macros algea will help if you can get some in there maybe put some in a basket up the top so wont be seen. how often do you clean change your filter media and what media is in there as that could be an issue?

You can try another test kit like salifert or red sea. In my experience api test kits always read high.

why mess with it? if everything is thriving and your corals are growing, just stay the course and don't change. if you do want to try and lower those trates, id clean out the entire back section. take out everything back there, clean it out real good, also look for detritus under and behind your rockwork. rinse the chemisorb off in old tank water when you are doing your pwc's. also the thing ive noticed is if you were doing bi-weekly water changes and switched to weekly, it takes awhile for the benefits of weekly changes to appear. just keep at it

not a expert but having similar issue. 29g ..water in check except my nitrates between 20 and 40 with my api test kit. I was always told it reads high especially the nitrate kit , everything alive in my tank seems happy besides my blenny who is stil getting used to having a pair of clowns with him now.

ive been keeping up on water changes from day 1 and really have a problem getting nitrate lower ...if you consider it a problem which i consider it more of a personal goal now since everyone in the tank seems happy and doing great.

my 29g isnt a biocube so my new project is filtration and such...running a HOB which I clean weekly and honestly dont think its the reason for higher nitrates like most things ive read , I also use distilled water for everything. I think its more of a case of newbie overfeeding and think I need some macro algae like you have had mentioned to you also

I have also been using microbe lift special blend to help boost my bio-filter and keeping water clean , it mentions helping with nitrates also ... haven't been using long enough to see if it will help that much.... I am in process of getting more rock for decoration and with seeding will help more with my bio-filter and getting some macro algae but i want some I can use to decorate with since Im FOWLR and have no corals ... will help with the eye candy of the tank also

Hi! Thanks for replying. ..sounds like you and I are in the same boat. ..I am fairly new also!! Yea all of my fish...urchin...and anemone are thriving and doing great....I too think I was over feeding....so I cut down to every other day...I feed only one kind of food which is Rods fish only blend....like you I have no corals yet....I plan on getting some someday...but I want to be much more experienced first....maybe everyone is right...the API kit tests high for nitrates. ......I do a 10% water chg every other week....on my normal schedule. ...but was doing them more often trying to get the nitrates down....but back to my normal schedule for now sence everything is doing good...sence we have a similar situation plz keep me posted on how your tank is doing! 8)

I just wanted to add for all of you to up the water change from 10% to 25% weekly and also with saltwater you should always feed your fish every other day and not very much also I agree that cleaning out the entire back section could also help. Cleaning the floss every 2 weeks helps as well I don't like to leave the dirty floss in too long as it leaches nitrates back into your tank.
The best advice is keep it clean and always replenish your cleanup crew they are important!!

I guess I missed this in my first read! But I recommend you doing more research on using distilled water as I have found that it is not as benifishial as simple reverse osmosis water which carries some minerals that are helpful to your tanks

You seem to know a great deal about Salt Water Tanks. I'm not questioning your knowledge but could you provide me some resource information about feeding every other day to keep Nitrates down?

I run a 300 gallon Reef & I'm having to do 100+ gallon water changes every week or two to keep my NO3 to 0.5ppm. By the second week the Nitrates climb to between 15-20ppm.

Needless to say I go through a lot of RO water and salt I make myself... Thank You!
