Great looking rock. :thumbsup: You'll have plenty to work with there!! Are you planning on cycling the snot out of it or dosing lanthanum chloride to minimize PO4?
My research has shown that the Marco is not known to leach phosphates and has a really great track record. What I plan to do is have rock/plumbing in place and then run on both closed loops and test phosphates out after a couple days. If PO4 is climbing I'll pump up to a bucket above tank with LaCl and a sock and keep at that until PO4 tests out well. Once it's good I'll add sand and open up the overflows to allow the whole system to be tied together!
Just finished up the rest of the closed loop plumbing and headed to monthly INDMAS meeting!
Once I'm back working on it I have:
1) Drain from tank to skimmer (2 X 1.5" drains feeding to a 2" input on skimmer)
2) 2" Drain from skimmer to sump
3) Emergency drain (2 X 1.5" drains feeding to a 2" pipe that runs to sump)
I'm designing so I can easily drain skimmer and shut off flow to it should I have pump maintenance or need to clean skimmer. Also after the above is done my next priorities are:
1) Getting Aquascaping figured out
2) Designing closed loop loc-line in tank around aquascaping
3) Building a tray to take in two 2" pipes and 2-3 4" filter socks for LaCl filtering
Hopefully I can have most of all the above done in next couple of weeks!?!?!?!:dance:
