Alright here are my final plans, any suggestions or is anything wrong here?
I plan on using 1" PVC
for the overflow. I have to use 1/2" flexible tubing for the return because the outlet of the Mag 7 is 1/2". Plus I also have to take a couple of turns so I don't want any hard 90 degree turns to limit my flow. Any ideas for what type of flexible tubing would be best?
I have the display tank at a glass shop getting drilled tomorrow. The guy said he might not have the bit to drill the 1/2" return hole, would I be able to use some kind of adapter and have him drill a 3/4" hole?
Also, it's not in the picture but I'll be putting a ball valve on the return after the pump in case the pump is too strong and the total systems turnover per hour is too large.
Thanks for the help everyone
