300w of lights for 12 hours
nitrates 20ppm( 2tsp/day)potasium nitrate
amonia 0
potassium tsp/ day
nitrite 0
macros (every second day)
CO2 4 bbls/sec(press. bottle)
iron once a week 5 ml

I'm not sure if you have this in Canada, but if you have a wal-mart,or any type of store to that nature, they have this stuff that's called Algae Destroyer Advanced and it doesn't harm plants at all.

Immediate onservations are the nitrate level is a bit high, I'd halve it. Do you test your Fe (Iron) levels? and for chelated iron? You may find it better to dose iron in smaller amounts more frequently say 1ml every other day to start. Do you dose micro nutrients too? Not sure why you need to add extra potassium if using KNO3 so I'd stop that for now. Finally add some fast growing stem plants back!

If you were algae free before, probably just need to get your balance back. Look at what plants you removed and adjust your dosing accordingly. IME, algaecides lower O2 levels, if injecting CO2 might set up dangerously low O2 levels for your fish. I have suffocated fish, not really a worse feeling than murdering a beautiful fish.....DC

For a quick fix, i have found "Algae Destroyer" to be effective.
But you really need to get to the root of the problem to be effective in the long run. I too think that your ferts might be the cause and you should cut down of fertilizing until you get the algae under control. Another temporary quick fix would be to go get some of those phosphate / nitrate absorbing resins, but remember to take it out after a day or 2, lest it leaches everything back.

Like paul said... go get some fast growing stem plants.

Everything started couple of months back with cyano bacteria bloom.uped my nitrates to keep cyano at bay after five days of erytromicin.At same time trimmed my fast growing plants too much and then came green hair taking over java moss and most of slow growing plants.Bumer.
