Woah, hadn't heard of these. Total ZooMed knockoff with an integrated heater, and pretty cheap at that. +1Lol get an Oase
I have one on my 45 gallon. I was looking at putting the 250 on my 29 gallon. The prefilter cleaning option is very convenient.I run a Oase Biomaster Thermo 350 on a 20 gal ...
I do think it's a little under powered on my 16 gallon. I was contemplating going up to the 200, but the betta likes the lower flow.The Oase Filtosmart Thermo 100 is rated for 20gal, but I personally wouldn't run it on anything bigger than a 10gal.
