KrazyKuch's & Michika's 180Gal Tank Build

[michika]

I'm hoping by the time we find a house and move I will be done with the cheap salt we bought to kick this tank off. We used Reef Crystals to start this system and its just driving me nuts. After a water change it takes me 2 weeks to get my levels back up to where I like them, and then its time for another WC and I have to start all over again.

Post water change I'm seeing;
dKH 5-6
Ca 340-350
Mag 1100 -1170.

Pre water change levels that I am barely hitting are:
dKH 7-8
Ca 380-420
Mag 1250-1300

I just get so close to my optimal levels, and you can see it in the tank too. The moment I hit the right numbers I can see the SPS take off, and I can see the colours start to change and brighten up in a few pieces. Then as soon as the levels drop again the brightening fades, and I stop seeing growth.
