    The only device comes to my mind that is acting randomly is heater, and I tested it.
    Potassium is tested and replenished. WC would not hurt at least.

    Just wondering what you used to test and replenish k? Also I have read that many shelll fish contain large amounts of k so if you feed some shellfish would you have to dose??

    I've tested mine a few times and it's about nsw values.

    If you are scrubbing, you should be testing. I use a salifert kit and dose 30ml per day of Thrive potassium. This supplement isn't very concentrated which is why I got it, for use on a dosing pump. Kent's product would work just as well. Do not dose potassium iodide to try and raise potassium levels. I shoot for 410-430 ppm to enhance acro color.

    Santamonica, aren't you feeding your scrubber algae back to the animals?

    I also use the Salifert test kit, but most liquid supplements are waaaaaay too expensive (you pay mostly for water in a bottle) I prefer Brightwell Potasion-P which is powdered and you mix to strength, and you can also put this in a doser.

    Also remember that comparing your tank to another tank and what they do is completely irrelevant. You need to test YOUR tank and dose what is required for YOUR tank.

    I am using salifert kit too.
    This K solution isnt concentrated but isnt expensive as well.


    P.S. tested for stray voltage at different times of day to be sure. Interestingly highest voltage was ~3 VAC in the late evening when all lights come off and wortex MP-10 come to night(slow) mode too.

    Update here. And new problem too.

    All algae is gone by the time (good news) , except one (bad news). The one left is "Caulerpa verticillata" and I have no idea how to kill it. Actually it is slowly spreading around. My tang and blenny doesn't look interested in it at all looking for other types of algae instead. Emerald crab is very shy , so is not providing any pleasure to watch him tearing that particular algae too.
    Magnesium stays still high after I raised it trying to kill other algae, but this is not bothering Verticillata at all.

    Are there known methods of dealing with Caulerpa verticillata ?
    Looks like that :
