TimB Posted December 16, 2012 Share Posted December 16, 2012 Hello everyone! I have recently tested the nitrate levels in one of my 6ft tanks and it is suprisingly high. It is stocked with 19 juvenile mbuna and filtered with a fluval 205 as well as a fluval 203 (canister filters). I do 20% waterchanges weekly as well. Fish are not overfed and eat most ofthe food before it reaches the bottom. Ammonia is 0ppm-0.25ppm, nitrite 0ppm and pH 8.2.Do you guys have any tips/methods for lowering nitrates??? Much apprieciated, Tim Link to comment Share on other sites More sharing options...
Jason130497 Posted December 16, 2012 Share Posted December 16, 2012 Larger water changes to get rid of the excess amount, so maybe 30% a week? Link to comment Share on other sites More sharing options...
TimB Posted December 16, 2012 Author Share Posted December 16, 2012 Cheers mate, I will start to increase my waterchange volume. Link to comment Share on other sites More sharing options...
zigzagfish Posted December 16, 2012 Share Posted December 16, 2012 Try and set up a K1 floating bed system have a look in youtube under K1 filter media in your tank it will control amonia and Nitrate if you like to get your hands on some let me know .Lionel Link to comment Share on other sites More sharing options...
firthy13 Posted December 16, 2012 Share Posted December 16, 2012 20% is not enough in my opinion. i do two 50% water changes on all my tanks each week. as jason said, bigger water changes are the go. i recommend looking in to k1 though. apparently its amazing stuff Link to comment Share on other sites More sharing options...
Likoma Posted December 16, 2012 Share Posted December 16, 2012 Hello everyone!I have recently tested the nitrate levels in one of my 6ft tanks and it is suprisingly high. It is stocked with 19 juvenile mbuna and filtered with a fluval 205 as well as a fluval 203 (canister filters).As the fish mature there will be an increase of bio-load on the filters. There are methods of filtration that limit and mitigate the amount of nitrate production.I used to do 33% changes twice a week but since using denitrification filtration methods I have reduced those amounts and frequencies.This said there is nothing as effective, as regular consistent water changes the larger the better."If in doubt,do a water change, water quality comes first and everything else follows."smart personWhat type of mbuna? What is the volume of the aquarium? Are there any changes to the type of feed? Link to comment Share on other sites More sharing options...
TimB Posted December 16, 2012 Author Share Posted December 16, 2012 there are saulosi, fuelleborni, astatilapia latifasciata (not a mbuna i know), maingano and afra cobwe.

TimB Posted December 17, 2012 Author Share Posted December 17, 2012 Tank is 256l approx. Well, I woke up today and found that this tank had sprung a leak and water was drizzling all over the place . I completely cleaned out the tank (moved the fish as well). Had ALOT of gravel to remove. Only then did I find out that the silicon had peeled off one of the joints . Grrrrrrrr!!! Hahaha merry christmas to you as well Likoma! :santa: Link to comment Share on other sites More sharing options...
