in case it is true in your case, I might mention the use of Osmocote + pellets. I find they shoot my phosphate way high as O+ is not actually designed for tank use. Some find it works well, some don't but it might is something to be aware of when looking at the options.
No "o" tabs just plain seachem tabs.
I do a religious 50% water change every Sunday. It's the same amount of water ever Sunday. (Marked the tank). I'm very new to all this but I can't see that much PO4 in the water after a 50% water change. But I may be wrong.
I know a lot of people say this; but I don't over feed. They get fed once a day and I watch them finish everything. I also don't feed on Wednesday's. I have a menu per say;
Th, F, Sat - flakes
M- brine shrimp or blood worms
Su - blanched veggies
Tu - peas
W - no feed
Besides the veggies that I leave in for about 15 hrs, nothing hits the bottom.
8 - red tetras (exact name escapes me at the moment)
8- gold barbs
3 - SAE
1 - for the life of can't remember the name. Bigger fish I want to say bohemian Rhapsody but that's not it. (Sorry having a bottle of wine at dinner will do that)
3 - Aminos
3 - Otto cats but truthfully haven't seen them in a while.
Maybe the fauna are adding all the PO4 I already need?
I'm almost positive I need to cut the NO3 but I wanted to test a full EI NO3 dose. FWIW I tested NO3 today, it's between 40-80 PPM, way too high. But if the NO3 is lets say 80 and the PO4 is 10, it's still not balancing out.
