Most of my searches have turned up information about algae growing on the sand bed. I've got green algae apparently staining my pool filter sand grain by grain. I'm prepared to replaced the substrate (I've got a fresh bag of the same sand on hand), but obviously don't want to have to deal with the same problem later.
I think my main problem is that I'm confused by what I've read about controlling algae. Increase light, reduce light, shorten lighting period, add vascular plants.. I'm not sure what to do. I tried keeping some anacharis - it lasted longer than I expected with my Africans, but still not long.
I just switched my lighting to two 20W xenon puck lights from a 4 foot two-tube 32W T12 fluoro with blue actinic and 10k bulbs. I'm not sure it's helped, and I think the light is a bit too orange to suit me.
What do I do?! :-?
Thanks.
