Need help with diy 2 part. Also has anyone had success with this?

[Major nc]

Brightwell 2 part has been hurting the wallet lately. 2 litres of each part a month. $55 plus a long drive and spending another 50-100 just cause im in the store loll.Ive been supplementing with kalk as well but would rather just use only 2 part. No room for calcium reactor.

Heres a thread for a canadian recipe im going to try out next month. Around $50-60 should last a year. http://www.reefcentral.com/forums/sh....php?t=2476803

Has anyone tried this? If your making your own, please share your ingredients and procedure here please.
