Kaiser November 19, 2022 Share November 19, 2022 Need advice guys I have 40g tank over year old , had few sps, hammers, torce and other stoney corals , I put them with my other soft corals like lots of johas, gsp, keintree gonipora few mushrooms and other soft corals ,, one by one all my Stoney corals died but where all my soft corals thrives,,, what is reason dying my Stoney corals I used to change water every week and all my perimeters were within range So please pro guys what could be the reason not having lack with Stoney corals !!

jhOU November 19, 2022 Share November 19, 2022 sps are generally much more sensitive than lps and softies. Stability is key, not just hitting specific parameter numbers. To narrow down the issues, tell us a little more about your tank. Lighting, flow, dosing, actual parameter numbers, testing routine, ect… pictures are also very helpful. There are a ton of variables with sps success. Link to comment Share on other sites More sharing options...
DaJMasta November 19, 2022 Share November 19, 2022 Flow, temperature, or lighting if inadequate could cause issues even when water chemistry is normal. It's also worth double checking your water with another set of kits (maybe get a LFS to check too), it's possible for kit reagents to go bad and read off of what they should, or your refractometer to drift away from where it should be and leave you with the wrong salinity. Do you have Acros, or other SPS? There are some leather corals that release chemicals into the water that can poison acropora. Link to comment Share on other sites More sharing options...
JJKK November 19, 2022 Share November 19, 2022 I have had similar experience a few years back. Did an ICP test to find out that I had high Tin in my water. Torches, hammers, softies were all fine, but the SPS were STNing. If you have stable acceptable general parameters, I would do an ICP test. Good luck. It can be frustrating. But it can be figured out and addressed. Link to comment Share on other sites More sharing options...

I have tow kessil 360x used runs 12h due to hair elgae now running 8h , have tow flow power head all over my tank getting flow modaretly , I dose 700ml kalkwasser daily (2 spoon with 2g water mix)Just checked my water peramiter Ph 8.02Phos - 08Salinity-35Cal- 500Alk- 9Meg -1430Nit- 4Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
DaJMasta November 21, 2022 Share November 21, 2022 Where were the corals in the scape? From the extension of the zoas, it's probably not so bright in the lower half, though that goni in the center looks pretty happy. Parameters wise it seems generally good, a little high on the magnesium and calcium side, but not problematically so, and the goni, fungia, candy cane, etc. are stony corals that seem to be doing well, so I don't think it's a skeleton-forming-chemistry thing. My guess is light intensity and flow. A breeze on the corals you have will be on the low side for an acro, and there are spots in the scape that probably get a lot less than that. and with the light situation maybe the best spots would be sort of centered under each light, at least mid tank high, otherwise if the lights are down at all, you could likely increase them slowly (less than a percent a day) and not %$#* off too much of what you've got, and then get something sps and give it a try in a higher light and flow area.

Origami November 22, 2022 Share November 22, 2022 Are you running granular activated coral (GAC) in your system. Any chance you're seeing signs of coral chemical warfare (allelopathy) - in this case, the release of chemical toxins from the soft corals affecting your hard corals?GAC can help capture and remove these chemicals from the closed aquarium system.

BowieReefer84 November 22, 2022 Share November 22, 2022 It kinda looks like you have an African Flameback Angel in there, but it's only yellow on the face. What fish do you have? Some (like the flameback) nip at SPS. There is a big difference in difficulty b/t SPS. Monti are pretty easy, where as imo acropora are much harder to keep. I do think if they were monti that died it was either chemical warfare or nipping fish assuming parameters are pretty stable and everything else is looking good.

The angle is good never saw nipping on my any corals Not sure why probably me being newbi that’s why all my acropora montipora died I’m taking time learning more and try to stability my water perameters Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
