any issue with water not making it to the filter sock? it doesnt seem like you have a strong seal between the filter socks and glass they sit on.. i was wondering how much water is getting under the plastic ring and not into the sock. any issues with the sock possibly lifting off the glass it sits on?
i wanted to do the same thing with 3 corse, dropping down to 3 fine, finally trickleing over a wet dry with 8-10 gallons of bioballs
