green star polyps and pump

[kafawa]

I have a green start polyps that has not come out in about 2 weeks. Is it dead? Should I take it out of my tank immediatly. I asked my local pet store and they said it might need to be in more current. I had a sponge on my filter becasue previously an annenome got sucked up in it. I took the filter off and and just put a spnge around the top part of it. Can anyone recommend a good filter that wont suck up anemones?

First off, test your water and let us know what your parameters are, Green star polyps are really hardy and if they are not opening, its probably not just lack of flow, theres probably something off in your water

For one thing green star polyps like lots of current. I have had them just up and stop opening for a period of about 10 days already when the water parameters were perfect and threlocation had not changed in a long time and it too was fine in regards to current. Sometimes I think some if not all corals go through a period of "hibernation" or dormancy for reasons only known to them.

My nitrates are really high. How do I lower them? I did a huge water change...still nothing.

the only way to lower nitrates is to do a water change. if you do a 50% change it will cut nitrates from 80 to 40ppm or whatever.
keeping them in check is a different story. there is a reason that they are high, and you need to find out why that is. then change whatever needs changed.
how high are they?

What kind of substrate and filtration are you using?
How much and how often are you doing water changes now?
