So I've got my 46 Bowfront reef tank locked on now. I have alk daily at 9.8dkh, Ca between 410-430, Mg 1320-1350. Nightly I add exactly one cup RODI water with 6g of Seachem Reef Builder mixed in. I was wondering instead of mixing it everyday if I could take one gallon of RODI water(16 cups) and add 6g x16=96g Reef Builder and mix it up that way to cut down a little on daily maintenance. If I could do it like that then I would have enough alk solution to last 16 days. Just have to shake it up a little and measure my one cup and pour in sump or even better yet slow drip if I can get around to making a diy drip system one of these days. Thanks
