You're assuming 1.022 is an accurate measurement. How many times have you seen someone report a low SG like that only to find it was measured with either a hydrometer or a poorly calibrated refractometer? If it was measured with a hydrometer it could be closer to 1.019 or it could be considerably elevated. Hence the reason it's important, firstly, to find out how these parameters were tested.

But I still think the flow is way too low and I would be surprised if phosphate and nitrate weren't elevated (despite the 0 values reported from testing) given the report of hair algae growing. I'd still like to see a picture of the tank.
