Wow!!!!!!
Don't mean to step on any toes here, but I smell disaster on the horizon as SW65galma and others have stated.....
First the guy who's selling or putting this system together for you needs some help....I'd like to see some other systems he's put together for people and see the progress of the tanks before I'd let him put my next system together for me....Sorry don't mean to be rude, but some of the choices are very odd
I'm building a custom 240 along with a dedicated fishroom so alot of time and thinking is going into my current system.....My tank is custom built with Low E glass and has a center overflow with 3 1 1/2" bulkheads which will drain into a 205 gallon custom acrylic sump built by myself, and the tank is eurobraced and drilled to allow easy plumbing of the OceanMotions so I don't have stuff draping over the top of the tank.....and the tank is drilled for CL with 2" drains as well
The first major problem I see with the setup is that no where is there any listing of an RO/DI unit anywhere......All tanks need this and IMO is a definte requirment before a silly UV sterilizer....So what you have a sterilizer, but your water quality from the start and all water changes could be crap so your UV sterilizer isn't going to do crap for your system.....That is one of the last pieces of equipment I would be spending money on at this point......
Lighting is questionable as well.....with a depth of 3'I would go with 400w MH if using SE bulbs and might get away with DE 250w Mh......But personally I would opt for the 400w MH depending what your planning to keep in the tank, but with that depth you'd be better suited with the 400w MH, your VHO are basically used for supplemental lighting.......
Choice of pumps is very poor.....A Mag Drive 18 won't even ripple to top of the tank
You need to look at pumps alittle closer and come up with a turnover rate for several reasons.....How does this guy even know what flow will go through the overflow then into the custom sump being built etc....??????
Why not look at the Sequence pump lines and I'm more than positive you will be much better suited with an external quality pump....Not saying MD are bad just they aren't for this setup....If you have tons of money why not check out Red Dragons.......
Don't see anything in your custom build or setup as far as supplemental flow inside the tank....You can't rely totally on the sump and return for all your water movement in the tank....You will need to supplement it with something such as an OM, Wavebox, powerheads or such....With the money spent and holes drilled IMO it would be better redesigned to incorporate something for a CL(closed loop) for this tank.......
Skimmer choices seems very poor....I'm not saying running 2 skimmers is a bad idea with alternating cleaning times, so 1 is pulling while the other is coming back up and so...., but don't think skimmer choice is good at all.....Why not look at ASM, EuroReef, Deltec, Bubble King, or if you want raw skimming power look at a Beckett skimmer such as MRC, Barrs, and I forgot to mention ETSS as well.....
Sorry to be rude but your headed for disappointment and disaster with the setup and equipment choices and you'll see shortly that you'll be replacing and spending double the money and tons of junk laying around the garage when things start to come apart on you.......
I also didn't see any mention of any test kits at all????? What is this guy selling you and putting together for you???????
