Long term Nitrate problem Hello, New to the site. I have had a 120 gal tank with a sump for a couple years.
It FWLR and some shrimp, starfish and a lobster. It has 100+ pounds of LR and a 3 to 4 inch sand bed. I only have five med to small fish in it right now. The sump has media filter, a nice skimmer and I just added 15 red mangrooves a few weeks ago.
I am having to do water changes every couple of weeks to keep my nitrates below 20.My goal is to get the nitrates to unmeasureable and possible move to a reef.
Here is what I have tried in the two years I have had the tank. (I know it is not supposed to be this hard)
1. Cut back number of feedings from 3 to 2 and have decreased the amount of food during feedings
2. Upgraded the Skimmer
3. Removed Bio Balls
4. Tried a Nitrate sponge
5. Tried a carbon filter
6. Tried Amquel plus
7.. Just added red mangrooves
What else can I try?
I am looking to upgrade my clean up crew. It looks like number of hermit crabs has decreased. My cleaner shrimp and cleaner star fish have disappeared in the last few weeks. I have 25 to 50 hermit crabs, one blood shrimp, choc star, purple lobster and one Mex turbo snail (Had 6 and down to one) What do I need to add? I hestitate to add snails because I think they may die due to my Nitrate problem
Thanks for the help,
