What is the photo period for benificial algae

[scapone]

I have a ac300 and instead of media I put calepra algae in there. I got one of those clip on lights from home depot for 10 dollars. It uses a 25watt light bulb. I am wondering how long does this light have to stay on. I did no modifications to my ac300 just added the algae plus some more clean up crew cause I had an bad algae bloom. here are pics:-*

I'd either run it 24x7 or on a reverse photoperiod from the lights on your tank. Both will greatly help your tank by not allow a PH swing when the lights go out.

 

I'd also swap the light for a 13W powercompact bookworm ($20) or a 2x13W powercompact assembly ($25) at Lowes as they are more water resistant and can layed directly across the top as well as having a better Kelvin rating (6500k) as the bulb you have will cause more nuisance algae then macroalgae growth.

So basically i need a whole new fixture there isin't a pc light that fits that?

There is a 10W Coralife PC that screws into it that costs $10 online and $15 at local fish stores. IMO you're better off dropping $20 or $25 on the fixtures mentioned above and using the current one as a desk light.

I don't know! I've been reading over at RC, alot of people light their fuges with 2500K (incandescent/halogen/gro-lux) bulbs and see much better macro growth.
