Froggie,
Knowing what your water parameter is basic, knowing what water chemistry is, now that’s technical, but that’s just my opinion.
Does it not concern you that your LPS slime when you do a partial water change, that’s not normal at all for any coral?
When corals slim, molt, shrink-up or close-up it’s a defense mechanism which means that something is bothering and or irritating them, which causes stress to the corals which is not normal, and you say slimming happens with each water change.
I personally never saw a coral slime after a water change.
Has anyone else here at MR experience coral sliming when they do water changes?
Froggie you will sooner or later end up with a bigger tank, remember bad habits die hard, good habits last for ever. Just some FYI for you - Garry
Thx for the advice

I do have test kits,
Saliferts and other complete "sets." However, I dont test much. I used to be very obsessive with my nitrate levels, alk, and calcium levels. It's not that I dont know water parameters, I choose not to rely on them and rather, guage my tank's health by my coral's health and growth.
THe only thing I test for every now and then is my pH level. The product I use Chemi-pure does a good job at keeping my pH in the 8.2 range. I test it every 3 or 4 months to know when to swap out the chemi-pure for a new one. I know my nitrates level are high when my I get some brown di
atoms on my GSP mat. I know when my Alk levels are out of whack when my Xenias look funny. ETC.
Its only then that I test. I don't test on a schedule basis...I test when see signs of trouble. As a result of my "ri
sky" methodologies, I keep mostly soft corals or rather, ones that are considered hardy.
Furthermore, I expose my corals when I do a water change which might cause them to slime up slightly.
Remember 2g water change is roughly 25-30% for me, so a my partial water change isn't so partial...it's actually a good chunk of total water volume.
With a 2000g system, 25g water change is nothing for your system. If I had a system of that size with all the investment I've put in (you're in the business of propagationg corals too), I would test more often...but right now, why worry myself? I let my reef do it's thing and I sit back and relax and take in the box of water in front of me
