Recipe #1, Part 2 dosing rate

[dbrown]

I'm going to be dosing this into 70 gallon volume was wondering what rate in mL/hr is safe. If someone can explain how to calculate that I would really appreciate it.

If you are talking about my DIY two part, you can add each part all at once to a high flow area, preferably in a sump or otherwise away from organisms. Add the other part a few minutes later.

I use a dosing unit.I think its great but it depends on your tanks needs.Since my tank requires multiple daily doses I found a dosing unit to work well.Plus you set and forget it.

I am not using the part one since my calcium levels are fine, I am mainly concerned with pH spikes whiile trying to raise KH. So basically as long as I dose into a high flow area am safe with any amount?

 

[steve the plumb]

yes you will get a spike but it goes down baking soda doesn't maintain ph like kalk dose.

Thanks steve. I'm dosing like 50ml in hr into the overflow so it goes down into the sump and into the skimmer. Kh was down to 5!

I use randys formula bake the soda at 350 for 1 hr.bake about 2 small boxes in a pan.I think you put about 21/4 in 1 gal of R/O water.I have the formula written down but you can get the correct amount from this forum.I use a dosing unit ,dose every 6 hr for 30 seconds.I use the aquamedic reef doser.I didn't need to dose the calcium as much or I thought so but now I have noticed corals are starting to grow and demand has gotten stronger and getting the twin doser was a good move.If you keep adding acros the demand goes up.5 DKH little to low.Try to keep it at 9.

The pH effect on adding 0.5 meq/L (1.4 dKH) using Recipe #1 is probably about 0.3 - 0.4 pH units immediately (although it may be less if the baking was not complete).
