original [ok, so im gonna use rock as a substrate. and so my tank would get dirty fast. ive seen under gravel filters made with pvc to keep debris from getting trapped and keeping the tank crystal clear. my question is ho can i do this? i have a rena xp3 that i would hook it up to. its a 65 gallon tank and ill tell u any other info you will need. dimensions are 36L x 18W x 24H]
ok, so i have decided on how i am going to do this but im not sure on a few things. i plan on covering the bottom with eggcrate and than putting pvc ontop with holes drilled in it everywhere. but one question is how much pvc should i use and what pattern should i use on the bottom. and i was thinking of 1/2inch pvc. how does this sound to ppl? or should the pvc be under the eggcrate?
