[ctsps]

Hi I have an established 210g main display with mostly sps ,1st question is im adding a deep blue 60gal frag tank and wanted to but a 20g deep sandbed fuge between frag tank and main, will the new sand cause any harm to display(possible cycle) thx

2 is there any way to guard agaist a doser overdosing (bubblemagnus) just wonder if any controller will work thx

It shouldn't create another cycle. The main concern is the sand that would be kicked up from adding the new sand. As for preventing over dosing you can only allowing the doser to be on for a certain period of time by using a digital timer or controller.
