I allways dend to have very high levels of PO4 in the tank, and I allso have quite an high ammoumt of livestock, but also quite a lots of plants too.
Yes I know PO4 comes from the food we give to the live stock. But does it come from elsewere?
I keep large roots, mangrove type, and offcourse they tend to rotten, but does they give away any PO4?
And in the bottom layer, is there an depot of PO4 there? I have only sand and gravel. But the tanks are very old and filters are big.
How much PO4 is there in 100 grams of pellets or flakes. I use tetra pro´s flakes in an eheim feeder to feed onece a day, and refill every two weeks. max 1 dl/2weeks
I do 50% waterchanges every two week all year around, pretty good growth, due to Fe and KNO3 ferts, but never PO4. And the levels of PO4 is almost always way over 1,8ppm. When I get a lots of algeas like BBA there is high levels of PO4, and when I try to give small amounts of PO4 in ferts i get more BBA
Where do my PO4 come from?
Thanks for taking time to read.
