GardenBanter.co.uk - acrylic Tanks?

No, not really. I have 6 otos in there that work on the glass and
everything else, but over a several week period I'll start to get a very
thin and hardly noticable film of green on the inside glass. I can let
this go for a good month or more before I start noticing it, and then
I'll do a quick scrape on the weekly water change day. Otherwise my
algae problem has gotten to be quite minimal - a small (and getting
smaller) amt of green thread algae and the very gradual buildup of the
glass. The razor scraper does a much quicker and better job than
scrubbers and other scrapers that I've tried. The glass is crystal
clear when I'm done.

Just a few months ago I was clearing out quite a lot of green thread,
but since I've started dosing KNO3 on a regular basis (the eheim
liquidoser is just great!), the other plants are growing much faster
than they had been. My red melon sword had sat for 2 yrs at about 1.5"
high and about 2" across - no bigger. Now it's a good 8" high and 6"
across - putting out these long reddish leaves at a couple a week. My
crypts are doing much better as well. Got some tiny (also for 2 yrs)
amazon swords that are *finally* putting out new leaves and getting
higher. I need more light for them, so they'll continue to be slower,
but at least they're doing something.

I plan to get a glass tank rather than acrylic - I like being able to
use a razor scraper on the inside.
