i have an aqua-tech 5-15 and it's doing a decent job on filtering my 10 gallon, but i wanna upgrade and so i want mod the filter so it can filter a 20 gallon tank just as well. any ideas?? it already has 100gph btw
My first filter was that one. I thought it was decent until I bought an aqua clear. It's so much easier to clean. The motor twists off so you can clean the impeller. The flow is adjustable. The filter media fits into a basket kind of thing which is easy to pull out without moving the filter. I also use polyester fiberfil from Walmart instead of the sponge and no charcoal.
I like it so much I bought a larger one for my 33g.
get another 5-15? two of those would do a fine job on a 20g. is the impeller removable? sometimes filter companies use the same size impeller but with a different amount of paddles... or whatever their called, to change flow. sometimes you can change out the impeller to get different flow but aqua-tech most likely doesnt have a good source for replacement parts.
