Fish: Re: [tropical fish club] Re: Planted tank ?'s

I may be mistaken however I believe that muriatic acid is a dilute form
of hydrogen chloride (hydrochloric acid). Copper in any form,
hydrochloric or any other acid, is at best risky. I have been a fish
keeper for over 40 years and have never had to resort to these extreme
measures. Yes, I have washed out a few tanks in my day however I never
regretted doing that. It was a new beginning. If any of you readers
would like to see my handywork please mention it.
