Zeovit system vs. Algae scrubber

[SantaMonica]

Well that pic does show what was left out of the Smithsonian study. And 1990's sounds right... about when they they discovered the calcium and alk had dropped to bottom levels due to not dosing, because they did not know they should. I guess that would indeed kill the corals. Probably why the TOTM SPS guys have "rock solid" cal and alk dosing as stated.

The studies look like good reading; will add to the list. Wish I had the time I had before (used to read one or even two studies per day).

The sign was posted during the crash of 2013. Not the crash, or crashes, that took place in the 1990's.

The importance of calcium and alkalinity were understood in the 1990's. In fact, it was understood in the late 80's. Authors like Martin Moe wrote about it in their books, it was written about in FAMA and other magazines, and product manufacturers were supplying it. (especially in the form of kalk, which was very popular.) If Dr. Adey and the Smithsonian didn't understand the importance of calcium and alkalinity in the 1990's, it's just another example of how poor their understanding has always been.

I'll comment on this thread as someone who actually uses Zeovit as I'm seeing a lot of misconceptions about it on here.
I've been using it for 6 months now and am achieving results I've never had before with SPS. All my corals seem to be doing really well from Acropora to chalice and Goniopora, huge polyp extension and really nice colours.
With regards to the 'pastel' colours, I don't have that, however I have seen many tanks that do. Zeovit is a constant balancing act, not a hard one but a constant one. I feed more heavily which zeovit allows me to do, this increases fish health and allows nutrients for my corals, I aim for about 0.02-0.03 phosphates.
Using Zeovit is not labour intensive, I spend about 30 seconds a day dosing, I have no biopellets to change out, no UV, no Ozone, just a Zeovit reactor which I change the stones in once a month and a carbon reactor.
All in all I find it a very easy system and with regards to Zeovit crashes, you would have to make a monumental dosing error to achieve that. I massively overdosed Zeostart3 during my first month and got cloudy water for another month as a result, fish were fine, coral was fine.
