That's going to be a lot of flow! Very good, just make sure that you aren't blowing corals off the rocks and your fish aren't cowering in the corner.

I use a Hydor 2, 3 & 4 in my 150 with a Mag 12 as a return for flow, and I have about a 25X turnover rate. You'll have something closer to 40X!!! But if you use one high and one low you will get a good current throughout the tank.

I can't wait till you add sand and rock!

yeah, I figured on 40x with the 2 together, but I will adjust them to make sure nothing is getting blown out of the tank....LOL
salt reading is 1.024, so have added the sand, pretty cloudy for the moment, will post a pic later, once I can see it better, nice feeling sand though.
does it matter whether I add the dry rock first or the live rock? is there any specific order?
I would like to add the dry rock, about 35 lbs of it, mixed with about 15 lbs of cured live rock, then later this week add another 25 lbs of cured live rock, would this be ok??
PS protein skimmer will be hooked up monday or tuesday.

This will be fine. You might (or might not) see a second diatom bloom a few weeks after you add the second batch of Live Rock. Just keep an eye on Trites and Ammonia after you add the second batch just in case you have any die-off.

will definately wait until all readings are clear, after both additions, not in a rush to transfer the fish yet :)
still have to pick up that alkalinity test kit, will be some time this week as well, Since I decided on a less than 1" sand bed, how much live rock do you figure? I was thinking around 85- 90 lbs total ?

TerryAnn,

My gut is that you are not planning for the amount of rock you will probably want. Plan closer to 110 pounds, and stop adding rock when you feel the visual appeal of the tank is what you are looking for. I'd rather you aim high than low.

A lot depends on the density and porosity of the rock you purchase. Some rock is simply lighter weight than other rocks of similar size, so the end result in terms of pounds could vary greatly.

I agree, I will most likely want more, but my question is, for a start, with 85 lbs of rock, once the tank is ready, can I safely add fish and continue adding cured live rock after the fish have been added?
Most definitely, you can. No problems at all. This is getting fun! I find myself looking up your thread first every day now, waiting for new pics. So.... you have to keep posting pics! ;-)
