Alkalinity fluctuations

[fishybizzness]

So I started dosing kalkwasser late last week. I've been testing my alkalinity and calcium every day since. My calcium has been around 395-400. My alkalinity has been between 8.2 and 8.7, depending on the time of day. Is this normal for the alk to fluctuate that much and is that something I should be concerned about? Thanks

That’s probably not especially unusual for an ato based system. A dosing pump might allow better daily and time of day control.

yes. That is pretty typical . Doser will keep your tank stable . Best purchase I made for my tank was GHL doser .

Thanks for the response. I'm hoping that it will be stable enough to start getting good growth on the coral I have and to get the coraline to take off again. It's been at a standstill for a while now. I have softies and some lps and will be maybe adding a few easy sps soon. I'm currently mixing the kalk at 2 tsp for every 5 gallons of rodi.
