SRC Member Clement Chen Posted August 9, 2020 SRC Member Share Posted August 9, 2020 Whats ur setup like? Any skimmer, chaeto, ats? If have skimmer can do carbon dosing. But go slow dont suddenly drop ur nutrients too much Quote Clem's Clam Corner (Decommed) 60cm x 40cm x 30cm Tank Nano tank reboot v2.0 Link to comment Share on other sites More sharing options...
Calvinmingming Posted August 9, 2020 Author Share Posted August 9, 2020 Hi have skimmer n also start chaeto but still very high Quote Link to comment Share on other sites More sharing options...
SRC Member Clement Chen Posted August 9, 2020 SRC Member Share Posted August 9, 2020 Can try redsea nopox or aquaforest nitrophos minus or just vinegar. But do read up first and start slow Quote Clem's Clam Corner (Decommed) 60cm x 40cm x 30cm Tank Nano tank reboot v2.0 Link to comment Share on other sites More sharing options...

SRC Member Clement Chen Posted August 9, 2020 SRC Member Share Posted August 9, 2020 Maybe u wanna try getting a salifert nitrate test kit. It is more reliable. And yes carbon dosing is safe for fishes and corals. 1 Quote Clem's Clam Corner (Decommed) 60cm x 40cm x 30cm Tank Nano tank reboot v2.0 Link to comment Share on other sites More sharing options...
SRC Member R0B Posted August 9, 2020 SRC Member Share Posted August 9, 2020 First I suggest you retest to make sure your result is accurate. API test kits are notoriously inaccurate. Once result is confirmed start to do a series of water changes to get the value down. 20 or 30% at a time if possible. You may need to do two or even three changes over the course of a week or 10 days.After doing the water changes you need to address the possible causes... Look at inital water source. Move to RODI where possible. Look at soures of nitrate being generated, are you adding in too much food or have too many fish? It could also come from an accumulation of waste. So make sure you are cleaning out filter socks regularily, cleaning sand bed, and cleaning out sump. After addressing possible causes, you need to think about nitrate management. Take a good look at your mechanical and biological filtration and make sure it is adequate. Does the tank have enough flow to get the detritus suspended, is the skimmer turned in and size appropriately. Are you on top of your regular water changes and cleaning.. After mechanical look at your biological filtration. You have some macro algea so that should start growing and absorbing that undesirable nutrients. Just remember to harvest it regularily. Also you can give your biological filration a boost by adding in bacteria and additonal bio media if you don't already have (especially if you are running bare bottom tank). Carbon dosing and/or adding bio pellets, or even going down the zeovit route are other options to boost the beneficial biological filtration of you tank. Anyways, Good luck. Hope this helps get your nitrates in check. Sent from Singapore Reef Club mobile app 1 1 Quote Link to comment Share on other sites More sharing options...
