I know that low/unstable CO2 in and of itself does not automatically cause BBA. I have three tanks here that can testify to that, I've had every CO2 issue under the sun and back again and cannot trigger BBA. I can add BBA to a non-CO2 tank and it dies. There has to be a reason for that. Something is lacking in my tanks that prevents BBA from thriving. Whatever that something is, doesn't affect my plants. I dose all macros and micros regularly and my plants are thriving for the most part.
Tom Bar said:I've "cured" BBA is a dozen tanks by simply reducing the light intensity.
No other changes where done, this reduces CO2 demand.

However, the levels of both light and nutrients are still much lower than any plant before they become "limiting" to algae growth.
Gerryd: Here are the answers/comments.
As mentioned, an Eheim Electronic Pro 3 at 450GPH rating. To ensure that water flow was maximized,
I placed the spray bar vertical pumping from left to right across the back wall. My DC has always been placed
directly above where the BBA starts to grow (on the Anubias). I placed the DC in the slowest flow in order to
ensure I had adequate CO2 levels in that area.
Correct, EI-6 Hour lighting-CO2 running 24/7 via an inline reactor.
You really have me thinking when you say that my short photoperiod may be a limiting factor. It would be great
to hear what other people on here think of this idea ...
Oh I'm sure Tom is correct... but I don't see what next steps to take - I've taken them all!!!
I agree that explaining things to peers is extremely helpful. That is why I am here.
So what steps do you think I should take next? Keep in mind I do not have lots of stem plants, the drop checker is
bright yellow and lighting is dual t5.
Could the 50 cardinal/rummynose I have be causing problems? They don't get all that much food and sometimes none at all.
I just know what needs to be focussed on the most at this point. Everything I know is important to do/check is done.
