What is the right amount of baking soda to bake and to put in 1 gallon jug? I seen people on YouTube use 1lb(one box) then I seen the "œrecepi #1" Then there's recepi #2. I just wanna make 1 gallon jug and dose manually. Also it says on the calculator from dr Farley-Holmes recepi#1 calculator that's I would need 217 ml of it to reach my desired level. Can I do this over 2 weeks? Like 217 ml divided by 14 days? Also I'm planning to use Seachem reef advantage calcium, is that ok to use something else for two part and not use dr Farley Holmes calcium part. Thanks
