Alright its now the morning, and it's still in the same shape-It looked so much better in my display tank I kinda regret treating it. Anyway I accidently turned off my RO last night, can I just use de-chrlorinated tap in the mean time?
I think you are absolutely wrong.
In order not to stress the anemone, the water need to be match, aged water. Match in bothe
TEMP and salinity. This mean you have to warm the newly mixed water or use DT water which I use.
If you water is not matched with tank water, then you stress the anemone changing from on environment to another. However, sick Gigantea will not live without treatment. Rather than "regret treating it", you should regret not treating it sooner. I cannot stressed enough regarding the need to start treatmetn early.
Make sure that you match the water you use in changing the HT water. I cannot stress enough that the DT need to be in great condition, warm, good circulation, remove waste and if the anemone discharge in HT, you need to do water change. When ever you do water change, you need to replace antibiotic.
I use DT water to change and not have to worry about heating it up. When I do water change or whatever reason, I do 100% water change and redose full dose of medication.
Good luck with him.
