Ok, aquaclear sponges aren't the best. Im using BRS ROX 0.8 which is much smaller than the normal carbon I have seen.... I works its way THROUGH the sponge.
What do you think of using a smaller cell sponge, like cheap kitchen sponges? As long as its new and doesnt have any soap or anti mold stuff it should be good right?
Any other ideas? maybe wrap screen around the aquaclear sponge and use it like a french coffee press?
