How big is your tank, really?

I was curious about actual water volume before I start doing any kind of dosing.

I have a standard 90, but with sump and fuge I figured I was at about 100g of actual water volume. I knew there would be some displacement from rock and sand, some extra volume in plumbing, etc. I was surprised when a system volume calculator put me right back at 90.1 gallons.

I used this calculator:

Anyone use this one, or have another one I can try to compare?

You know you're cool when they don't have your tank shape!

I'm cool.

Cool calculator too.

You know you're a dork when you go back and see your tank shape after already posting you are "cool".

I'm a dork.

I would start dosing as if it was a 70g then test and up the dosage from there. Just my 2 cents.

Dang it, you should have posted that like 2 minutes ago...

Don't worry without ever useing 2 part before, It will take awhile to get all the levels up were you want them I would think.

I will have a massive sandbed in my next tank and already used a calculator like that to figure out that my water volume will only be around 170g in a 215g with a 55g sump.
I am dosing the bulkreef stuff so it's easy to keep track of it and calculate/adjust.
