Jim,
Corals in the ick tank will be just fine with regular water changes. Continue to feed the tank to maintain bacteria, and, yes, imo, feed slightly less.
If you are going to do the hyposalinity treatment, you ABSOLUTELY need a refractometer to make sure salinity stays at the recommended level. I got mine from J&L, but AI might have them too. Follow the instructions from the hypo link to the letter. You need to keep an eye on salinity (twice daily, or more often, imo), as well as pH and alk with low salinity. Also watch for ammonia spikes as you lower salinity and afterwards. Do weekly water changes and clean your media weekly, or more often if you're getting ammonia. RC is a good place to find out about doing hyposalinity with your lion if you have any questions or doubts.
Have just done the major clean on the H-tank. What a lot of crud stuck in the powerheads and AC filtration systems
Broke down all PHs and ACs and cleaned them in outgoing changewater. Managed to break the heater while I was at it
At least the tank looked pretty clean until I added another bunch of dried food. Next time I add dry stuff, I'm going to soak it in SW before putting it in the tank so it doesn't get sucked up into the ACs.
Geez, I HATE ick and having to do all this cr*p to get rid of it
I've been adding about 10 drops of Garlic Xtreme to the PE mysis my ick fish have been eating for the past three days. I'm still hoping the garlic will be all I need to use, but am not counting on it. Will know within a week or two if it works, but will not be satisfied that garlic works until the fish are ick-free for a full six weeks.
