IntelliChem with Acid and Chlorine Containers

[tejobrut]

I just had IntelliChem installed with acid (521378) and chlorine (521398) containers, which have with small vent holes.

The whole system is enclosed in the equipment shed, which has an 8" wide chimney through the roof and two 16"x4" openings at where the roof meets side walls.

I got a few questions:

1. Do I need to add additional ventilation fan?

2. What MA concentration should I pour into the acid container, 31% (pool store) or 15% (HD)? If I need to use lower concentration, for example 15%, can I wait until the container is completely empty, then pour water into the container and lastly pour 31% MA?

That should be enough ventilation.

You want 3 to 1 or 4 to 1 water to acid (based on 31%). You don't need to wait for the container to be completely empty, just mostly empty, as long as you have a fairly narrow opening and keep your face away from the opening when adding either water or acid.
