I have a constant BBA problem in my tank. While this sounds bad, it is confined to the substrate and only appears on the Eco Complete. The substrate is a mix of Eco and Tahitian Moon Sand. I suppose it could also be on the TMS but it is just too tiny to see the TMS grains 
The BBA appeared shortly after I began using a Milwaukee SMS-122 pH controller. The CO2 levels are in the 40-60ppm range according to the controller. The controller seems to turn the CO2 on when the pH hits about 6.6 and it shuts off the CO2 at 6.4. The KH is measured with a Lamotte kit and the controller is double checked with a Hanna 98129 so I'm hoping the results are close to accurate.
Could it be that the fluctuating CO2 levels are causing the BBA to grow even though the CO2 levels are in the 40's at their lowest? Or could it be the Eco itself? It has me stumped and I'm getting tired of picking out the affected pieces of Eco with tweezers
Any help would be greatly appreciated!
