nanonan Posted January 2, 2009 Share Posted January 2, 2009 Hi, i'm on my 10th day of cycling my biocube 8 and before i did the water change, the test results are showing like this : 0.15 Ammonia 0.05 Nitrite 10 Nitrate waited a day after the water change and the test are: 0.25 Ammonia 0.05 20 Nitrate..... I tought that the water change (30%) should bring at least my nitrate down......but it went up instead... Is it normal that all my parameters rised because my tank s still cycling? During the month of cycling process, does the number fluctuates like this? I tough that a cycling is when.. Ammonia spike, then goes down Nitrite Spike then go down Nitrate Spike and ...water change.... Does this cycle repeats every other day? How Am i supposed to reach 0 for Ammonia and Nitrite? I added 2 small pieces of LR on main display. ChemiPure and Purigen in Chamber 2. Thanks Link to comment

BKtomodachi Posted January 2, 2009 Share Posted January 2, 2009 For the sake of simplicity, I would just wait in your case. The species of bacteria the process ammonia into nitrite are not the same as those that convert nitrite into nitrate, so they operate separately, and metabolize at different rates. These curves will coexist during the time of the cycle. As long as water changes are small, you will continue to cycle. It may take a bit longer this way. It occurs as a constant process (even after you're done "cycling"), so no, it doesn't occur every day. But yeah, everything seems normal. Link to comment

So there will always be ammonia, nitrite and nitrate even when the tank is fully cycled...because i read ppls test are like 0 for ammonia, nitrite, nitrate...how is that possible?

smedge Posted January 2, 2009 Share Posted January 2, 2009 Ammo and nitrite will be 0 at the end of your cycle. Nitrate will be present at the end of the cycle and possibly for the entire life of your tank. It is traditionally managed via water changes. Also I would remove the chemical filtration while you are cycling. It's only slowing down the establishment of your biological filter. Link to comment

Could i just remove purigen and Chemi pure and put it in a bag then rince & re-use it later? Link to comment

Thanks Well, there will always be things breaking down and dying in your tank, right? This is still converted to ammonia, nitrite, then nitrate. But once your tank is "cycled", the bacterial load you've established is metabolizing this just as fast as it happens. So the end result is that you'll see 0 ammonia, and 0 nitrite. Nitrate is generally removed through water changes. Could i just remove purigen and Chemi pure and put it in a bag then rince & re-use it later? Yes, that would be fine. Link to comment
octoberfest Posted January 2, 2009 Share Posted January 2, 2009 Wait until cycle is complete before you do any water changes. Link to comment
