this question use be a separate forum itself but i thought i should ask here
i have a sponge filter attached to my HOB power filter intake tube so it prefilters before the water reaches the main filter cartridge
i recently set up a DIY CO2 injection with an airstone and it was set up so the bubbles were sucked up by the sponge
i have noticed the sponge was building up this slimy thick clear layer the constricted the flow of water and now i have to squeeze the sponge more often to open up the flow
what is this build up and can i get rid of this? i decided to move the location of the airstone far away from the sponge/intake because of this
