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?

I've never used the PPS PRO style of dosing so I can't help you there. I can however tell you that there's a very good chance that the Eco-Complete you have is soaking up the ferts you are dosing.

Just a noob

It's a pretty flaky dosing system, for sure. I've used a PPS Pro dosing mix for the last couple of years, and throttle it based off nitrate levels. On my extremely heavily planted 90 that works out to 3ml/solution every other day. I feed a fair amount of frozen food without draining it first too, which is going to be adding nitrates for sure. I still have BBA, so not a perfect system by any means (on my part).

I use pure RO for changes, which are no more than 10 gal a week on a 110 gal system (90 + 20 sump). Stocking is 9 brochis, couple dozen pygmy cories, 40+ otos, couple hundred shrimp and a farlowella.

Define "flaky" for me. Is PPS not a well adopted dosing regime? I mean, EI is of course the one I hear about the most but I thought a lot of people use PPS. Thanks for the thoughts on Eco-Complete though. I have read that it begins empty in a sense and absorbs everything around it but I would assume that at least some would stay in the water column. If I had to do it over again, I would have spared the expense for the ADA soil or equivalent.

EI is just a much easier system. You are essentially flooding the water column with a somewhat excess amount of ferts where the PPS system you trying almost to get the exact amount of ferts needed for your aquarium.

Just a noob

Not sure about that. The PPS-Pro doesn't try to get close at all. Same thing. Dose large amounts and do a 50% w/c each week. Maybe you are referring to the regular PPS Classic.

By flaky I mean I have no idea how people don't bomb their tanks using 1mL solution/10 gal/day. My nitrates would be off the charts if I did that, and I have extremely heavy submerged AND riparium growth. Lots of water changes I guess, but still..

I should be fair though, it works for a lot of people.
