[morino]

hi i am new i am writting from croatia in begining sorry for bed english.
I want to build a tank 74x31,4x23,6 an i am going to use a 12 mm or in EES 1/2 FLOAT GLASS i am planing to make a cross conection on the top of aquarium and in the bottom.
planing to use a two 7800l/h pumps for return from sump (in begining only one) and a 4x80 aqua connect lumimaster in begining then later to ad one or two more.

what do you think of a glass tickness and will it be strong enough?
and want to ask what bulkhead size would you put in overflow for return and what for a water drop in sump?

hi morino
im going to build 1500l aquarium 250x95x70 with 12mm Builder sad that it will be enough.I dont think you need two pumps for return.it will be to much flow.use one for return and one for closed loops.for one pump you can use 2x25mm,and return depens what kind of pump you have.
My english isnt good to im from poland.
