SPS Reef tank help

salty01 · Jun 23, 2016

I have an SPS reef tank that's about a-year-old and I'm having a lot of difficulties. As of lately the corals don't look good at all,bleaching tips and bases and all-around no polyp extension.I've made a quick video to show you my systems parameters and to get you familiar with the tank please take a look and give me your opinion. I appreciate it. I think the videos compressed, the quality might not be good I apologize.

Had simular problems awhile back and it turned out i had some unwanted heavy metals along with an "reef safe impeller" that rusted. So my advice would be to do some big water changes every other day to level out any possible pollution to the water, double check all your equipment so that there no possible failure or pollution from it.

What a beautiful video and tank. Have you checked for critter?

Your system looks clean, nice job. Unfortunately this some times happens when your doing everything right. Your alk is lower than most but i don't think 7.5 is an issue as i have ran sps tanks at 7 for years and did well. Your phos are pretty low, your feeding alot of supplements as well and one of them could be causing issue's. I would test for leaky voltage as it may be high, and like mentioned above, check equipment for rust. I saw a hanah calc tester, have you used anything different to test your calc? As well as alk?

How long have Sps been in tank? Where those grown in your tank or recent purchases of Sps

Beautiful setup. All very technical. Have you considered simplifying things some? As in some very large water changes, replace all your RODI filters, calibrate your TDS meters and refractometers. Fresh batch of salt, and just do some really big water changes in sequence. As mentioned check for stray voltage and broken impellers. But maybe consider dipping everything or even going SPS fallow for a couple months and just keep the fish fed and re-introduce them after things stabilize. I don't know what it is, and you're seemingly doing everything right...but every time I've had a crash, or know someone who has had a crash and lost a significant portion of SPS, going back to basics seems to do the trick

No3 at 0.03 and Po4 at 0.0................. no wonder.
For how long is this?

Id say your alk to Calcium ratio is a little off , but that shouldn't kill them like that
also maybe your stripping water to clean Corals need some phosphates IMO

update: I was on a trip this this weekend I turned off the UV sterilizer and turned down the Phosphate minus and carbon,turned off ZEO stones completely I plan on doing this until I have some phosphate and a little nitrate and I'm a trying to try to keep this stable.already I have noticed polyp extensions on Birdsnest. Oh and I've been feeding and feeding.
