hello All, this stuff is killing my plants.

All water parameters are good, i have stopped dosing dry ferts
i have cut a lot of the algea out
i have not stopped co2
i have lights on full 3wpg
i reciently did a 60% water change.
gh 13
ph 7/6.5
kh 8
amonia 0
nitrate almost 0

what must i do ?

any advise will be great
 
First advice. Keep dosing
What kind of co2 setup are you using? DIY or Pressurized?
How many hours a day are you running your lights
What size tank (80 Gallons?)
Can you turn off, or remove, bulbs from your light fixture?
Do you have a drop checker with 4DKH solution?

BBA comes around when there are fluctuations in the co2 levels in the tank. Keep up a good amount of co2 (~30PPM as indicated by a drop checker) and you should be ok. your bba will go away.
 
i agree with coach. as well you should do something to raise that no3 level before you're plagued with another algae to complicate things further.
 
A black out if needed?
 
Agree with suggestions above, as they are mostly likely to help. I've been fighting BBA for quite a while, and found that my micronutrient mix was causing flare-ups of BBA. My theory is that it was the iron levels that did it, and I've had to cut back and use smaller and more frequent doses.

BBA might be a stubborn resident for a high-light tank, and in my case the only thing that really knocked it back was a school of Siamese Algae Eaters. It was a last-resort, as adding fish has its own set of problems, but it looks like this was my long-term solution.

Thanks this helps , i believe my co2 is at about 30ppm, i have recently been messing around with difusers, so i will stop and let it run.
 
I agree...most likely your CO2 is fluctuating as the mix wears out and if you are only running one bottle then all of a sudden when it's changed you get a spike. Your CO2 concentration is probably too low in general unless you have like 4-5 mixes going.
 
i have 3 bottles running at a time(300g sugar / 10g dry yeast) so they produce a lot of co2, 4bubbles a sec, they usualy last for 10 days in rotation, my drop checker is a light yellow, from my reading this is fine, am i wrong?

I dont always run the 3wpg, most days its 2.25
