the place where i got water from sux i realized about a 2 weeks ago, so its been 2 weeks w/o a water change, my ca was that 2 days ago so i dosed with BIonic yesterday and today, i just changed my water today and got it from aquatica, a local LFS. So should i dose with BIonic like crazy till I get up to at least 350??? My power heads are blowing directly at the sps but from across the tank. About a foot and a half away.
