Volume vs Weight

[frogabog]

I'm struggling with pool math app because all the amounts are by weight. I don't have a way to determine weight, but I can do volume. I overshot it a little yesterday. Not by much, but enough to now want to lower ph and alkalinity a bit to get back to ideal. How do y'all manage it?

If you use the Old Web Poolmath, it gives you both by weight and volume!

To be honest. Most items it is wash. At least for CYA. I don't add any other solids (except salt, no need to be precise with that).

I use a four cup plastic measuring cup from Walmart...it has ounces...

I use what Tom uses and it has served me well! I get the results I expect.

I have a little 4 lb digital scale for weighing out dry chemicals, and I use Ziploc bags to put the chemicals in (store brand ones). Easy to carry out to the pool! I think the scale was about $10 or so on Amazon.
