This tank has been cycled about 3 months now and while I understand that algae is common in new tanks, I couldn't understand why I was getting so much so often. I was doing 50% W/C every week religiously using a 75/25 RO/Tap mix and I also had a cleanup crew of 11 Nerites, 2 Ottos, and some Amano Shrimp. They did a great job but no sooner would they clean an area that it would be back the next day. I was pulling my hair out.
Then I read over the PPS instructions again today and read something I had missed before. The dosing schedule is based on, "a heavily planted tank"! What?! So I continued reading about testing for NO3 and PO4. The instructions mentioned NO3 around 20PPM while mine yesterday was 80 PPM! I have just 8 clippings in my tank I bought from a fellow forum member. They total probably 30" linear. I'm so pissed at myself for not seeing this.
So my question is how do I determine what I actually need for my tank? Maybe cut it to 1/4 of the normal dose and then test until I'm around 20 ppm of NO3? Strangely, the PO4 is at zero. I did put some Purigen in the tank recently to remove come brown color from the driftwood. I'm wondering if it could also be removing other things.
Anyway, I thought I would mention this in case someone else runs into the same thing. It was driving me crazy and it was such a dumb mistake.
I tested again tonight and NO3 was just 10. I don't get it. The other problem I'm having is that according to API, my PO4 is at zero and has been every time I've tested it. Wth is going on?
