I think this problem started about a month ago when I switched my lighting system from all t5 to half t5 half led.I understand corals take time to adjust but some days consuming elements and others not just seems strange. |

![]() ::::UPDATE:::::
this morning I added 10 tsp of calcium chloride anhydrous to bump up my calcium (thinking maybe the calcium kit being older was giving me a bad reading). That should have brought my calcium to 435ppm. Actual results tonight Alk 9 (up 1 dkh without adding any) Cal 470 way higher than I dosed Mag 1430 (up 110ppm and i didn't dose any) ![]() |

![]() While ca is not bad to bump up quickly, I think long term you gotta figure out what your tank consumes weekly then adjust accordingly. I admit when I was setting up my doser Param's bounced quite abit as ca was low and same as mg,
But once my alk stabilized I've been testing weekly and it's rock solid for months. I had lots of po4 built up in my tank which slowed the growth of sps and coraline, this played a big impact on how much of the big 3 gets consumed especially alk. Our tanks is a constant adjustment, this is what makes it fun. If there was nothing to tinker with one could get bored.... If you're testing a lot you must be going through test kits. Like Gary said if you can afford to or see one come up Fs in your area get the Hanna for phosporous and alk, I find them to be a lot more accurate. Do you use a measuring cup or digital scale to measure the bulk Chems?

I make all the different chems using a a digital scale. I'm looking into a calcium reactor, that might make this a lit easier to balance out. Probably doesn't help that my doser is a Jebao that gets jammed up every couple months. Thanks everyone for all the help ![]() |

![]() You should use Sodium bicarbonate for alk

Sodium bicarbonate is awesome to use as alittle amount can bump your alk up, only downside is ph rises quickly too!

![]() I doubt it's a test kit issue if your using quality kits. Titration method testing is more accurate for Ca, Alk and Mag then the digital colorimeter tests. Info direct from Lamotte technical support.
My suspicion is it could be related to carbon dioxide levels in the house and consequently in the tank. How does your pH fluctuate during a day? Monitor it over a week long period, say every 3 or 4 hours. There may be a correlation between co2 levels in the tank(lower pH) and the alk issue. ie High co2 would cause the alk to be depleted in the tank. Cheers, Tim

I prefer to use sodium carbonate (soda ash) as I suffer from low PH. |
