  1. Nero 5 Aqua Illumination New Wavemaker

    Thanks bros for the pulse setting. The 0.25 Sec works. The increment is 0.25. Thanks so much!!! Sent from Singapore Reef Club mobile app
  2. Nero 5 Aqua Illumination New Wavemaker

    Thanks for all the advice. It is almost safe to say it is not a replacement of the MP10 but if you want smartphone connect without apex or the ecotech hub this is a good buy. Sent from Singapore Reef Club mobile app
  3. Nero 5 Aqua Illumination New Wavemaker

    Thanks for the maths! Mine is a 40cm by 40cm nanotank. Lol. Some minor edits to the above review. I think the connection is via Bluetooth only and not WiFi. Unlike the AI Prime light. When I turned off the Bluetooth on my phone it alerted me to turn it on. Sent from Singapore Reef Club mobile app
  4. This is a short review as further extensive tests are required. I got this as a replacement for the Nanostream Tunze 6040 (which is working fine). Before that, I have the iconic EcoTech MP10 which broke down 2 years ago and was beyond repair. Retail price for Nero 5 is SGD390. The Good It is small like a pluck. The waves are powerful (google for the specs) The control unit looks elegant. It just works It is silent. Setting up various modes (random, constant, feed time) is a breeze. It looks amazingly high tech in a tank. Setup using Bluetooth is a walk in the park. iPhone and Android controllable. The Not So Good Unlike the AI Prime light interface on your phone which is near perfection, there is room for improvement. For example I can’t manually dial the speed and I have written to AI for advice. Unlike the Tunze 6040, i have no success in creating standing waves (yet). Unlike the Vortex and Tunze, you can’t see the wavemaker doing pulse mode. As in- it comes to a near stop and then speeds up again to create waves. Perhaps it is the design of the Nero 5’s rotating fins and you can’t see it in action but it is actually doing it. Although the physical control unit is beautiful, if Steve Jobs designs a wave maker and control unit, it will look like this (we all miss him), but the control using one button is a tad too minimalist. Press once for this , press a few seconds and hold and then see blinking light, red light, blue light and white light..., after a while you have no idea which is which. The instructions in the box is too minimalist and i think trying too hard to be Apple-ish. I think the software is still early and overtime it will improve. I like the flow as the corals are doing extremely well and to be fair, they were doing fine when I was using the Tunze. One more thing. If they can have tiny grills at the back of the wave maker to prevent sucking in anemone, it would be great. Summary It definitely passes the feature tests (fantastic flow, WiFi connected, Bluetooth connected) and it looks like a piece of space tech equipment in your tank. However, further improvement is required in terms of the software. If I recall, EchoTech has acquired Aqua Illumination or they have a joint collaboration so they know how to make a great wavemaker. The reason why I did not get the MP10 is that it juts out of the tank (I know -no heat inside the tank) and not easily controlled by smartphone unless you buy another expensive controller (I think). The Nero 5 is controllable by smartphone the moment you unbox. Anyone who has similar experiences or differing views, please post and compare useability notes. I also need help creating standing waves (for visual only, I think the fishes and corals don’t care lol). Sent from Singapore Reef Club mobile app
  5. Zeovit is a famous brand which propagate a low nutrient system. Google it. Zeolites is a kind of porous stones. You are right. But you can get Seachem Zeolites which I think is cheaper Sent from Singapore Reef Club mobile app
  6. Upgrading my tank

    Hi I just upgraded my tank from 10g to 14g. I lost two creatures due to overconfidence as I threw away the old sand as it was dirty. I think the trick is to transfer everything and have zeolites ready. Zeolites turns out to be the best emergency ammonia absorber. So even if the new tank is not fully recycled the zeolites will kick in. And stock up some good activated carbon and Prime. The lesson i learned is that somehow the bacteria level is based on the occupants. Say you have lots of marine pure in a tank which far exceeds the tank size. The amount of good bacteria (there is a science term which I forgot) will not be more than the existing bioload. In other words the bacteria in all your existing rock, sand, floss and marine pure is about the same even if you have a few more blocks of marine pure. When you change the tank some bacteria will die off and hence the new tank syndrome. So have the zeolites, Prime, spare water change ready. Sent from Singapore Reef Club mobile app

  10. For the record, no fish is harmed. More importantly this is a controlled experiment -DO NOT EVER set up a marine tank without proper cycling. Thirdly, I use some experimental enzyme that consumes ammonia and nitrate. The purpose of this experiment is, at least to me, learn about nitrogen cycle and how far we can use the latest "bacteria in a bottle": method to cycle the tank. But this is not a "pure" test as I have transferred some porous medium full of bacteria from my lab tank. Call me a wimp I just cant let the fish suffer ammonia poisoning. Here goes: Lots of chaetos I bought from a reefer bro Whole bottle of API Quick Start Small packet of Chemipure Marine 2 small pieces of floss with bacteria from main tank 10 small round pieces of porous bio filter My experimental enzyme 0.1 ml One Chromis codenamed Laika. In honor of the Russian space dog, perhaps the first space traveling creature (space nerds will get it) Results: I managed to get zero ammonia the next day and Laika is very much alive. Observation: So ALL the senior reefers who tell us newbies TO HAVE PATIENCE and not bio-overload the tank is true. Think about it. With all the bacteria tech and just one fish, we can "theoretically" skip the cycling and keep one fish alive. In other words, if we dont add the fishes in haste, some "carry over" bacteria can effectively or perhaps temporarily nullify ammonia poisoning (with lots of caveats.) Again I did not do a "pure" test. Future testing parameters: A) use the API Quick Start alone without bringing over the bacteria from the main tank. Just use the old bacteria without enzyme and without QuickStart. C) just use the enzyme. So further tests can be done. And a single small Chromis bio load is very little and Chromis is hardy by nature, so the experiment is a mild "success". In a marine tank, you still need to cycle the live rocks, sand and other medium like Marine Pure blocks. No running away from proper cycling. For reefers who laugh that this is a futile experiment and of course, it will work, yeah, but that is the joy of reefing, we test for possibilities. Laika is well and is back in the main tank.

  11. Thanks for all the great ideas! And I have Seachem Prime on standby. Sent from Singapore Reef Club mobile app
  12. Dear Reefers, We all have experienced the following situations before (this is written in a jest manner so take this with a pinch of ..salt*): While tampering with the filter medium, you saw some unsightly dirty filter floss or sponge, and you think to yourself, "hmmmm I can just clean it to reduce Nitrate build up, I know there is good bacteria inside but hey, I have plenty of ammonia-converting bacteria in the live rock, sand, Marine Pure, floss, so cleaning THIS PIECE wont make any difference". You washed the floss and replaced it back in the tank and the next morning, the corals were not opening up and OMG you have a sudden Ammonia Spike. Step 1. Water Change. Yeah thats what everyone tells you. And you look at the RODI Container and realize you did not top up the RODI water tank! Or WHEW! you got enough RODI water and you looked at the watch and you need to go back to the office.. like NOW. Step. 2. Hey I got Anti-Ammonia additive or water conditioner or some leftover additives that looks promising. And you poured it inside the tank hoping for some miracle. And at the back of your mind, you were told that adding anti-chlorine may give false-positive when you do the Ammonia test later but this is an EMERGENCY, never mind that. This may work. Step 3. Go to office. But worried the whole day. Step 4. You come back home and see your favorite fish lying on its side, the shrimps are all dead (they are more sensitive to ammonia poisoning), the corals are closed up and your beloved tank has a mini-crash! Over the years, I have like countless bottles of Anti-Chlorine, ATM Outbreak, emergency activated carbon, Poly membrane etc, Prime but what REALLY WORKS TO BUY TIME? I found out that Zeolites is the reliable FIRST AIDER. Put it in a bag and dump it in the sump/Canister/ back chamber/reactor. It just works. Yes you still have to change water later, you still have to slap yourself for taking that piece of "dirt" out but on several occasions, it has saved my tank. So my 2 cents lesson is stock up on a S$10 bottle of Zeolites. You dont need Zeovit high end stuff. Just some Zeolites - it is a break glass during emergency thing to have at home. Wish I had known this earlier! Please share your Tank Crash Experiences and your Recovery Methods. (*I do not make light of the tank crash scenario - it is stressful and sad due to the death of your beloved pets.)
  13. Tesla Green Lab Tank - Enzyme powered

    My readings are 0 nitrate (even on high resolution kit red sea), 0 phosphate, alkalinity is 7, calcium is way too high at 600 but it could be an old test kit. So it is a low nutrient tank. I dosed redsea Nopox 2 ml daily now reducing to 1 ml daily. Has a micro refugium powered by chaetomax led, the chaeto is alive but not growing due to the low nutrients, and the minimax reactor is 80% zeolites and 20% biopellet. I pump the minimax reactor daily like the zeovit method. Weekly I dosed ATM Outbreak which is a bacterial source. In the canister I have 3 packets of activated carbon, deNitrate and Phosguard or phosban (can't remember). Plus my every 3 days dosing of 0.5ml proprietary enzyme. Yesterday added Redsea Reef Energy A+B. Water change 15-20% per week. Result is a low nutrient tank. Despite that a few micro thin strands of algae in my super thin sand bed which can be siphoned off easily. The next thing is how to do a low maintenance low nutrient tank. Auto water change. The challenge is not getting too many pipes and tanks and accessories as this is a Soho tank. I have a Rodi pump and using the thin hoses I can set up an auto change gig. Just have to unplug and change the direction of the hoses. Let's see if it is worth the effort. Sent from Singapore Reef Club mobile app
  14. Tesla Green Lab Tank - Enzyme powered

    Thanks bro for the feedback. It is tempting. The scientist I am working with is thinking of setting up a pure enzyme tank and let's be more ambitious and use the enzyme to cycle tank. Problem with my tank it is a display tank doubling up with some light product testing. I have tried even nano silver beads (another tech startup product for water putification) in the past. So the quick answer is yes I am as curious as you to find out what I can do with the enzyme and not likely this tank as it is SO HARD to reach zero for both nitrate and phosphate. First time after 4 years of reading. The good news is we are building a plant in batam to produce industrial ptoducts/RD Center. And yes, I want a test tank there. Cant wait.
