Eye health good for Coral Health
 

So I just came back from getting my new glasses and lets just say a whole new world of exciting things opened up.

I bought a tank shutdown from a customer of mine a few months back and with it came a very weird hammer coral. This hammer coral had weird purple spots that resembled coraline algae, that is what the seller even told me it was.

Now that I am armed with my new glasses, my frag tank was now in HD. And my mystery purple coraline spots turned out to be a massive flatworm infestation. Having spread from the initial hammer coral to the adjoining mushrooms.

So armed with a fresh water dip it appears I'm hopefully on the way to taming this newly "eye opening" pest.

Suck them them all out the. Time for some flatworm exit

Does a FW dip actually work for these when they are on the coral? How 'healthy' does the coral have to be?

I just ordered some FW Exit, intending to use as a dip, but if I can use FW that would be even better.

Does the FW need to be RO/DI or will treated tap water also work?
