BRS Universal Carbon Block

[spsick]

I don't think it's that big of a problem. I've already converted several stages to granular carbon. I think the resistance of the membrane and flow restrictor would counteract it.

Channeling is actually more of a problem at low flow rates. I was advised against using a large floor standing carbon tank for this reason.

But to your point, it’s so much cheaper you could afford to replace more frequently and still be ahead.
