I have been researching this one as well. I emailed H&G about the bennys in roots excel and tap water, because I have read their entire line is based on tap water use. This is what they said.

Potable water is treated with either chlorine or chloramines to keep it sanitary and drinkable, because the chlorine / chloramines kill microbes that can result harmful or fatal for us.
Some of our additives contain beneficial microbes in them. The chlorine or chloramine in the water will kill them! It is, therefore a good idea to aerate the water for a couple of hours before mixing in nutrients and additives--aeration helps dissipate the chlorine from the water, but not the chloramines! Chloramines will have to be removed with either a dechlorinator filter or a reverse osmosis system.I doubt your water has chloramines, but it always pays to ask your local water supplier.
Hope this helped!

This being said, my tap is 7oppm and I let it sit if I can. Watch out for additives because many use salt to remove chlorine. Nobody wants extra salt.
I use one of these!
Its supposed to effectively remove 85% of free chlorine from tap water! I'm not sure if it works with chloraminre but I will be aerating my water for 24hrs before use as an added measure! I noticed using water treating chemicals raised ph a lot! Just my 2 cents I hope it helps!
I have been to the rainshow 'r website. I like the sound of The Green Knight hydro dechlorinating inline hose filter and may try it out.
There you have my two cents.
