2 part dosing help

[bkelly]

Thanks guys, i got my chems from Oceanic in bulk and am dosing manually about 10 ml of each /day based on the recommedations of my tank size and stocking so far my Ca was good after one week but the KH was low (dropped from 8-6) so that be due to the lower conc in solution because of not enough mixing , i guess it would be wrong to shake it up before dosing and immediately add to the tank- ill try more aggressive mixing to get it to fully dissolve. did i read the 2 part notes correctly that you want to add both parts in equal volume , as long as they are fully dissolved, dont try to add more of the KH vs Ca.

You don't have to add equal amount of part 1 and part 2 every time. If you want to raise one parameter, you can add more of that part, spreading over a couple days if it's a big increment.
You can use the following calculator to calculate the amount you need to raise the level of a particular parameter.

How much Sodium Bicarbonate do you guys mix in a 1 gallon jug - ive got the Randy Holmes 2 part paper saying 2 1/4 cups in 1 gallon for recipe #1 and then a direction sheet from Ocean Aquatics saying 1 1/8 cups per gallon. I did as Randy said but can not get it to dissolve so i wonder if im over saturated. What amounts do you guys add for Alkalinity?

think i figured it out, the recipe # 1 is for sodium ash and you add 2 cups the recipe #2 is for NaCO3 and you add 1 1/8 cups,, i must have over added because i got sodium bicarbonate but mixed as for sodium ash. thats why it didnt fully dissolve.
