diffusing light with tannins
 
i have 2x 24w over a ten gallon and the algae is rampant. i also need to lower ph for fish and plants. can i hit two birds with one em maybe three or four cattalpa leaves? they diffuse light and lower ph but dont know what qualities of the light they diffuse.

To clarify: can i use cattalpa leaves to leach tannins to blacken the water and thus diffuse the light; rather than remove a lightbulb?

why would you want to do that?

to reach your objectives, might i suggest adding floater plants to target the nitrates while also diffusing the light intensity to more agreeable levels. The floaters would start to absorbe the excess light and consume the nutrients in the water column to hopefully hasten algae progression.

Thats a ton of light man. You can get away with half of that.

ive only got diy co2, and the light is too much and algae is terrible. but thought if i took away a whole 24w the lighting might not be sufficient to grow my carpet plants.. ill put in a few pieces of frogbit, i just thought that they dont diffuse light more like block it completely. but finally yeah i took out a bulb and will experiment. i tried carpets before and thought it was the lights you see but now maybe it was ferts. I've got root medic root tabs now after the rave reviews so fingers crossed.
