i need to know if it would be okay to make a sump out of ply wood with a pond liner or something to line it??? also is it okay to use pvc pipe as a j tube for a hob over flow? i want to boost my gph a little so rather than the 1 inch tube it came with i was thinking 1.25 or 1.5 and for the sump i was thinking a modified Berlin stile set up. with twin filter socks then some bio stuff then a pump.
