Algae??

any idea why this is starting to grow?

My 65g tank has been running smooth for 7+ months and this is just starting to show

I bet your nitrate is very low and phosphate is higher. 100% dino grower in my tank.

I just tested phosphates and they are not high at all. I add this bacteria stuff every other week to keep nitrates/nitrites down.. but don’t think that’s the cause. Nitrates and nitrates are pretty steady. Could it be something in tap water I’m topping off ? Or lighting ?

Low to undetectable phosphate triggers dinos for me. Feed heavier and they go away (for me)
