I am setting up a 30 gallon tank and waiting on the shrimp to decay and start my cycle. Was digging around in storage and pulled out my little 10 gallon tank to see if my little 10w heater and filter still worked... and they do. I was actually thinking about putting the small filter that came with my 10 gallon tank in my 30 gallon tank along side my Penguin 350. It's just a little thing but I'm thinking it will provide my water flow... wouldn't it? Anyway I just thought I'd ask your opinions. Would it be useful at all to put this little thing in there or is it not worth it? :neutral:
