How can I still have BBA

Even though there is less of it now I have been fighting BBA for some time and cannot figure out why it is still present and slowing growing. I have a 125 gallon medium planted set up with a Fluval FX6 as well as a Hydor Pro 600 for filtration. I also have 2 circulation pumps so along with these 2 filters I have really good water flow around the whole tank. I also recently purchased and installed a solid CO2 reactor on the return hose of the Hydor Pro 600 canister filter so the CO2 is being dissolved nearly 100% in the water with no bubbles. The colors on my Cal-aqua 2 bowl CO2 drop checker are just about the same. For lighting I have 2 - 36" Finnex Ray 2 LED fixtures on the rear portion of the tank and in the front I have a 48" Finnex Planted Plus LED fixture. All three light fixtures are suspended 30" above the substrate. I also try to be good about weekly water changes of 40% to 50%. The only thing I have not been doing is fert dosing for now.
The gravel has some BBA along with various plants and I see new BBA growing in small tufts on the glass. What am I missing or what am I doing wrong? Any suggestions would be greatly appreciated. Thanks to all responding members.

Controlling Algae

Hello Aqua...

Algae is controlled by fast growing stem plants that use up excess nutrients in the tank water. Anacharis is one of the best. Get some individual stems of this plant at the local pet store and drop them into the tank. It grows best floating close to the light source and doesn't require planting in the substrate. The larger it gets, the more nutrients it uses. It also gives off a mild toxin that most forms of algae don't tolerate.

This is the first plant that goes into my planted tanks.

I generally harass the stuff whenever it appears in my tank's.
Pull it off wood,rock's,pull it out of substrate,clean it from glass,spray bar's,heater's,etc.
Keep filter material clean monthly.
I personally believe it is tied to maybe excess organic matter and have found that the above measures work for me.
Eventually,the stuff get's tired of trying to get a hold in my tank's.
Volumes of thread's abound about possible causes in high energy tank's,low energy tank's,low flow,high flow,etc.
Only can share what work's for me.

Thanks BBradbury and roadmaster,

I will try your suggestions and see if they help. I am planning to move this tank to a different location in my mancave this fall so a thorough cleaning will certainly take place. I am also hoping kind of a fresh start will allow me to get a handle on BBA if it rears its ugly head in the future. Thanks again.

pull out your hardscapes and steam them when you get a chance, always good to sterilize things so that you only have spores in the water column, then you can get rid of them by water changes

Thanks D.... Hadn't thought about that. Wish I could do the same to some affected portions of my Eco complete substrate but I am sure that steaming process would kill off any beneficial bacteria that has built up over time>
