what size to drill

[yellowslayer13]

I am getting a 24'' 24'' 20'' a 50 gallon. What size return and drain should I drill.

my oceanic 50 i did everything from glass-holes.com.....contact them w/ a list of what you want & they'll make a custom order for ya & save ya a lil bit more $$$ on top of their pretty low prices already (& shipping is free on orders over $15)

for the sump overflow, i went w/ the 700gph overflow kit (http://www.glass-holes.com/product.sc?categoryId=3&productId=5) $65 for the overflow box, bulkhead w/ anti-siphon tube, glass drill & bulkhead

for the sump return, i went w/ (2) 3/4" loc-line return kits (http://www.glass-holes.com/product.sc?categoryId=27&productId=131) $23.99 for 1 or $38.98 for 2. includes section of loc-line, bulkhead, bulkhead -> loc-line adapter & glass drill bit

i did dual returns simply for asthetic reasons since i was mounting the overflow box in the middle of the upper back wall, so i did a return on each side....simple t-fitting on the return line from the sump pump

my closed-loop i went a bit overboard, but there was locic in my madness LOL .......

since the 1.5" overflow was center-mounted, i would have to mount the 1.5" CL overflow off to the side for the plumbing to clear, so why not just do (2)?!?!?! ....see method in the madness

well then i had 2 large CL overflows, so 2 small CL returns wouldn't be sufficient, so i ended up doing (4). doing (2) on each side also made it easier for the plumbing to clear the upper sump returns .....more method in my madness LOL
