sin01bst thanks for the response. Ok cool eheim on the extreme left chamber, one pipe running to the top of the tank... will the eheim be submerged under water? or do i have it outside of sump with 2 tubes attached (intake/outake)? or inside sump with just one tube going as (return) ?
Will leave the UV for now if its not vital, as this lot is using so many sockets already!! The tank is 6ft... So on your setup you had an air pump running in the sump... Did you have any other filters running? External cannister etc? Will that (fluval)be running completely seperatley to my sump? I figured it would have to be involved in that someway?
