The vinegar makes it so you can dissolve 3 tsp kalk per gallon rather than just 2 tsp. It's also a carbon source to lower N and P.

The 3 tsp goes into 1 gallon of RO/DI and that mixture is dosed at a rate of 800 mL per day so the 3 tsp goes into the tank in a little under 5 days. I have room to dose more - it's not affecting pH much at this rate.

So you dose vinegar in addition to Prodibio. Are they not a similar purpose?

Thats a beautiful batch of frags.

IME, Prodibio has not affected N and P in any tank I've ever used it in even though that's what it's advertised for. I notice SPS color improvement when I use Prodibio BiOptim and BioDigest in tanks with SPS even though I don't see any difference in nutrients or other measurable parameters. I don't notice this difference in softies or LPS. I do think that it helps keep the good bacteria population up so there is less opportunity for bad bacteria in the tank, but that's just speculation.

The vinegar is a carbon source, but the main purpose I use it for is to increase the saturation of kalkwasser.

Yes, the frags are nice! Thanks to Coral Master Greg!

Good info Mindy. Thanks. I use a Tunze kalk mixed, so assume vinegar can't just go in the make up water ?
