BRS Aquarium & Reef Calculator question

[Arricefe]

BLUF: The BRS calculator says I should dose 41.6 grams of BRS Dry Calcium Chloride to raise my calcium to the desired levels, am I supposed to mix that amount and pour it in the tank all at once?

I assume that the best way to dose is to dose as the elements are consumed which makes the Trident approach the perfect solution BUT I don’t have the resources to do that. I need to dose manually. So do I mix and pour all it once? Do I space it out by minutes? Hours? Days?

So I’ve decided on a course of action (sort of) as I was reading my own question but I’m still interested in your thoughts. I do plan on getting a pumps and dosing containers in the near future but in the mean time I need to dose manually.

Makes sure you are using the right aquarium volume if you are going for that level of precision. Most tank manufacturers use external dimensions to claim volume. It overstates actual volume.

if you mixed the calcium chloride in the brs 1 gallon jug then on the brs calculator click liquid calcium.

My experience is that calcium additions are much less sensitive than alkalinity additions. Not sure how many PPM you are trying to increase but I would have no concerns raising calcium by 50ppm in a single dose.

Well I guess I’m estimating, the rock and sump equipment make it hard to get an exact volume but BRS videos seem to claim that getting to within 10% is good enough.

Also displacement by glass walls! For example, my last mass market tank was a marineland 265, yet it actually only held 230 gallons. 41.6 grams just seems remarkably precise …. seems incongruous to '10% in good enough'.

Easy equation for calculating your actual maximum water volume:

Tank length x width x height (excluding glass thickness) in inches, divided by 231, equals volume in gallons.

I don't recommend boosting calcium more than 25 ppm per day. I do not know how much solid material that corresponds to in your tank. Dissolve it in freshwater and add to a high flow area away from corals. Slower is never worse except in emergency situations.

And remember that height is water height, not height of the glass.

Thanks but accounting for the rock, sand and pumps in the DT and the equipment in the sump make it difficult calculate the total water volume.
