Core 7? Never again

I have a 3 year old sps tank, which was doing extremely well. Was dosing Bionic Ca/Alk/Mg. Decided to switch to Triton's Core 7 "other methods" and in a few weeks corals took a big dive to worse.

Monitored alk closely after the switch and slowly brought it down from 8.6 to 8.0 dkh. All parts were being dosed equally and I folowed the intructions as required.

Out of around 35 colonies, some of which ive had for many years, lost about 20.
As I noticed polyps not opening, loss of colors among other issues, I checked all other variables and everything remained the same as when the tank was thriving.

That was a big lesson for not changing things when It is all doing well.
From now on, back to basic dosing, proven methods, 10% water changes bi-weekly with a good salt.

Today hooked up the old dosing containers, and did a large water change. Will do another one tomorrow and keep stress off the tank. Hoping to get the remaining colonies to bounce back to what they were!
