Almost done with the drains still have to add rock to the top of the drain this should be the perfect angle.. I water tested in last night and the water level was perfect..
I use portland #3 cement, crushed coral, aragonite sand and about abig ziplock bag full of the pvc shreads from cutting all the plumbing on the last 2 builds last month.. The pvc shread's will make the coraline coverage a lot faster, aragocrete cover's in coraline faster the regular rock anyway.
Yes, Russ that is the box for my whole condo it's only 3 bedroom's.. A building also. I'm thinking about changing the whole box I will be adding 2 more breakers just for the tank this time around for now.. Also this is the bucket of cement, pvc shreads, crushe dcoral, and aragonite sand before water hits it.. Oh yeah there is one more secret ingredient:tongue1:
