I put one gallon of muric acid in my swiming pool 24x12x5 say 35 cubic yards. It was to assist in the removal of the calcium that had precipitated to the walls and floor of the pool. I now need to reduce the acidity. Hence the question about washing soda, if this can be used what sort of quantities would be needed.

Washing soda, or sodium carbonate, is regularly used to increase the pH of a pool. I worked as a lifeguard for several years at our community pool, and when the pH got too low, we'd walk around the pool with a bucket of powdered sodium carbonate and put it into the pool (near the drains so it would mix in and be diluted). On busy days, we might have to do that a couple of times during adult swims.
The amount you need depends on the pH of your water, and the volume of water in the pool. Start with a cup or two, wiat a bit, then test your pH. Continue to adjst this way until you reach the desired alkalinity.

By washing soda, I'm going to assume you mean laundry (or other) detergent.
Anything alkaline will reduce the acidity. However, not knowing the specific brand of washing soda, I would also be concerned about any surfactants, degreasers, etc. which may be in the product. You may be able to correct the acidity but, in the process, create another problem, e.g. more scum and foam in the pool.
Something else to consider, if you reverse the acidity without changing the water, the calcium will likely precipitate again. Then you're stuck with your original problem.
My advice? Get a pH of the water and call a local pool supply shop for their recommendation. The best bet may be to drain the pool and put fresh water in there. The acidity AND the (currently) dissolved calcium will then be gone. Good luck.

washing soda? I'm from the US so are you talking about Baking Soda. Yes you can. Go to www.armandhammer.com. Go to Around the House. They have a pict. of a pool- click on it and it tells you how much to add
