First off, I admittedly know nothing about plecos. My only experience is I have about 30 or so bn plecos scattered through my tanks as diatom controllers, and they are brown algae devouring machines. All are very healthy and not shy in the least. I have never lost a single one.
I decided I...
I'm looking for a UV for my 120 and one for my 75. Can anyone recommend a brand that hangs on the outside of the tank and has a powerhead included?
I intend to run them 24/7.
Also, I don't want to spend a lot of money 'cos I'm poor.
Thanks,
Francine
