I need to keep the front tile of the swimming pool open for the next one or two weeks to prevent the dog from walking on the pool cover (he knows it lowers into the pool if he puts weight on it). This way he just walks down a couple steps, cools off, and runs back out.

The exposed part of the pool will contribute to depleting chlorine/algae growth, so I hung a gallon gug 1/3rd filled with cal hypo and holes drilled into it at the deep end of the pool. Will that help offset algae growth over the next 1-2 weeks until we are ready to open the pool/launch the pump?

So far the pool does not look to have become very green over the winter and I don't want to waste the water.
 
I pull up the corner of the cover and put the sump in. while it is running, just pour chlorine slowly into the roiling water. You can keep FC up this way.
Post a full set of results. FC, CC, pH, TA, CH, CYA.
 
You test and maintain FC, yo you know the dosage is accurate and you can maintain FC for your CYA.
The chlorine will be diluted and not do damage.

Adding cal-hypo in the fashion that you described is very non-standard and would not be recommended.
You don't know how much chlorine it will add daily. With limited flow, it is possible to have highly acidic water around the jug and all the walls, potentially damaging.

I see. I hope the fact that I am keeping the jug basically in the middle of the deep end will mitigate most of this.
