So.. this is my first time with a built in sump filtration system. In the past I’ve always used hang on the back filters and I replaced and cleaned the media as needed and popped it back into place. Now I’m using a sump with filter sock on my 90 gallon that I’m currently cycling to house my discus. Now I’m aware that what I’m doing is trying to build a beneficial bacteria colony in the sump, but this is the second time the sock has become somewhat clogged to where overflow is running into the sump without passing through the sock. I made the decision to remove all of the plants and rocks I had originally in the setup and went with an open water layout to making cleaning easier. When I discussed this with the local fish store they simply said to throw it in the washing machine with a little bleach. I have other sponges in the sump to establish my beneficial bacteria and I’m wondering how all of you clean your filter socks? I’m debating going to the store and purchasing a replacement sock that I can switch out when this happens. The water level where I’m pointing is rising when this happens, and going into overflow. This is my indicator that I may need to rotate it out with a new one... but how should I clean it?
