    Another possible cause: the Prizm skimmer is WAY WAY too small for a 4 2 2 ! I know its rated for up to 90G (I have one on my 20G nano) but that's just sales talk. The reaction chamber is tiny. On my 4 2 2 , I run a Kent Marine unit - rated for 300G, but nobody believes it of course.

    Upgrade the skimmer!

    Durso standpipe and hole in back of tank

    Durso's used in the overflow chamber. If you're not drilling (BTW, why are you drilling .. if this is a custom tank, then the manufacturer will drill and fix things up - you just check that there's no leak), you will need an overflow box.

    It looks like this:

    I think there's a thread in this forum about a DIY piece. Not sure where. Such a box is prone to lose siphon - when that happens .... get mops ready! To remedy that, some people attach an airline from the top of the overflow box to the venturi intake of a powerhead, so that air is sucked out. For details search:

    Just to share to everyone my experience in Harlequin Marine shop. Overheard a conversation between them and customer asking them how long for them to set up a reef tank. They replied, " Very fast! once tank is ready, will delivered to your place together with sand, live-rock , corals and fishes. will dump everything in at one go cause they hav no time to come back the 2nd time. THIS ARE THE SO CALL EXPERIENCE HOBBYIST. In my mind i think those people want u to came back fast to replace your dead corals and fishes. They make sure that they rip u not only 1 time but 2nd or 3rd. Fxxx up shop. Won't be going there anymore cause its a Black Shop.

    Actually, don't you think ALL LFS have this at the back of their minds? They set up shop to make money for a living. When times are bad, businesses don't give two hoots about ethics. And they are not hobbyists (hobbyists are not in it for the money, you see) - they are basically business people out to make a living - just like those of us here in this forum who may be employees ... also making a living ...

    Just remember - its always "buyers beware" whatever you buy and whichever shop you buy from ....

    Durso standpipe and hole in back of tank

    quix,

    My tank's bottom drilled. I'm not sure why it should be at the back - maybe someone else can help.

    I had a durso standpipe made - it is a modified one that you can find in the durso webpage. The one with the top that can be rotated to adjust the amount of air. However, I found it very difficult to adjust to be in sync with the return pump. Also, it wasn't as quiet as I would or thought it should be. In the end, I removed it and stuck two straws in and its almost absoluate quiet now - no more grugling or toilet flushing sound.

    just my experience .....

    BTW, why don;t you visit this site and see what this US reefer did to keep his overflow quiet:http://www.sparklingfloorservice.com/maintank.html

    Hey Rhun,

    You may not be ready for reefkeeping yet. Perhaps you may want to look up the reefkeeping links in the forums here ( and elsewhere too). Someone suggested your tank has not cycled (and it probably didn't).

    The hardware you have is not appropriate for reefkeeping - especially the canister filter. It will be a very efficient nitate factory. "Double tube light" sounds like normal output fluorescent - OK for fish - useless with corals.

    Why don't you read up more and examine your set up again before you spend anymore money on livestock? Lives are in your hands ....

    Taiwan Brand RO/DI Unit

    in Product Reviews

    Posted

    The RO/DI unit I refered to was selling in Taiwan. Its the cheapest unit under this brand ("chan" something - forgotten). They have more fancy ones. There are several companies in Taiwan manufacturing RO/DI units. I've also seen cheaper ones (around S$300 and usually without a pump) but I doubt the build quality.

    If you like US ones, check this out:

    www.airwaterice.com

    Seems popular in the US. Good price but the freight (int'l handling US$25, USPS freight US$115, UPS US$150) will wipe out the 'good price'.

    Adding new fish

    in FOWLR (Fish-only with Live-rock)

    Posted

    Good point. I've had the three tangs living together for about 9 mths now. No problems at all. Perhaps the tank is big enough (for now at least) so I wil add the powder blue if I can find a small one.

    Anyone know where a small powder blue is available?

    I've decided to drop the bannerfish in case I strike Toto and decide to add corals later...

    thanks

    Adding new fish

    in FOWLR (Fish-only with Live-rock)

    Posted

    Hi. Need feedback on possible new fish to a FOWLR tank.

    The tank is a 4 footer, about 320 litres. Currently contain live rock (with lots of button polyps), 1 yellow tang, 1 regal blue tang, 1 red sea sailfin tang, 1 foxface, 1 maroon clown and 2 hermit crabs, all living happily together. Light is Arcadia 60 watts NO (half daylight, half actinic).

    Thinking of adding a powder blue tang and a bannerfish.

    Questions:

    1) I was advised that the powder blue may be very aggresive towards the other tangs. True?

    2) The bannerfish may be difficult to feed commercial food and may dine on my button polyps. True?

    Appreciate any comments.

    thanks

    Taiwan Brand RO/DI Unit

    Hi Platax,

    As I understand (and verified from information available in the net), if tap water is passed though a DI unit directly, the effectiveness of the resin will be reduced very very quickly. If very pure water (like those passed through a good RO membrane) is passed though a DI unit, the lifespan of the resin is definitely much longer. Similarly, if tap water is not filtered properly before passing through an RO membrane, expect to replace the expensive membrane very soon.

    The sale guy demonstrated the effectiveness of the RO/DI unit with a TDS meter. The TDS of the unfiltered water was 76ppm. The TDS of the filtered water at the end was just 2 ppm. That's about 98% purity, in line with good RO unit performance. I drank the water too - tastes good!

    The guy didn't have a phosphate test kit so I don't know how good the reading is.

    Hi,

    Anyone out there have any experience with Taiwanese brand RO/DI units? I came across a 6-stage 50gph unit costing about S$500. They are also offering one set of filters (without the RO membrane) free.

    The RO membrane label claimed a size of just 0.001 micron. Could this be true? I am not aware of this size.

    Thanks

    Auto water top-off system

    in DIY Forum

    Ian

    Thanks for the link. No wonder a search I did revealed nothing. I was searching auto water topoff system ....

    It looks good. But I have a phobia about all these electrical stuff in the water. I would prefer a non-electricity driven one like the nurce or use a device like that found in toilet cistern. The float switch method will be my last choice. Right now I am using a simple drip. Still need to top up manually, but I make fewer trips from pail to sump. Unfortunately, it doesn't work for my 2 footer without a sump.

    Thanks
