the first 45 are going in as we speak, there are 3x 45 gal mixing at the time, so I'm lowering my water in the tank to about what i think would be 160 to 180 gal and than fil it while all pumps are running.

total water volume inclouding new frag tank and sump would be 500 gal - rock and sand, so about 400 / 430 gal water vol

when I have the first big change dun, i'm hoping to get down to about a KH of 20 and then bumb the calcium up a bit to 460 and then let nature do the rest

I drop about 8 to 9 ppm on the calcium a day, and if I recal right about 1.6 KH a day, so then we should be back in check after a week

gust hoping everything is doing ok

I stil have the frags (about 130) in smal bins, and wil put them floating in the new frag tank for tonight, and tomorrow while dripping the bins, introduce them to the new water parameters (I dont want to loos them)

ahhh, all the water is in and everything is running, I still cant se a thing, so lets hope overnight everything stabelises a bit, and I hope to mesure something close to the 20KH



onlything I see is lots of white that fel down on everything like snow.



I will keep you all informed tomorrow, I'm dun

Sincerely hoping you wake up to a lively healthy tank this morning!
My stomach is flopping just thinking about the whole ordeal

Man my stress level would be through the roof I hope this works for you. Lucky AND unlucky you having that kind of volume to play with...

little update:

tank is locking like a snow stom hit it.

coralsproduced lots of slime, but so far, untill the lights go on I dont know how thy do.

I still se some polyp extention on my SPS so hope this is a good sighn.

mesured my KH yesterday about 3 ore 4 times, and each time it was around a KH of 30 to 33

today, after the 180 gal water change (tap water and prime) my KH droped back to a KH of 11.8 to 12

the calcium is slightly over normal at 550, but also this will settle.

overall the tank had its shock of KH for about 4.5 to 5 hour

I will check my magnesium as well later today, as I asume this one droped a fair bit, as instant ocean is low in mag and it had 180 gal

I will also put some pictures up later today, when I have everything cleaned up and the lights are running
