" am a little confused about what buffers to use and if I need reef builder as well. What other products should I be using like trace elements, or stronium Im still not sure on what is the best to use and add to my 24g reef tank. I Just want to make sure I am providing the corals what they need to be healthy. "
Most of us try to throw a lot of chemicals and foods and money at our tanks to start with and end up with a closest full of chemicals we never use. Most of the chemicals you can over dose and hurt much more then you are helping. I know I’ve said it before and perhaps some others will chime in and agree, “If you don’t test for it, don’t add it.” You don’t yet have a strontium kit so that should stay on the shelf. Sorry to say that most of the chemicals you have purchased… probably a waste of money.
“I also have a bak-pak 2r+ protien skimmer”
How often does the skimate cup fill up?
I have two clown fish I’ve had for three years, two more I’ve had for a year and about 50-60 more I’ve had for a couple hours.(new thread about that soon:-D )
Joe, “The Pineapple tree is non-photosynthetic right? I’d give that one away.”
I don’t believe they are entirely non-photosynthetic or impossible to keep. She probably has a better chance of keeping it alive then most of us actually. Not to sound sexist, but women are much better feeders then guys. You do have an extremely valid point though that the extra food for non-photosynthetic such as sun coral or deep water gorgonians, but… well another common name for Capnella Sp. is…. Kenya tree. This is a slightly different species then the common Kenya Tree we see most often, but very similar in care requirements as far as I understand.(and it is prettier to in my opinion)
Joe “but they also have to sell things to stay in business.” I have ALWAYS hated LFS and the advice they give. It is a shame too because trust me when I say any LFS can do very well suggesting people do the right thing for there tanks. People often don’t listen to me and say they don’t really need that expensive skimmer thing and then turn back to another LFS and buy chemicals… but they also often return later after finding the internet and realize I was right. If they don’t, they probably didn’t really care enough and won’t be in the hobby long anyways. I won’t jump on the soap box too much, but you can ask anyone I have helped out at the store, I usually talk people out of more then I talk them into. It is possible to get good advice at an LFS if you visit the right ones. 
THE PLAN:
Unfortunately, looking at the images of her tank today at the shop, leaving things alone and taking her hands out of the tank now would be worse then starting over and she would for sure lose everything. The zoanthids, and possibly mushroom, have been over run with a bacterial or protozoan infection most likely. I recommended using a coral dip under the max time(10min) with normal dosage. After the dosage they are to be placed back into the tank up off the sand and in slightly higher flow.(closer to current power heads and one additional power head will be added) If things didn’t dramatically change for the better in 48 hours she will repeat it again with twice the dosage(by package instructions). We also said that the corals would not be moved around too much, so they get a chance to settle. After that we will give them a while to improve and closely monitor and take things step by step. We also plan on dramatically cutting back on the feeding for time being, but spot feeding the Duncan 8 mysis for a little extra energy.
We came up with a short term plan(next 3-4 days) and a long run plan including careful feeding and a tank upgrade in the near future. Luckily this hobbyist didn’t simply get her information at just a plain old LFS and found us here at the DRC.
Keep us up to date!
Wow that was a long post. Hope I got everything.
