I also ran into some issues with my dendros after switching to af reef salt . Got a white film over some of the heads ended up saving a couple lost over 25 heads . Ended up switching back to h2ocean and tank is stable again . Just going to stick with what I normally use unless a switch is %100 necessary in the future .

I've had good results with it. Are you guys that are getting the white film using the probiotic salt?

Using AF Reef Salt and got purple / brown slimy stuff which likes to smother corals. Hit my sps the worst then Lps and Zoas. I have it somewhat under control but it gets worse when I do my water changes. I will be switching back to either RC or something else which is carried locally. For me I saw no added benefit using the AF Reef Salt although some people swear by it.

That strange that it happens. I bought another pail yesterday so I hope its still good.

Been using AF Sea Salt for 8 months and I am seeing cyano problem progressing as I do more frequent and larger water changes. Going to switch to a different brand once this bucket is done.

Starting to wonder, if using the salt but not using the rest of their method (carbon dosing, etc), is that the real issue. That the salt is front-loaded so to speak with traces that would be otherwise consumed if doing advanced UNLS methodology. That those whom aren't, are instead having the cyano / dino problems.

It could be, not sure but it hasn't worked out well for me. As of now I don't see any benefit of continuing the use of AF salt.

I had read about probiotic salt causing cyano problems, but not the reef salt.
For those having problems I wonder if you are using any carbon dosing, bio pellets?

i tried to use aquaforest's carbon dosing method (probio S and NP pro) and found they were just too effective. they basically drove my nutrients down to unmeasurable which obviously is far from ideal. not to mention it seems counterproductive to be carbon dosing and immediately after dosing NO3 and PO4 just to keep your corals from starving.

What I found is my corals love af reef salt. I had some of the outbreaks too, but the af seems to be lower on ph than others so I just keep my ph/dkh in check and it all went away. been using for 4 months now or so.
