Can I add epsom salt to my tank randomly? I know it's fine for the bettas but I have some live plants and snails. Is epsom generally a good for plants? Most of the websites I found mentioned using epsom in place of fertilizers. I am using Seachem Flourish. I just don't want Milly's and Brutus' shells to get soft.. And any potential pond snail babies.
try using this calculator :) http://calc.petalphile.com/ my guess is that you will need to add more magnesium because there are only trace amounts in comprehensive.
In the dropdown I would pick estimative index/low light
k2so4 (instead of the kno3 in EI dosing because i dont need the nitrogen)
I just use the calculator to mix the required amount of dry ferts with water and dose from there, I have months worth of mixture done up lol, just add it in during water changes (except for iron that gets added on a different day)
