I plan to use diluted muriatic acid for cleaning some pumps and a skimmer. Also I have a FW plant tank with a glass top that has opaque white lime deposits blocking the light, resistant to all other cleaners, so I want to so a diluted muriatic acid bath for it too.

Some questions about this stuff as it is obviously hazardous.

1. I have read 10:1 dilution 1 part acid added to 10 parts water, is that about right, will a weaker dilution work as well if I give it more time? I'd prefer to use as little of this stuff as possible.

2. Will the muriatic acid eat plastic parts on my pump or eat magnetic pump impellers or metal parts on the pump?

3. I have read to use the muriatic acid outdoors because of the fumes, is this a legitimate concern? I am assuming it gives off chlorine gas which obviously you want to avoid breathing in.

5. After using the diluted muriatic acid is it OK to pour it down the drain and flush with lots of water, or will it eat my plumbing pipes?

Obviously I will suit up with eye protection and rubber gloves. Any other tips on handling this stuff?
