Estimative Index
Use this program to determine a bespoke EI dose for your planted tanks.

- No mathematics.
- No calculations.

This calculator is based on data taken from: -
“The Estimative Index (EI) Dosing with Dry Salts” by ceg4048 – UKAPS.org
Great help & you just know it will work if ceg has been involved.
TYVM you’ve solved all my problems
Brilliant guide, thanks a lot guys
Anyone else finding that they can’t see all of the stock solution dosing regime? It just cuts off below ‘day one’ and I really want to use it!
Thanks for posting this though, it’s a great resource
