DIY filter - 5 gallon bucket
Im also trying the 5 gallon bucket method. This idea came to me after the guy at the pet-store tried to sell me a canister with a external pump for about $300 ... I though why not make by own canister ?
My design is compartmentalized with a few acrylic sheets cut up, your bottom up design seems easier to build but harder to clean since the first stage is way at the bottom.
My issue is that nothing adheres to the plastic 5 gallon Home Depot buckets. Not epoxy. Havent tried PVC cement yet, Im out... I made a silcon O-ring on the top of the bucket to insure a good seal, but the silicon peals off very easily. I cut a groove in the top with my dremel tool, and that helps the silicon adhere a little better, but not like it would to glass.
Anyone know what kind of glue sticks to those buckets? I'd like to stick cleats in the bucket so my compartments can slide in and out on the cleats.
