Lighting thought

Opinion on this. http://www.ebay.com/itm/T5-Quad-48-T...item43bd0d5d2c


Or should I go with Hagen 2x54 ballast system, buy the 2 48" reflectors, and 1 marine white and 1 blue bulb. Prices will come out to be close in price.

What are your thoughts? I have a 90 gal bowfront Mbuna tank. All rockscape, my goal is to grow algae on rocks.

Algae is easier to get when you don't try hard to get it. A few of my tanks have nothing but a garbage t8 single bulb running and have an awesome sheet of green over all the rocks. Just lighting won't easily grow algae, you need an overstocked tank/nitrates too. Its the light/nitrate combo that grows the stuff as the algae has something to feed off of.
My 75g troph tank has a http://www.ebay.com/itm/LED-Pent-48-...item19df8e1816 over it. My holey rock is probably just a few months away from being coated in green algae with it on 14ish hours a day

I had those crappy single t8 bulbs over another tank and all it produced was that brown algae. Definitely trying to avoid that.

Algae is algae, if its growing brown algae, your parameters are off. And really, new tanks will start off with brown algae and eventually turn to green over time when it establishes itself. You will not just grow green algae right off the bat

how come you want algae?

I like the looks of it on the rocks and Mbuna are grazers, they will eat it off the rocks.

i got a bunch of brown and green algae on my rocks. Is this bad for my fish or tank? How should I get rid of it if it is? Thanks
