I am battling algaes for a while now, read though various forums and tried everything apart from chemicals. I know that to be successful with algae I need to get all in right balance, but I must be missing something, just don't know what. Please help if you can.
My tanks is fluval Osaka 85 gallon, rather deep 30 inch or so. Have been established for over a year.
Substrate Eco complete. Lights: 2 x kessil amazon sun.
I am dosing EI:
3/16tsp K2SO4 tree times a week
and plantex CMS+B 3/16tsp tree times a week.
Adding pressurized CO2 through inline diffuser around10-15 bps.
And doing weekly 50% water change.
My parameters are:
KH: 20 ppm
PO4: much more then 5
I know that phosphors build up is really high because even after water change it still test for maximum (5) that test I have measures. ( tap water I use for wc does have a little phosphors but test shows usually around 1)
I assume my plants doesn't absorb enough nutrients and that causes the build up.
Also I am getting fuzz algae all over the tank which I read somewhere that it's a sign that plants leak nutrients back to water.
On various forums people usually point to CO2 being the main cause of algae. So I kept unceasing CO2 slowly to the point that one day I overdone it and it killed all my fish when I was at work. I don't have any fish since then - just 2 Amano shrimps which I manage to resurrected after that accident.
So I think my CO2 is pretty high.
Now, I am out of ideas as what to do. I must be missing something. Just don't know what it is.
Please help if you can.
I forgot to mention that I am also dosing 15 ml excel daily.
And my lights are on 8 hours/ day
