just a quick question on wet dry filters. ive read that for a hob filter you need about 10 your tank capacity and for canisters about 4 times capacity but i havent found what type of capacity is needed for a trickle system. also how do i figure flow rate if im using a 3/4" pipe from my tank to my sump? i read all the links that have been posted on the site and these 2 question have still eluded me. thanks in advance for any input

it all depends on the setup of yr trickle system please post a pic and i should be able to advise u.

I have no idea of these filters systems but you cannot have to much filtration so if it doubt go for the larger one

i plannning on using a 150l tank in basically the same design as the on the link.

im also thinking about 3/4" tubing for my intake and return lines.
