I was going to ask this in the equipment section but then I thought this might be a good place. I have a riparium that's 24 inches high, currently I have a couple of small internal filters in it (about 20 gallons of water) but was thinking about getting a canister filter for it instead. I have no experience with canisters and was looking on Youtube... it appears that the output may not be long enough to fit a riparium (my water level is about 9 inches below the top of the aquarium)... is that correct? Is there a solution for that?
There are definitely solutions. To start, what brand and model filter do you have/will you be getting? Some filters shold have stock input/ouputs that are long enough. If not, options for what can be done kind of depend on what canister we are talking about.
If it is a Fluval, Hydrophyte (a member here, and owner of Riparium Supply) has done some modification to his. I am sure he will chime in pretty soon here.
I'm not real sure which kind I will get if I get one. I would like whatever I get to have black tubing so it will blend in with the background. I don't care for the green or white tubing I see in some peoples aquariums. Do you know anything about the Rena's? Or have a suggesting on a brand?
Making DIY PVC inflow and outflow pipes is the best way to go, IMO. Drop by your local home improvement store and be creative. Get some PVC, connectors, appropriately-sized hose fittings, PVC cement, and hose clamps. You can use a drill to create the holes in the inflow pipe.
