    2nd week of tests in after installing Ca reactor,

    Ok , my first week of tests were :

    Temp : 82 Salinity. 1.0245 pH 8.1 alk 2.51 Ca 490

    This week the tests were ( day after a 10 gal water change )

    Temp : Salinity. 1.0255. pH 8.2-8.3 alk 3.71 Ca 510

    So obviously i've had alot of change in my parameters over the last week, my calcium actually went up!! I tested it twice and got the same result, and as did my Alk which was also tested twice,

    Any input i could get would be appreciated!

    Thanks

    your ratio between calcium and alkalinity is off. An alk of 3.7 is good but 510 for calcium is too high. i'd say shut off the reactor until your calcium falls to 420 and continue testing alkalinity during this period. As the alkalinity falls. add small amounts of buffer to keep it stable as the calcium level falls. Once you have an alkalinity of around your existing level and a calcium more in the normal range turn the reactor back on and slow it down a little. it is obviously over doing it's job at the moment. There is no guestion that the reactor is working!!

    I'm using salifert tests, and i must say i'm pretty impressed, i just got them but whenever i re test i get the exact same as the previous test, very precise, and very accurate.

    Reefmutt, should i test the effluent ?

    you could if you want, just to know where you are at, but it uses up a lot of reagent to do so and you know that the reactor is producing calcium and alkalinity. testing the effluent only tells you whether it is working or not, testing the tank tells you what it is doing to the tank- which is more important.

    Ok, true enough, maybe i should just turn the c02 off instead of turning the whole reactor off, or just turn the bubble count down to 1 per min or so

    Keep in mind that no matter what you do to the reactor, the ratio between calcium and alkalinity will stay the same. Since the reactor is adding a balanced additive of both calcium and alkalinity, they will raise or lower together. What you want to do is change the ratio so that your calcium isn't as high as it is now in relation to the alkalinity. If you turn it down and the levels start to drop, give the tank a shot of buffer and than get the reactor stabalized with the new corrected ratio. I'd say an alkalinity of around 3-4 with a calcium around 420ppm would be what to shoot for...

    I have a ton of alk buffer here, i stocked up on it then bought a ca reactor for some stupid reason, i have acouple jugs of Ca additive as well, so if i can just get my calcium down then boost my alk i should be good, maybe i'll do another water change tomarrow, the hair algae is driving me nuts so doing another water change will serve two purposes
