Hey, I have a tank in the process of being made. It's 5 gallon and in the shape of a water cooler. I am looking for advice with some of the parts. First I was looking for a possible external canister filter so that I can run the hoses under the bottle and in the stand out of view. So far I have been having trouble finding a filter of this type and size. If anyone knows of where to find them or has any suggestions it would be nice to get some input. I am also going to need to customize some lights on this thing. I could use some info on dos and don'ts for this. I plan on putting the lights on the bottom. Any suggestions?
