The WEIRDEST thing.......

[ReeferRob]

Rob,

This is what my approach would be.

Make salt water from ESV and test the water - test alk , calc, megnesium

Make salt water from old salt and test and test the water - test alk , cal and megnesium

And compare them.

I dont think light is an issue, but lps do react to rapid/fast alk changes. But I would guess your acans should react before the frogspwans react.

BTW did I hear orange hammer - Pics plz

I would normally agree with you Manoj, but I started 4+ weeks ago on both systems and this is the first sign of any stress.
Plus I would expect my SPS and clams to show signs first if there were alk or calc issues.
Everything is really happy and healthy but the two euphys.

As for the Orange Hammer, well I got had on that one. Only shows orange and gold under actinic. Full light is more tan. But thats what ya get for buying sit unseen. Still like it though!!

Is the Coral Rx in this tank or in a tank connected to this one?

Not sure I am following Tom. Coral Rx is a dip or treatment. I do use it for new incoming corals to either system. Grow out and Display are separate systems.

I thought you've been treating algae on frags using Coral Rx, and was wondering if this treatment was somehow affecting the Euphys. If it's a dip then that's pretty unlikely. Especially if it's being used in the other system!

LOL, got cha now Tom. Good thoughts though! Yes I am treating some HA frags but that has been in the grow out tank.
I've been dipping them and then rinsing thoroughly before placing back in the system.

On another note, I looked at the tank last night after the Wings game and didn't see anything out of the ordinary going on. I woke up again at 4 am and again no changes.

OK my next thought is lighting. My Euphy. polyps tend to get smaller when a bulb needs to be replaced. I know yours aren't smaller their closed but it still could be the culprit. I have bulb replacement staggered so only one at a time needs to be replaced but if all of your bulbs need to be replaced the affect on the corals may be more pronounced. Once a bulb reaches the 9-10 month range on my tank it's day is done. If you're overdriving your bulbs and/or have a longer photoperiod your bulbs would age more quickly. If possible I'd try switching the bulbs sooner and see if that takes care of the "weirdness".

HTH,
Tom

I was thinking of doing the same thing Tom. I'm gonna start switching out bulbs tomorrow. And do a bulb every 5 or 6 days. I just getting to 9 months.
