Algae Scraper...alternative

I have a 30 gallon tank full of cheato. Lit by two 24" t5ho bulbs from top and one from side through the glass.

My floats from the amount of bubbles it creates. My nitrates have been low since day 1.

I'm planning the same thing for my new 300 gallon setup. 100 gallon sump with a large area for chaeto. I'll post a pic tonight or tomorrow of the current setup.
