Newbie need some advice re: brown algae eaters

hello - I have a 20 gallon long tank that's been up and running for about 2
months. It currently has these fish:
4 zebra danios
4 cherry barbs
4 marigold plattys
2 bronze corys
1 oto
I've been having a bad problem with brown algae. I know that oto's
eat brown algae but oto's seem not to survive in my tank (it is non-planted
and has 0 ammonia, 0 nitrites, 15 nitrates, water on the soft side (6 dh of GH
and 3 dh KH) and fairly alkaline pH (about 7.6). So far I have only managed to
keep otos for about 3 weeks. I was wondering if a bristlenose or some other
type of pleco might help. Would a bristlenose be too big?
Thanks in advance.

That brown algae is just a part of the tanks stabilizing process. As soon as the silicates in the water column are exhausted it will go away by itself. It's usually only annoying for a month or so. Otos can be a bit sensitive to shipping, so you might try three or four more, and acclimate them slowly before you add them to the tank. Hope that helps.

Thanks for the info - will the silicates 'disappear' over time or will they be replenished
each time I do a water change?!

Otocinclus does best in a tank containing live plants. Ever thought about getting some? it'll make keeping the tank in prime shape a LOT easier, and with your fish, it shouldn't be a problem, keeping some Cryptocorynes or Javafern alive.
A single bristlenose can be kept in that tank; just get a young one (1-2"); he'll clean out algae fast, he doesn't need wood (unlike clownpleco's and the like) and he won't get too big (4" or so)
Common Pleco's get up to 45-55 cm, wich is -of course- WAAAYYY out of line.

thanks - I've been thinking about plants -- is 20 watts (24" bulb) on
a 20 gal long (12" high, 12" wide, 30" long) enough for low light plants?

Plants are well worth your while. Java fern, java moss, hornwort, crypts, maybe anubias nana should do ok. Or throw some more light on there; even the "low light" plants will appreciate it.
