SPS stopped growing following produce change

[Ds04384]

Hello everyone,

I had been dosing fusion 1 & 2 but decided to switch to the BRS two part to save money. Since I changed, my levels have remained very close to what they were with fusion but my SPS have dramatically decreased in growth or stopped all together. Some may also be showing some slight STN. Anyone ever have something like this happen or know what may be going on?

I have read a few times that this can happen when the type of calcium/alk supplement changes. Basically they are use to one chemical and now are adjusting to the other. Kinda like changing the lights when they are used to another. Of course that's if nothing else has changed in your tank.... just brainstorming of course

Fusion also has some other trace elements that your corals are no longer getting with the BRS supplements
