aLkAh0LiK Posted August 25, 2011 Report Share Posted August 25, 2011 How do I reduce the NO3- in my tank? don't have much, but I've got Seachem Prime, will this do the trick? Should I just give it a double dose? Link to comment Share on other sites More sharing options...
discus_noob Posted August 25, 2011 Report Share Posted August 25, 2011 Do a water change (say 30 percent) and check levels. If still high, then do another one the next day or within a 12 hour period just small ones that will not cause too much of an inbalance to your filtration and recheck levels. Double dosing prime on w/c wont hurt in any way Link to comment Share on other sites More sharing options...
Mackayman Posted August 25, 2011 Report Share Posted August 25, 2011 NO3 ?... Do you mean nitrates ? If so, to the best of my knowledge, I don't think any amount of Prime will reduce that. As above, more regular water changes are prolly the best bet. Brendan Link to comment Share on other sites More sharing options...

__CAV__ Posted August 26, 2011 Report Share Posted August 26, 2011 (edited) Only real way to remove nitrates is water changes 25% waterchanges once a week will lower them. Have a read of this it may help http://www.qldaf.com/forums/articles-faq-20/nitrogen-cycle-103/ Cav Edit. Also you can test the second you finish ur water change, Test before and after your water changes and you'll be able to see how much nitrates your taking out with ur water changes.

neyund2 Posted August 26, 2011 Report Share Posted August 26, 2011 have a tank above the main tank, put in clay balls, and green leafy vegies (eg basil, lettuce etc) and have a fill and drain system pumping water into that tank every 30 mins. That sould get rid of your nitrates. cheers dan Link to comment Share on other sites More sharing options...
aLkAh0LiK Posted August 27, 2011 Author Report Share Posted August 27, 2011 the NO3- looks like its about 20-40ish.. based on the colour chart Link to comment Share on other sites More sharing options...
Asshh Posted August 27, 2011 Report Share Posted August 27, 2011 I'm going to give Neyund2's method a go, except put it below the tank and let it fill up slowly. Then pump out the water with a small volume pump on a timer. Aquaponics!! then i call start selling lettuce instead of fish Link to comment Share on other sites More sharing options...
neyund2 Posted August 29, 2011 Report Share Posted August 29, 2011 hey ash, r u the one building a fish room atm? if so I suggest you seal the roof space so you don't loose a lot of heat during winter and also paint the walls with the anti mould stuff in it. If you have windows in the fish room, sit your planted vegie tank there to get the the sunlight. cheers dan Link to comment Share on other sites More sharing options...
regani Posted August 30, 2011 Report Share Posted August 30, 2011 How do I reduce the NO3- in my tank? plants, lots of fast growing plants or floating plants like frogbit or duckweed, they will get your nitrates down. doesn't work too well if your fish eat the plants, though Link to comment Share on other sites More sharing options...
