Two Part Dosing - Vacation

[Gondore]

I am leaving on vacation this Thursday and I have someone setup to care for my tank while I am gone. I have been dosing my tank with 45 ml of two-part (from Bulk Reef Supply) each morning for the last month and it seems to be holding my parameters in check. The individual who is caring for my tank has to drive about 30 min. Because of this I has hoping to only have him come over every other day. My question is should I have him double dose (90 ml) when he comes or just stick with my regular dosing of 42 ml even? Any thoughts would be appreciated.

Double

It's hard to predict what the daily dose should be. As the alkalinity and calcium levels drop, calcification slows down. I'd probably bump it up to 50 ml and be on the safe side, rather than overdose.

I was also thinking 50-60 ml bertoni. I am more worried about overdosing than underdosing. I will only be gone for 4 days.

Sounds like a reasonable bet to me.
