It has been just about four months since I started using Captiv8 Aquaculture salt and I wanted to provide my initial thoughts on what I have been seeing with my tanks and also some interesting tidbits about the salt itself.

I had been using Instant Ocean salt for a number of years and for the most part I was happy. My corals looked good and the salt was pretty cheap. I did have to supplement magnesium since freshly made batches of salt tested out at around 1270 ppm for that element. I never tested for calcium and alkalinity so I can’t comment on the consistency of those components.

Another knock I had against Instant Ocean is that it mixed up really dirty. I have been told the residue is not harmful to any tank inhabitants but I did wonder if it impacted the mixing pump I had in my salt water mixing drum. It seized up on occasion despite regular maintenance. The Captiv8 salt mixes up very clean.

A Brown-out Incident

Ok, as for my corals, they had been looking good with Instant Ocean. But there were three browned-out corals in my peninsula tank that started to color back up after using Captiv8 salt. I believe they had browned out due a rise in phosphate but that is just a theory of mine. I should also mention that I started to dose some Captiv8 Aquaculture trace elements around the same time I started to use the salt. At this point I am still dialing in those traces based on some ICP testing I am doing with Reef Labs.
