Dying Torch Coral...!

[niloc16]

salinity is low for corals. 1.021 is ok for fish only but i would slowly bring it up to at least 1.023

I was thinking osmotic shock,but with that low salinity maybe not.Alot of LFS have low salinity,so maybe not such a shock.How long/how did you acclimate them?Im wondering about possible PH or Alk shock.

Isn't your lighting kinda low too? I don't know anything about T5's but 56W doesn't seem like much. (The blues don't count).

Didn't you just start this tank like a week ago?......If so I think it's still a liitle too soon to be adding corals probably some nasties coming out of the sand or the rocks from the move. The flesh isn't gone on it yet maybe someone with a more established system can nurse it back until your tank is ready. From the pic it looks to be low in the tank did you try higher? and I don't think those lights will cut it, it may substain life but it probably won't grow much.

My torch is doing just fine, actually doing well under a 28w T5 10,000k and actinic so I think you're fine for light. Make sure you have adequate water flow they like water to flow around them but not directly at them and yes if it's a new tank there could be dozens of reasons for it's withdrawl.
If you live close to a fish store take a water sample in, have them verify the tests you've done, depending on the test kits you are using there may be a problem there. I've used the budget/inexpensive kits in the past and seen huge differences in readings from one kit to another, now I'm sold on Salifert and frankly, I'd rather spend my money on them, I feel confident in the quality and if my pH reads 8.3 I'm comfortable with it actually being 8.3

I keep my tank at 1.025. When I buy or trade something new for my tank I always test the water it comes in for salinity and then acclimate accordingly.

I looked back over some of your old posts, you just set up your tank 10 days ago.. I realize you bought a used system, but it still has to stabilize after the move.. and depending on how you moved it.. rock, sand bed, etc this could take a while.

Help... Skimmer question
Hello, we just picked up a used saltwater system and finally got it all running a few minutes ago

[fishbait]

Yes, we did just pick up the system recently. The tank has remained stable since the move - no spikes in any of the levels that we have been watching (all the ones above). That said, we may have jumped the gun a bit in introducing corals - the LFS didn't seem to think it was a big problem though, so we took the plunge.

As I am typing I am preparing some extra salty water - I will introduce a few gallons tonight and some more tomorrow to try to raise the salinity a notch or two. I am also going to move the torch up higher, get him closer to the lights.

I didn't realize the blue T5's don't really count towards total wattage..? Can someone expand on the reasoning for that a bit further?

We've been using the cheap Hagen kits for Nitrates and Ammonia (came with the tank). The same kit for pH (a new one) didn't even give us a valid reading - it was way off the charts. Instead I borrowed a digital pH meter from my Dad and that's what gave us the 7.9 figure.

[fishbait]

Ok, I've added in the salt (I had some saltwater already made, so an additional half a cup dissolved quite fast) - I think it brought up the whole system about .007 - I'm getting close to 1.022 now. I will do the same tomorrow, then maybe wait a day and do it once more... how long is a good amount of time for these sorts of changes?

[Borderjumper]

What are you using to check your salinity? Swingarms can be totally off. I had 2 and each one gave me a way different reading. Get a refractometer.. one of the best investments you can make!

Be careful putting in "new" saltwater. It really should sit overnight before you use it.
