Start off with 2 part or CaRx?

[ChrisQ0904]

I had to re start my 180g and now that I have only a few pieces of coral left I decided to redo a few things. One of them being CA and ALK supplement. I have some 2 part left over from before but I also purchased the CaRx and have that available.

Is it safe/suggested to start with the CaRx now or should I start with 2 part and transition over once the demand becomes greater?

I would start with 2 part. Once your tank is stable with alk/cal I would then transition to the calcium reactor.
