hey everyone i was thinking of giving rdwc a try ive seen people on youtube with 3/4 return lines and ive seen some with 2" return lines in 5 gallon buckets which do you think would work best for 5 gallon buckets? wouldnt 1 1/2 do just fine? i was thinking putting a small pump in the res and running 1/2 pvs thur the top of the bucckets..drilling 2 or 3 small holes in the pvc and letting it spray 2 or 3 small streams down towads the bottom of the bucket..to make more bubbles with air stones.on the botttom also...
