Unfortunately the good old days seem long gone. Local reef clubs were jumping, the forums were moving. Now it’s LED, magic elixirs and frags of frags. I don’t have Facebook but guess that’s where everyone went, RC is a grave yard. I just started getting back full tilt into the hobby again and my thoughts and opinions will not be positive.
I used to pick up 50lb bags of Peladow from water works supply house and pass it around. Remember trying to buy magnesium chloride in bulk. They sold it by the pallet, but I had to buy a truck load, forget how many pallets it was. That didn’t work out to good.
BRS did do good for themselves, started out as two part solution .com selling the ingredients for Randy’s recipe and turned into what they are now. Glad I never drank the kool-aid. It’s still Mrs. Wages pickling lime, inexpensive soda ash and I have a bunch of calcium chloride from the pool store. Don’t use much calcium chloride any more though, but when I do need some I know where to get it.
