Hi, Building a 65g FOWLR
...that I'm almost certain will eventually become a reef...but I so love the fish...LOL
Anyway, finishing up the plumbing side of the mechanics - incorporated a Glass-Holes 700 kit for the return, will DIY a 20g sump/fuge, utilizing a Supreme MD7 pump. The return has been drilled for 3/4" bulkhead.
All the plumbing is completed, save for whatever I use from the inside of the tank at the return bulkhead - to verify the plumbing is sound (no leaks), the sump will hold the overflow when power is out, the MD7 works, etc., I'm using a 75 cent 3/4" elbow from Home Depot. All is good. No leaks. Sump (baffles not yet installed) has room to spare.
regarding the return (inside the tank from bulkhead)
. It was suggested to me at the LFS
that I utilize loc-line... and I thought I would add a "Y" so to encourage better circulation. BUT, as the loc-line is expensive (approx. $25 for 12" of plastic pipe!), I'm wondering if there is a more cost-effective alternative that will get the job done? For instance, just keep the 75 cent elbow that shoots straight down into tank or whatever?
I am planning to augment the circulation with power heads, as needed. So it's not clear to me that the $25 worth of loc-line is money well spent.
