Yep here we go , my125 with 30 gallon sump has 120 gallons of water total. Alkalinity has been up and down adding .5 teaspoons of reef builder to each gallon of top off water . Will test this weekend should be close. Other than that reef plus 2 times a week . Coral look a lot better with the reef plus. Makes skimmer works alot harder I know that . Mostly zoas got a pulsating exenia, looks real healthy. Did put two montiporas in encrusting ones doing ok . One is turning white alittle on the edges
so I turned my light down a bit. Seems to have worked so far. Time will tell .
