Soda ASH IFC calculator help ?

[eminor]

Hi, it's hard to find a sodium carbonate calculator when you don't know much about chemistry, so i tried with the wonderful IFC calculator, i have an auto doser that will deliver 10ml/day ~ 0.015 dKH per day, that tank is young and consumption is slow right now


If i did thing right (pictures)

I need to add 4.45g of sodium carbonate in my 400ml container, and 10ml of that solution in the 80 liters aquarium deliver 0.015 dKH, is that right ? thx

You seem to have set your dKH target to 0.1, not 0.015.

Yeah, the weekly target is 0.1, divided by 7

edit: i'm kind of confused, my weekly target is 0.1 but one dose of 10ml will provide it when i want 10ml to provide ~0.015

As this is dKH, rather than fertiliser, you’re aiming for a set dKH which you try to maintain, rather than build up to with regular dosing. As such, I’d recommend adding the required salts once per week at water change. Remember, that you dose only for the quantity of water that you’re changing. Therefore, if your target is 0.1dkh, then you dose your amount of water change water to be 0.1. That way you’ll maintain your entire tank at 0.1.

Spot on.

The ReminCalculator was not designed as the other 3 calculators. It does not rely on the Dosing Wizard in the TankAndDosing sheet. As you noticed, when you chose to do a Solution rather than Dry Dosing it will use the information you input here:
but as you see there is no dosing frequency which means each dose will fullfil 100% of the target you are aiming for, in your case 0.1dKH. The reason for this is that remineralizing is something you do in one shot, not through the week. If for whatever reason you still decide you want to dose daily then do a weekly target of 0.015dKH so that at the end of the week you will have 0.1dKH. But to be honest I don't think this is a good approach to remineralizing water. In your case it probably will not matter at all considering the minute amounts since you are aiming for. 0.1dKH which is virtually 0 and no commercial test out there will be able to detect those tiny amounts anyway.

SPS won't like that, they need crazy stable parameters, Acropora won't handle it. i've seen SPS die from low swings

Spot on.

Thanks, i see, i made the change, took me time but it's actually easy

Actually the use of sodium carbonate made me suspect this was not for freshwater but considering the amounts I didn't really think too much of it. Since I know nothing about reef tanks I can't comment on the dosing schedule but I am glad you were able to figure it out.
