Calc is 440. Mg is running at 14 to 1420 alk is 10.6.... so hoping the new di and s good vacum and switching to leds will help. Found out the white lighting in my fixtures where wrong spectrum and to low kelvin. My fault gor not chking them...lol
Perhaps someone here with more experience can confirm (my tank shows I'm no expert on algae control, lol), but I wonder if the frequent vacuuming is releasing nasty stuff and just fueling the algae?
