Coral problem

[Ivo]

All corals in my tank die except the one in attached picture. Water parameters are OK. Fish are OK. Anyone has experience with these species?

Not to burst your bubble anymore than it already is, most consider these a pest nem and strive to get them out of their tanks. I'm curious of the reason why all your corals are dieing. Can you give more specifics about your tank?

 

[DustinReefer]

What is "ok"? Can you post detail on param? Lighting? Tank age? RODI water TDS? Those pictured are Aiptastia, major pest and it looks as if you have quite a few :/ some have had luck with Aipastia-X, Peppermint Shrimp, Berghia Nudibranch for control.

+1 to the Aiptasia, it's such a nuisance.

Tank is 49 gallon. Ammonia less than .25. Nitrate 5.0. Calcium 440. Salinity 35. One bad parameter is kth 4... See picture dying corals.

That low of kh seems to defiantly be the problem. Low kh low cal and low mag. Will cause you loose coral fast. And your ammonia should be undetectable. I'd say your ammonia and kh are why your corals are dying.

What type of lighting are you using? How long has this been setup?

 

[Kershaw]

Tell us about the age of your tank?
And what you do on a weekly , biweekly or monthly basis to maintain it.

 

[Ivo]

What type of lighting are you using? How long has this been setup?

Led lighting. Aquarium is set up for 2 years

 

[Ivo]

What type of lighting are you using? How long has this been setup?

Every 2 weeks replace 15% water. Have also a skimmer

But calcium seems to be OK..?

 

[Duke4Life]

Tested for phosphates?

 

[Kershaw]

Yes calcium is good.

 

[Kershaw]

What kind of salt are you using. And are you dosing anything? What kind of water?

 

[Ivo]

Yes calcium is good.

Yes .25

 

[Ivo]

I use ready made water from shop

 

[Kershaw]

Try testing that water.

 

[mikekarabin]

I just started making my own it's a bit of an it's a bit of an investment but the quality of the salt is much better.

I am still wondering why, there is ammonia in a 2 year old tank.... My current tank is less then a year old. And I can't get an ammonia reading since it cycled
