Ok I'll try and answer all the questions to give you the best idea of what's going on. First my beautiful wife went ahead and got me my new main tank....I wanted the 100 gal
but she found a deal and got me a nice 45 gal
one (21 1/4" X 21 1/4" X 23 1/2", its a giant cube...not bad for $30...included the stand). I hadn't planned on useing an overflow to get the water out of the tank, mainly cause I'd hate to cut or drill any part of my tanks if I ever want to upgrade them and resell. Instead I plan on using a suction method (my current power filter gave me the idea). The inlet will have a screened filter to let most everything in...but will also be surrounded by bits of live rock enough to keep my shrimp out of it and hidden behind a large wall of live rock.
The reason I'm using the power filter is actually 3 fold. 1) if large particles gets into the sump this should help filter those out...plus it's easier to clean this out. 2) My main heating piece attaches to the power filter so I won't have to show people my ugly heater...which by the way is 150 watt (I know it's small but I have a secondary 100 watt heater I plan on placing somewhere else later.). 3) it will give me a great place to add my chems if I can get them to regulate correctly.
I'm using a live sand/live rock with crushed coral for the only reason in that when I first started with SW
tanks my wife liked how the crushed coral looked....so I figure it's better to reuse it then get rid of it.
I am trying to avoid the use of a skimmer...mostly for the fact of the price of most of them. Also I can avoid the use of the filter floss as long as none of the little "bugs" will jam up the pump.
I want to try and keep the flow rate between 10x to 15x....I'm hopeing to keep 2/3 of that coming from the sump and 1/3 through a wave maker.
Finally I'm not sure if this matters or not but I'm thinking of going with 1" tubing...but I may lower that to 3/4" but no lower for both the inlet and out flow pipeing.
Finally over the weekend I had an idea of how to do my return without putting holes in my tank. I have an old powerfilter used for my old 10 FW
tank (hasn't been used in about a year). So I was thinking of removing the power piece at the bottom and attaching my return hose....thus the watter would flow out through there. Just another idea...
Thanks again to everyone,
