45 days I go I set up my 75 gallon tank and started a fishless cycle. I have done a number of them but this one is pissing me off.
After about 2 weeks the ammonia spiked and then with in a week or so the nitrite spiked and sat there for a while and then started dropping. It got down to .5 PPM and sat there for 3 days and then started going up again. And today have a .25 reading of ammonia.
My nitrate are off the charts. Can't even get a reading on the test kit.
I'm doing the Pure ammonia cycle. I started off with 50 LPS of dead rock and added about 5 from my 55 as well as bought another 30 pounds.
I dossed to get the ammonia up to 5 PPM and keep it there with added more when it was needed. When my nitrite spiked I cut down to dosing ammonia to 3 PPM and then for about 3 weeks no sign of ammonia after a 24 hour dosing.
Today my ammonia is at .25, nitrite is at 3-5 and my nitrates are 160+. Ph is 8.4 so I know it's not a PH crash. Had that happen on a freshwater one time.
So what am I doing wrong. When do I need to try?
Anyone saying a pure ammonia cycle should not be done Google it works and I've done it before.
