I did not read every word of it, but they do pack a lot of correct science into it, including a correct debunking of the Fauna Marin claims of hydroxide dosing causing problems. Most of what I read is well written and explained.
They still seem to use confusing comments about dKH in a liter of supplement, and they give what I consider are unsubstantiated assertions about certain trace elements with no known biological requirement such as rubidium and barium.
Hi Randy,
As a long-time user of Reef Zlements and also a massive fan of yours, Randy, as I truly believe you have contributed significantly to the hobby over the years, I actually reached out to them regarding the points you raised given that, every time I spoke to them, they seemed to know what they are talking about.
They acknowledged that the way they present the alkalinity in their products could be better. For example, they mentioned that the correct way would be to say that the alkalinity in their Part 1 is around 3570 meq/L, but rightly or wrongly, they’ve always written it the way they have to allow reefers to more easily compare their solution with others on the market.
They didn’t mention other brands but, I had a look around and found for example ATI Essentials Plus is described as “Highly concentrated (28.000 °dKH and 200.000 mg calcium per set), ready to use” or Oceamo (which I understand you have great respect for Christoph who is very active in R2R) also state: “1 liter DUO contains 10 000 dKH units”.
So, I suspect the reason is as they say just to allow people to directly compare their product to their competitors.
I also brought the traces up in the conversation and they assured me that every assertion they make about these elements is backed by peer-reviewed, published research. They referenced these studies at the bottom of the manual, so while some elements may not seem essential at first glance, they’re relying on credible sources to support their claims. I found that pretty reassuring in all honesty.
For sure having read the H2P comprehensive manual now for 3 times, I cannot find anything like it from a vendor so far, as it is extremely comprehensive, going from the pre-requirements to set up a proper tank to water changes, dosing, nutrients, etc. I personally think we are lucky to have a brand like them in the UK!
