Aquarium Advice Addict
I posted this in the planted section because it might be related to CO2 injection.
I am using DIY CO2 and I feed it directly into the filter intake tube. The other day I noticed that the flow in my AC50 HOB was less than usual. Coincidentally there has been a whitish buildup at the end of the silicon airline tubing that feeds the CO2 into the intake tube. I have seen it before but usually just wipe/shake if off. This time it built up to the point of impeding water flow.
Any idea what this could be? I am thinking it is a type of fungus. But one that favors CO2? I let it dry out and it was somewhat fibrous.
