    My levels sit at KH8.1 CA500 MG1480 in my tank, they will take about a month to drop to KH7 CA480 MG1280, then I do Atwater change and I'm back to square 1.
    Obviously as I'm running Zeo, the latter numbers are better but my biggest concern is the swings I'm getting by doing a water change.
    I think a salt with minimal elements would be better so that I could ball my levels to keep them more stable, do you see this causing me problems and do you think it's ok to carry on like this until my corals start using more and I can start balling

    The more answers I get just lead to more questions!!

    Karl, welcome aboard! Opinions are free, therefore we get alot of 'em. Although I work for Vertex, I've kept marine aquariums since the '60s and have racked up some experience and opinions. And, you never get to the top of this learning curve. Something I love about this hobby/business.

    Gazz,

    that's a hard one to call. Every tank is different and it sound like yours is still maturing. If you want to boost the calcium extraction, add a couple of fast growers, such as Montipora foliosa and M. digitata. Have you used the Zeovit salt? I used it for a while and it is NSW leveled.

    You're right, swings are to be avoided, but I'm surprised they are so strong for you. I change 5% per week and didn't have a real problem with swings in alk with boosted salts. Maybe less water change, done more often is a temporary solution.

    Please understand, as I work for Vertex, it would be unseemly for me to do any critique or recommendations on the various salts available. You will find more information on manufactures websites, often real analysis. I have noted many stores only carry one particular mix from a manufacture, while others may be available.

    Hi all

    Just trying to learn a bit about ULNS/ZEO.

    Do you get problems running high KH and ULNS because of having no NO3 and PO4 or because of the additives used to achieve this?

    Your corals will suffer with KH burns, thats why you aim for levels as NSW. Kh should be around 7.5, Ca 420 & Mg 1280

    Since upping my KH from 7.5 to 9 and holding it stable, my one and only SPS and m.digitata has started receding at the base.

    I don't dose any ZEO or anything but I do have zero nitrate and PO4 just from natural filtration and Rowa etc

    I wondered if this could be classed as a natural ULNS and my KH9 is hurting things

    Quite possibly, I believe that is called RTN. Cannot be called natural if you are using Rowa!
