Calculating Net Volume
I need to figure out my net volume for dosing of medications. I had this nailed down but changes to the system/coral growth have changed those numbers.
Thinking its between 70-75gallons but want to be sure. What is the easiest way to figure out the net volume my system without irritating the inhabitants? Thanks, |

This should help. Do you dose two part by chance? There is a way to calculate volume by amount dosed.

Thanks but I have no idea of the weight of my rocks or sand. I do dose 2 part. I suppose I could use the calculator and see how much a given dose raises the alk.

That's what I did, in the end. Just try some doses and back-calculate to the volume. I'd be cautious about assuming any high degree of precision, though.

When calculating volume based on amount dosed, I would recommend doing the calculations based on the dose of Magnesium. I use 3.5 dKh of alkalinity /day and the amount of time between dose and measurement needs to be taken into consideration, plus I have no idea how long an even distribution of the dose throughout the tank may take.
I have a 180 DT and 30 sump (gallons) and calculating based on dose gave me a net volume of 127 gallons.
