We have a 15,000 gallon pond which we have enjoyed for 5 years. I find that if I keep the salinity in the pond to about 1% the fish are happy and it does not bother the plants. I have purchased aquarium salt in 50 pound quanities in the past. DH and I were discussing other options for salt. Does anyone know if other forms of salt can be used? We are thinking water softner salt that comes in a block, pool salt or table salt or other options...
Appreciate the input.
I use normal water softner salt (from Lowes or WalMart, etc) Make sure the one you buy is ONLY salt, they carry several different varieties (some to keep you water softener clean, etc)
Our Lowes carries the Morton Salt brand (just like salt shakers) but in 40 lb bags for around $6. It's an aqua colored bag.
