Hi everyone, Happy 4th of July

Did some partial w/change with the Crystal Sea salt the other day(second 5g change in a 75g tank) and one of my Acroporas(cerealis) has bleached.Still have nice blue tips but four or so days ago it was nice yellow with blue tips
I hope it regains its zoox(if it's been expelled?).
Here's a pics from before and after the water change,tell me what you think,guys

Well we are getting a pallet of the Bio-assey next week if the shipping company decides to deliver it since it has been in town since tuesday.
I plan on doing only 1 gall water changes every 2-3 days for a month for a slow acclimation to the new salt on my 90gall.
Granted my tank is lps and softies with a single sps cap though.

Gregg,

I'm not even sure that this event relates to the water change or not

I also changed a bag of carbon in the sump as well so maybe the water got a bit clearer? Nothing else seems to be affected. This is my second water change in like three weeks,after first 5g I changed about 2 gal a week and then did the 5g again. I think the coral will comeback to normal after couple of weeks,atleast I hope so

It probably will come back if it jsut bleached some.
The carbon could also have a big effect if you have not changed it in a month or so or have not run carbon for while. Good point.

with all the reports of bleaching events after people switch to crystal seas salt -id say at this point there is definitely a corralation..there is no way in hell id use that stuff..in dr rons salt study-he used the analysis provided by crystal sea..the only test he actually did was with the urchin larvea.besides that-i dont trust the parent company-which has had a bad reputation in the past.

nope ,no way, not me...if i were you id go back to what works..and leave the crystal sea salt mix to the people who want to raise urchin larvea..jmo

Like I said before,I'm not sure if it is related. Change of fresh carbon and I also did totally cleaned up my sump of the gunk(was sorry to see all the mysid shrimp get sucked up,but hey... ). FWIW, my 110g tank is now about 99% CS and nothing had bleached there or reacted negatively-it took me about month and a half to do it. In the 75g only this one colony that reacted this way,nothing else had skipped a bit.
I for one don't want to speculate on Ron's study or say that larvae survival is of no importance,it is to me. The salt composition seems to contain less heavy metals and Ron was trying to show that they are toxic.I think he'd done that,atleast in MO.
There was also reports on a higher survival of seahorses in juvenile stages(almost 99%) from the breaders that switched-important as well. The event that I reported is of a single colony and does not implies that I will or would bash Rons study,ever...Perhaps it is the change in itself that caused that colony to bleach and not the salts composition or defficiensy in something that other salt had.I'm hoping that it will comeback to its normal coloration soon and that I will have higher number of the tiny life in my sand bed and my LR, I really believe this or I wouldn't have switched to this salt mix.

im not bashing rons study at all-im bashing what he DIDNT study or have analyzed-and thats is the composition of the salt-like i said-he took the manufacturers word for it on how much heavy metals it contains...you gotta read the fine print

im 100% sure that rons study was a noble effort-just not 100% sure on the results or the composition of the salt...i myself switched from io to nsw after the study came out ,but there are just way too many reports of bleaching after switching to the crystal sea salt for it to be coincidence imo -and i wouldnt trust the stuff based on the results my fellow hobbiests have had.

OK!


I didn't mean to say that you were bashing Ron, I said that I won't
or the salt for that matter. Just too many variables to consider to say that salt did it. Plus,it is just one colony and I don't see how none other coral that reacted negative.
I will see in a little while how this colony does and post results,good or bad.
