Ok...here is what I am wanting to do. I have several tanks. Most of which are FW
and I've been given permission by my wife to cut a hole in our living room wall and put a new SW
tank in it. (how excited do you think I am?) So heres the deal. I'm getting a 75g (unless I can get ahold of a 90 or 120 that is 4' long) and that is what is going where I currently have a 55g FW
tank. The difference being I'm going to have a hole in the wall where the back of the 55 is for the new tank to show through into the living room. I custom built a wall type stand that has the 55 and 2 10s on it. Anyway that face the 72g reef tank I have. So basically I have a hall of fish. What I need the pumps for is to move water out of the sump that will be under the new tank over to the 72g tanks sump and skimmer and then pump it back over to the new tanks sump so it can circulate in that tank. These 2 pumps will share the water between the tanks but not acutally be part of the "flow" of either tank. I would do it below the tanks but the problem is I'm on a slab here and can't cut into it to run plumbing so I have to go above the tanks and across the celing and over to the other tank. A total run of about 20 feet including the up and down distance.
So..that is why I need a pump that can go straight up 7 feet and still have enough to get the water over 10 feet and allow it to fall back down about 7 feet....
This of course is still up in the air but I would like to combine the systems because of the large fuge I have on the exsisting tank and the enourous skimmer I have for it.....more to come but need suggestions and ideas! Thanks
