Salt: Reef Crystals vs H2Ocean

[daniella3d]

solution, change less of the water but more often.. I now change 15% every 2 weeks instead of changing 30% once a month. just 15% does not change the alkalinity too much and I stop dosing for a day since I don't need to for a day or 2, then I resume my dosing pumps.

The more I got in alkalinity raise was 8.5 and I keep mine at 7.5
