from your tank. perhaps, when the collection cup gets filled up, the new skimmate might mix with the "drier skimmate", however the level of concentration should be negligible. wouldn't have too much of effect on the tank condition. As mentioned, when collection cup fills up, the extracted skimmate will actually remain at the top layer of the foaming and only minimal will retreat back into the tank. It is definitely better than not skimming at all. blueheaven do you mean this? So it means that you CAN run an Ocean Werx skimmer using a waste collector if you want its flowback mechanism. while if you want the auto shutoff, you will need an airtight skimmer. Am I right? YES, different mechanism but same shutting down capability. We shall continue discussing on the air vent issue. If there are still any "blind" doubts about our design, please kindly give us a call at 6396 7783.

zorden as mentioned, it is totally safe. most of the pollutants will remain at the top layer of the foaming. only minimal will retard back into the tank, and it will be diluted within the skimmer before it reaches the tank. thanks for your compliment.

shoelevy + calciumreef thanks a million for the pic. it shows exactly what will happen when the waste collector is full and thereafter collection cup. The skimmate will simply flow back into the riser neck. Thanks again. If the user prefers wet skimming, the deflection ring will help to direct the foam into the collection cup. However, if the user prefers dry skimming, it can still be done by lowering the water level in the riser neck. The main purpose of the deflection ring is to direct / deflect the foam into the collection cup. I've seen a few beckett skimmers (inclusive of our old batches) that actually have foam build-up at the top of the riser neck but seems to constipate there. zorden + blueheaven When collection cup fills up, the extracted skimmate will actually remain at the top layer of the foaming and only minimal will retreat back into the tank. However, in the air-tight version, the skimmer totally stop skimming. All tank water that is pumped into the skimmer is being forced back into the sump / tank without any skimming at all. Skimmate is basically DOC and other pollutants that is extracted from the tank water. I don't really agree that it will further pollute the tank, skimmate is what should already be present in your tank if it is not properly extracted. Even if it flows back into your tank, it is where it belonged originally. Therefore, it will not release any additional pollutant into the tank. It will not aggravate the water condition. zero endless: which part are you agreeing to? I sincerely hope that you can clarify. Hi all, I hope I did not mix up the main issue here. We were mainly discussing on whether the auto shut-off waste collector can be used on our skimmers. The answer is YES. it will still work; 1) the auto shut-off waste collector fills up, 2) the ping pong shuts the waste collector, 3) the collection cup gets filled up, 4) extra skimmate simply overflows back into the riser neck of the skimmer. Pertaining to no. 4, shoelevy and calciumreef had already posted a clear pic the show how the skimmate will overflow back into the riser neck and not overflow out of the collection cup. Hhhmmm....Rex Ng, anything you wish to advise on? Thanks in advance. This thread is certainly open for discussion, but please don't claim "blind" things. Thanks everyone for your valuable inputs. Whao!! I LOVE THIS THREAD!!

Hi BH, the air vents will not help in anyway when the skimmer overskim. If you look carefully, the riser neck is shorter than the top of the collection cup. when the skimmer goes bonkers, the excessive skimmate will flow back into the riser neck and not out of the collection cup. therefore, a waste collector can be used in either air-tight or non air-tight skimmers. For the latter, the mechanism will be slightly different. but both the skimmate or your sump water will not overflow out of the skimmer. I hope you can understand my explanation. If otherwise, please feel free to ask any questions. Regards Ocean Werx

Hi Rex Ng, perhaps our 2yrs of experience in building skimmers is not as rich as your wonderful knowledge. would you kindly explain to us why you said that we copied our skimmers blindly? if otherwise, it may be unnecessary to post; "I think you must have copied the skimmer design with your eyes closed. Yes it may look different but it doesn't serve any purpose. You are only trying to make the skimmer look different." Perhaps, its just some misunderstanding. would you like to go through the full thread again and point out what I missed out in my explanation? Thank you. Regards Ocean Werx

Calcium Reef Exactly, the scenerio that I gave is with the use of an auto shut-off gadget. If there are still any doubts, please feel free to drop by BOA and we will show you a LIVE demostration here. hotlemond beckett nozzle design enables it to draw in tremendous amount of air. If air is only released thru the hose barb, there will more or less be a slight restriction the the air intake. Even though we use as big a hose barb as possible, we don't take chances, that's why we included the extra air vent. Basically, we at Ocean Werx don't copy designs blindly. Doesn't mean that other beckett skimmers are build air tight, we should build it air tight too. In fact, the time and resources used to add on extra grooves and deflection rings are more than that of a simple air tight design . If you guys remember, we used to design our skimmers air-tight too . http://www.sgreefclub.com/forum/index.php?...1071&hl=beckett But after some simple R n D, we decided to go against it.

oh my god, that's quite a negative scenerio. guess you've have not seen my post before posting this. as mentioned, the skimmate will simply overflow back into the riser neck and will not overflow out of the collection cup. let's pray that murphy will not come knocking at any reefer's door anytime soon.

Whao, that's quite a good friendly debate. Weisoon: yes you are right. with the vent holes on the collection cup cover, MarineMan will not be able to use the shut-off gadget correctly. As for the back pressure (if the collection cup cover is air-tight), it will be release thru the drain (gate valve) and will not have any ill effect on the pump. But with the vent holes, the shut-off gadget can still be used. Quite surprising right? We tested with our own skimmers with a shut-off gadget and this was what happened. 1) the auto shut-off waste collector fills up, 2) the ping pong shuts the waste collector, 3) the collection cup gets filled up, 4) extra skimmate simply overflows back into the riser neck of the skimmer. Calcium Reef: Thanks for pointing that out, I didn't know that aquaC manufactures auto shut off waste collectors. I'm quite sure aquaC skimmers also have vent holes on the collection cup cover, maybe they've changed their design and i've not noticed yet. Pretty cool self cleaning head. We are trying to make our skimmers self cleaning too but not with brushes. Originally, our skimmers did not come with the skimmate waste drip. Both skimmers in Bio Ocean Aquarix don't come with hose barb. But since consumers insisted that we should have it, we added it. Enjoy Reefing!!

Hi Guys, the above set is custom made for MarineMan. I've attached a picture below, of our BS2-608 Reaction Chamber: 8 inches Footprint: 30cm X 30cm Total Height: 60cm No. of Injectors: 2 Maximum Capacity: 2700ltr

Hi Sugi, thanks for the explanation. As mentioned, once the waste collection bottle is full, there will be back pressure right? Which means during that period of time, the skimmer will no longer produce skimmate isn't it? We are not a keen supporters of the waste collection bottle because we feel that for a skimmer to work to its optimum, it should be clean at least once a week, and not let the waste collection cup to fill up before washing it. So far, only beckett skimmers come with this auto shut off collection cup. have you guys ever wondered why reputable brands like Deltec and H&S and even AquaC don't come with this gadget? However, having the auto shut off gadget will come in handy when the user do not know how to tune the skimmer properly. No offences meant, just want to explain the design of our skimmers. If required, we can still make it air-tight.
