How long has our tank been established? Brown algae (diatom) is usually a sign of an immature tank maturing or of a lightening/cleaning problem.
I'd first try cleaning your tank twice as frequently, or doubling the water replacement each time, adding live floating plants like water sprite, and only after those don't work I'd think about fish/snails.
Otos may not like your water if it's too hard, but they specialize in diatom algae. Mollies do eat a decent amount of algae, but I've not seen them eat off glass...although they will pick at any patches big enough to rip off and eat.

Yup this is what I was told.Before you go out and buy algae eating fish and adding to your bioload and possibly the problem in its self. Try to figure out what could be causing it like lights or water parameters and see if u yourself can get it to stop or at least keep it manageable.Lots of us have to wipe algae off are plants and sides from time to time.Another thing is after u get something to eat the algae it might not grow back fast enough for them to feed.So now u will be adding more food to the tank to support them.How long has our tank been established?
