Skimming & calcium
 

Just curious,

Recently ran out of my DIY 2 part (specifically the dow flake), started using kalk again.

With the dow flake based calcium part - I noticed my skimmer went into underdrive for a few hours after dosing...

Now with the kalk - I've got a skimmer cup filled with big bubbles (its a CSS220 - not used to seeing such things), and had to dial it way back after the collection cup overflowed twice.

Is this normal? Will the addition of a kalk reactor make this kind of skimming a bit more consistant?
