How to get back in to sps after wipeout

[FishOkay]

So a little while a go I had quite a few pieces of sps corals, different montipora types, stylophora, birds nest and a couple of acropora and without warning over the course of a couple weeks they started to die it started with the stylophora and eventually they all died I couldn't really explain it at the time all parameters were okay I'd had some of the monitpora colonies for a couple years and had grown them from frags. Anyway after that it put me off sps other than the odd cheap frag from ebay which died again I don't know why. Its been atleast 4 or 5 months now and I really want to start adding sps again I'm looking at buying a montipora colony to start but I'm a bit worried itl just die.
If it was a pest or some sort of bacterial infection is 5 months enough time for whatever it was to be gone and is there anything I can do to check before adding another coral thatl just die?

Icp test. Do that first would be a sure fire way to check for anything alarming.

Yes test to see what the environment is like then continue

Yeah il make sure to do an icp test the only thing is at the time of them all dieing I did a couple icp tests and everything was always good so I can probably guess itl be the same again.

I have 2 kessil a500x above a 3ft cube 30" deep. Most of them I'd got from other reefers around the area and went to collect. A few were already colonies that they were selling but the frags were mostly from ebay to be fair.

Sounds like u have the equipment and sourced healthy stock.

Regardless I have had things go in the positive direction only to crash. Part of keeping sps especially acropora I guess
