Nitrate Off The Scale

[shubzz]

Hi all

I have a 200ltr tank with 30kg of live rock a fluval 305 filter. I have 1 porky puffer, 1 dog face, 2 cardinals, 1 scooter blenny, 1 bird nosed wrasse, 1 tassled file fish, 1 green mandrin, 1 wet morella and a red knobbed star fish.

all has been fine BUT my nitrate levels are off the scale. I've just done a 40% water change TWICE and my nitrate is still off the scale showing +100mg. I will continue to do the water changes but any tips

I have just bought a 450ltr tank with a sump so a new home and new water beckons but I'd still like to sort this out as I'm certain it must be causing my fish some stress???

ta very much

Hi

you might want to think about starting a journal, list all the equipment your currently using as well as your stock, corals etc.

You say your using a fluval 305, whats in it and whats your housekeeping like? Ext filters can be nitrate factories themselves.

Have you had a 2nd opinion? Take some water to your LFS to test and see what they make of it.

As above filter media can become nitrate factories over time.

Can;t talk from experience with the filter media but thats well advertised on various posts I;ve read in the past. I also suffered from nitrate but aquired a cheap submersible light for about £6 and got some cheato and now my nitrate is 0 and has remained so for a few months

Also I can recommend NP Bio Pellets, I had nitrate problems, some of these in a fluidised reactor and NO3 and PO4 now fine although it does take a little while to balance it properly.

You have two very heavy waste fish in your tank and if they are near adult size in a tank of 250l they will have outgrown it - wonderful to hear that they are getting a lovely new home, cant wait to see photos However, they are still going to be heavy waste producers, you are skimming? I would run both a nitrate and phosphate reactor with such adorable fish

Those are some HEAVY waste producing fish. A huge bioload. To feed them right, you will probably have a nitrate problem in that small of a tank. Go ahead and move them to the larger tank. You have any algae trouble? If you don't have a skimmer, invest in one.
