Do you do weekly water changes? Just do that.
Set your Controller for 6.6-6.7 @ a KH of 4.

Sounds good. Do 50% water changes weekly then.

Sounds like Diatom mats. You need more CO2 at this high light value.

Check out the www.sfbaaps.com under "references". Your going to need K2SO4,
KH2PO4, and certainly KNO3. Then you need to add traces.
Your tank is starved. It'll do well when first get going but you did not add
anything after that. Then you get algae. Light(you have a huge amount), CO2,
(you likely do not have enough unless your KH is at 7 or 8 which is
unnecessary when your KH is 4) and nutrients. Your missing the last part and
need more CO2 very likely.
