Quick BGA question

[Edvet]

I managed to get a handle on BBA (still needs to improve a bit more, but going in the right direction) now BGA pops up. I've cleaned the filters and the tank more and more, I think i am dosing plenty of ferts (PO4) included.
What could i be missing. (flow should be good)
I am doing a blackout atm and changing 600-800 lit per day

Edvert,
Assuming you have cleaned your filters regularly, BGA is a direct result of poor NO3. This in turn can be the result of either under-dosing, or of suspect flow, or suspect distribution.

5 teaspoons of KNO3, 2 teaspoons MgSO4 and 2 teaspoons KH2PO4 3 times a week. Even did it with table spoons once to see if it made a difference. All the plants are moving "in the breeze" Maybe have to be more proficient at cleaning.

More teaspoons of KNO3 mate. Double the amount and see what happens.

Cheers,

Tomorow the blackout will be finished, I will start with 5-2-2- in tablespoons.

Hi ed
I found that when I suffered this many years back, I sprinkled the no3 directly onto the bga and within a few days had died off and got munched by the ramshorns

I don't think i will be able to do that, i would have to empty the whole tank , i can make a strong solution and use a syringe to squirt it on underwater, not sure that would help long enough.

Did the squirting NO3 solution work for you?

 

[Edvet]

I did a 3 day blackout, combined with large waterchanges, after that it was gone. From then on i start the week with a double dosis NO3 (in my case 10 teaspoons in stead of 5).
