Well, I ran out of Nitrite/Nitrate tests and have no money to buy a new one. I do still have ammonia test kits, but I'm noticing that my 30g tank holding my Ps and my oscar is getting cloudy. 3 weeks ago ammonia was intense, 6-7ppm and the water was really cloudy. I did a 50% change at that point and the ammonia didn't seem to dissapate immediatly. I waited a day and tested it, down to 4 ppm, then 2 days later it was at 0. I don't have a nitr*te test kit anymore, no money and the LFS is out but my water is getting really cloudy again. I do a 50% change and it's clear for a day and then cloudy within 24 hours. I'm wondering if it's cycling out my nitrites or if there's something else going on in there. I've also been noticing a very stubborn deposit on the inside of my glass. It won't come off no matter how hard I scrub it and it didn't start appearing until the cloudy water started. Any input???
