I was given a canister filter for my 150 gallon aquarium that I'm using to temporarily keep my koi until I sell my house and move into another. I have lost one of the plastic nuts that connects one of the hoses to the canister. Unfortunately the canister doesn't have the manufacturer name, it looks like it was purchased in bulk and relabeled. I've looked at the local pet shops and found canister filters that are similar but no one sells replacement parts.
I've also searched on-line and can't find anything similar. The filter resembles some of the Fluval filters.
Does anyone know where I might find one of these plastic nuts?
