Lightbulb One filter two kinds of algae....

During today's disaster of a water change I noticed that the two outputs on my Marineland biowheel 350 each have algae. What is baffling me is that one output has green and the other brown. Could I put some of the inhabitant snails in there to work on that? Is there something else I could do?

PH 7.0 GH 120 KH 0 NO2 0 NO3 <20 AMMO 0 Temp 78, 2 molly, 5 platy, 2 guppy, 3 emerald platy, unknown MT snails and another small variety I can't identify. Anacharis plants, gravel substrate. 55 gallons, 1 6700 daylight T5 1 colormax 48" bulbs.... Regular water changes.

How do I fix this?

I'm not seeing what the problem/issue is. You will always have algae in and around filter outflows. You could scrape it off every week or two if you really want to, but it is natural around spots of high water movement. Some types of algae are even related to water movement. I have always had brush algae grow in the spray bar of canister filters, and that thick dark green algae (not cyanobacteria, this is true algae).

Normally it does not spread into the tank. If things are kept balanced (light/nutrients for the plants) the tank will have no more than the normal algae.

I wasn't sure if it was a bad thing. I keep seeing postings from people getting this kind of tab or that kind of critter to get rid of the algae. That's not including the panic posts about brown algae. I wasn't sure if either of those were bad for the tank or the filter.

Not to worry, this is normal. All algae is normal when you come down to it, but we like to keep it in check particularly in planted tanks where it can slowly kill the plants if it smothers the leaves.
