Having a hard time with salt. Finally sdet up a copper system for fish.
let me know if you have any other troubles with um. I had a death rate of less than 2% in my systems. Copper is one way to help keep the rate down.
I still have some contacts in the trade to if your wondering about suppliers for things you can’t find.
Do you sell coral? probably already know but keep the coral and inverts out of the copper systems.
