my polyps look bad (shrinking up)why?

[bojik]

eek the aptaisa needs to go. Cool you have the coral on the glass though . The ones that are open look ok. But that could change. Remove the aptaisa and try adding some strontium/ trace minerals to the tank. (if you do not already) IN addition to getting that ammonia and copper gone.

yea it was cool until now,it us to cover 3/4 of the glass.

start with getting a quarintine tank to put your corals and fish.then i would get new crushed coral for your substrate then do a complete water change and cycle tank all over,i think you have a serious problem. :help:

Before you do anything drastic, do two things. Get the readings double checked at an LFS. What test kit do you use? Many are quite inaccurate.
Second, get a polyfilter and put it in your system.
Do you use tap water? Also check the copper in newly mixed saltwater using RO water.

I have a salt water master liquid test kit,and marine lab test kit,I also use tap water that is ran through my reverse osmosis filter.

I would check things like copper with a better test kit. Or go to the store, get distilled water, and test that. Use that as a "0." The values you see may be test errors. It is imperative to figure that out.
