Aw jeez

I hope you get things under control easily

Oh crap. That's terrible. AEFW don't affect all SPS, just Acros, so that's about the best news you're going to get out of this. (sigh)

If you're wiping it down that much, then there is obviously nutrients within the system, so if you continue with your coral feedings in the evenings it sounds like you're on the right track there.

Haha, I didn't remember who the comment was to, but I remember now. :)

If you're doing a 10% or 15% waterchange it really doesn't change the values within the tank very much. Just skip dosing calcium (but continue dosing alkalinity) for a day or two to allow the value to drop.

Well I feel really silly. I ripped my tank apart and now it looks like a frag tank. Pretty much all the large rocks are outside baking in the sun. OH well, at least I can rebuild a nice bonsai tree like everyone else.

All colonies were pulled and mounted on travertine tiles. I haven't found any AEFW at all, nor any eggs. I must have confused and misidentified it with rotifiers or copepods? I saw two creatures jump out of the coral when it was in an iodine dip and die. Can flat worms run around really fast? yah!!!!!!

I believe the issue was not due to water quality but actually due to low alkalinity. I replaced the regent and it was way off. I'm hoping to run my ALK much higher now at about 9dKH to ensure I don't have these issues anymore. I'm assuming with the ALK at 6.2 dKH, the tips got burnt and the STN started.

I'm going to put all 6 banks on 6500K and just grow the coral out. Once they are large enough, i'll focus on coloring them up.

I actually wipe it down daily only to prevent it from building up into coralline algae. I hate that stuff. Sounds strange but true. Anytime I see it on the glass (including floor), I scrape it up. I don't mind it on the rocks, but would prefer if the rocks stayed white looking.

Also, wiping daily involves a simple sponge and it's a 2 minute job. If I left it to build a film up, it takes longer to scrub.

AEFW are pretty big (like average 1/2" or so), other flatworms can be much smaller. All flatworms move pretty fast, but not like pods or rots.

What are you using to test alkalinity? Maybe you said it already...I will go look through your thread again.

EDIT: Ah, Hanna Checker. You experienced a big difference with new reagents? That's not comforting. Do you know anyone with an Elos kit within expiry that could double check for you? Salifert reads about 1 dKH high.

Can low alkalinity burn tips? Mostly it is high alkalinity. Before I started dosing my alkalinity was often low, even lower than 6 and it never burnt any tips in my sps.

Burnt tips and STN are probably 2 different problems and that they happen at the same time probably means that there is something quite out of wack with your system, not sure what.

I was thinking the same thing, but OP wants to experiment. :p

Probiotics with a kH over 8.2 is just asking for it. Leave it between 7.0 and 8.0.

Albert, I assume you're referring to this:

Just to elaborate for OP, it's not not the bacteria, but the carbon source. Using a carbon source with higher alkalinity will often cause STN or even RTN. Albert might be onto something though, did your STN and burned tips show up during your vodka dosing or before that or after that?
