yeah I noticed that on randys recipe #2 and was wondering if I was attempting to supersaturate the solution or something. I think I'll either heat or try a powerhead and see how it goes

Oh you're doing the unbaked, right, sorry. Yeah, I dunno. I found that the half recipe mixes in eventually but it just takes forever. Better off just putting a powerhead in the reservoir and let it mix forever and ever and it'll eventually dissolve in.

It's the baked baking soda that reacts too much when added too much at a time and once it's done that, it's done forever.

I still don't really know if one method works better for me or not.

I noticed when adding the baked solution to my sump it would percipitate into clumps.....so I mixed it with some RO water first before adding it and now have no problems.

My recipe i have used for about 10 years

STOCK :

1 BOX baking soda
1 box washing soda or (1 box baking soda baked at broil 20 mins)
vinegar to adjust pH of buffer

Stock Concentrated dry

6 part baking soda
1 part washing soda

mix very very.

to test:

1 tsp will raise the ALKALINITY Ka by 1 unit (on the D) in 25 gallons of water.
and should maintain the PH at 8.2

test a small sample
1ml into a fresh water gallon.
test pH and check that its 8.2 (the buffering capacity of the two)
test Ka: before and after it should be pretty high. due to this sample being very concentrated.

check a 5 gallon bucket by adding 1ml of the dry powder
it should read 8.2 ph and the ka should raise by 1 unit.


keep as dry stock and make a pop bottle up with a tsp. or so.
do not increase Ka by more than 1 unit a day

Hi Christy

I am using the Bulk Reef Supply

Bulk 2 Part Instructions: Recipe 2

It calls for 1 1/8 cups of BS to each gallon of RO water.

I mix 5 gallons at a time in a large 6 gallon salt bucket with 6 cups of BS.

I use a MJ 1200 pump and let it mix for a couple of days with little to no residual.

If you feel this recipe ids too week you can just adjust the dose either frequency or quantity.

I would not want to dose if there is any residual in the water.

I mix 1600gm in 10 liters of water. Not sure what that is in cups, but I like to be accurate. It makes it easier to set your dosing amount. I just shake the container a few times over a couple of hours and it mixes clear.

1 cup = 250 ml

A box of Arm & hammer is 500 ml or 2 cups
