Reef math: What do you use math for in your reef keeping?

All this talk about cubed reef this week has got me thinking about math! Don’t worry, we won’t ask you to solve any differential equations or do any non-Euclidian geometry, but I am wondering how much math you use as a reef keeper? Do you just wing it or follow what others suggest? Do you do the math yourself or maybe use an online calculator? Whether it is figuring out the dimensions and weight of your aquarium, doing salinity conversions, or dosing measurements, let us know what you use math for in your reef keeping. Bonus points for an explanation of the calculation of specific gravity using milk in your answer!

I use ADDITION to add up all the costs.

My wife uses SUBTRACTION on my monthly budget spending when she reviews the credit-card statement

LOL I use all the math for everything, from figuring out how much sodium nitrate I need to add to fight dinos to how many LEDs I need to get 400 PAR to how high the water will rise over a weir.

Unfortunately, it doesn't help much :)

There is a TON of napkin math in reefing. It's fun imo doing all the calculations for pumping and flow and such and seeing the fruits of of that math labor lol

 

[Miami Reef]

I use conversion math a lot!

Reef math is like chicken math.

Right?
Also, I have three (3) chickens. I need more of both.

I use subtraction from my banking account of all the reefing costs. Then at the end of the year I use Bank calculator, which tells me how much I spent on my hobby and then I book a visit at my therapist to improve my mood.

Calculations.

How much cash can I get from a refi to remodel the reef?

1 + 1 = 2 dollars I have left for food this week after my BRS order.

Having large tanks, you can only imagine, I watch weight of tank and contents and for dosing

I don't think measuring cups classify as math. :beaming-face-with-smiling-eyes: If I can't count them in my head paper isn't gonna help.

Oh. . . the other is my budget:

 

[Crustaceon]

If I had one of my four RBTAs split last week...and that splitling just split last night, how many RBTAs will have in six months at this rate?

 

[Sean Clark]

Counting to 5 is a lot harder than one would think...
Wait, was that 3 or was that 4? :thinking-face:

 

[Reefer911]

The only math I need is the + sign to add the $$$$$ spent

 

[ScubaFish802]

I'd be interested to see pics of the tanks that said 'No math here'. You're telling me you aint even measuring salt out? :thinking-face:

I ain't no math magician that's for true
