i just ordered a couple of these.
cgi.ebay.com/Sponge-Filter-Discus-Guppy-...sidZp1742.m153.l1262
I am going to use them on my 11ltr tanks i wanted to test them so i can plan a fish room for the new house (when ever its built)
I am hoping to have my stacks four high the top tank as a water store or in an emenergy hospital tank. i was think of heating the room and adding heaters were a higher temp is required.
i will be using the above filter and on smaller tanks and possibly diy sponge filters on the bigger tanks
I am hoping to create am air system using 1inch plastic pipe and connectors stop ends this will be sealed and drilled to place connectors for standard air line to run filters.
but what type of compressor should be used! where to get them! and were to locate it. considering it will start off in the house!
