Ya.. all that thread did was confuse me! First it talked about reef salts vs diy salts then talks about baking soda then other chemicals, hehe. I guess I'm just not smart like that. I didn't know people made their own salts. Anway..
I use baking soda (from the supermarket) and do not have any nuisance algae issues. Maybe because my baking soda doesn't look like poo ? Parameters are at the correct levels and everything is thriving
Also buy my calcium and mag bulk from the chem dude. Gets the job done and works great.
