Hhheeellppp!!

[t's tank]

I'm a new hobbiest and have only had my tank since November. I have 2 clown fish, yellow tang, and orange spotted goby and several corals, but nothing major so far. I perform a 10% water change everything week and my local fish retailer tested my water and it's fine, but my corals, mushrooms, leathers, etc. are dying!!!
What else could it be??????

What lighting do you have?Have you tested ALL parameters?Corals need stable alk/DKH,PH,Calcium,SG.and no Amm,CO2 0r CO3.What is the temp.?WELCOME TO SWF.COM!

 

[t's tank]

I have 2 HALIDE lights as well as 2 flores. lights. An excal. protein skimmer and 2 jets. That's it. Temp stays around 78.7 - 79.2

it seems that your tank its not mature enough, lights, calcium etc
i recomend u allow the system go a bit longer before u add more to it.

Are the flourescent lights VHO actinics?Or just regular NO bulbs?How long has your tank been set up?Can you please post some water parameters..then maybe we can help.Are you using RO/DI water..or tap?

I have 2 VHO blue lights and 2 High power Halide white lights. Run both 8 hours a day. Salinity was at 1.027 last night (the first time it has ever been tested) and now at 1.023. I went to a new fish store and the owner gave me a few tips. He tested the water for everything and said it was fine except my PH was a little low. Today 2 corals (green gonapor and leather) died and had to remove them from from the tank. The green gonapor had and AWFUL smell. Is that common.?

Your salinity went from 1.027 to 1.023 overnight? That may have something to do with your corals not doing so well.

I run actinics for 12 hours,and halides for 10.
Making sudden changes such as dropping salinity 4 points overnight is not good,it should be done gradually so everything in your tank has a chance to adjust.Constant low ph is not tolerated by coral...did you happen to test your cal. or alk/dkh?
Yes it is common for corals to smell terrible when they die.Xenia is the worst I have encountered so far
Is there any way that anything foreign could have come in contact with your tank?Overspray from chemicals,bug spray,room deodorizer,cleaners???Anyone using nail polish..or anything else on their hands?Has this tank ever been used for FW,or is there any way copper could have been introduced to the tank???
