Yes unsightly. A chore to clean. Parts to fail however, I have always had a BH on the job somewhere. They are my workhorses for my smaller tanks. Polisher, BB booster, decon and the list goes on. I have a small team now that reside in a tub where they are fed and running. I read an article some time ago about having a hanger with coarse filter only in med tanks to allow for dosing. Today I really needed to speed up a tank for space. I ran it 2 weeks snail mode, added some feeders all the while with Stability and usually that does the trick. I’m running a large sponge and a mini power head for filtration. 20 gallon tank and it’s being lazy. It’s been 3 weeks so I’m doing daily WC now to keep the NH in check. Go to the “gallows” tub, grab a hanger and pop it in. Guess what happens in a few days? Why don’t I do this from the start? Not there when I need them. When I need them, it’s for a situation that needs attention now. Any way as soon as things are rolling, out she goes back to the tub. Just thought I’d share something working for me.
