I run the full battery of tests every Friday religiously and as always this Friday was no different every thing was fine. Well Monday I look at my tank at lunch and none of my green star polyps are out:whut: . Immediately I break out the tests and I have an ammonia spike:wow: so I start prepping water for a change and as I’m looking around my tank I see something in one of those hard to see back corners. As I’m staring at it my wife asks “what’s wrong you look like a concerned parent.” So I tell her then she starts looking and comments hey where’s the BTA? Sure enough that’s the purple black blob I’m looking at in the corner:cry: . It kills me to loose my BTA but those green star’s save my tank! So I siphon it out do a 20% and keep an eye on the tank. Hours later they are back out and happy. My point is indicator coral are GREAT!!!!!:mrgreen:

Yes, you are right. As hardy as they are overall they sure are fast to show a stress response.

Sorry about the anemone.

My Xenia is the same way, I can tell if my tank is running .5 of a degree hot with that guy in there.

interesting.. thanx for sharing

Well my tank is still suffering! Last night I saw a crab laying dead on some LR. The problem is I didn't put a crab in my tank! It must have been a hitch hiker. I haven’t put any LR rock in about 4 months. All my levels are normal unless there's something I’m not testing for and I should be. Ammonia 0, nitrite 0, nitrate <0.5, alkalinity 3, PH 8.3, Phosphate <0.25, Calcium 430, slanity 1.025. Am I missing anything?

I know it's a silly question but you use RO/DI water right? I'm only asking because I did a dumb notlong ago that nearly wiped my tank out by useing RO/DI water from a unit that didn't take out chloromines.

I am using RO/DI BUT i've never checked Chloromines!!! I assumed it did, but all my water ages for about 24hrs before it goes in my tank. I have a 15gal foodsafe drum that i fill before i go to bed turn it off when i wake up then it dosen't get mixed or go into my ATO till that night when i get off work. I hope that helps but i have the feeling i'm wrong. is there a test i can buy or do i need to have it tested?
