Good morning. I'm on day 3 of owning a pool for the first time. I am following the "Beginners Guide for Seasonal/Temporary Pools" http://www.troublefreepool.com/pool-...ary_pool_guide found in Pool School. I have just one question at the moment, and that is concerning "Dichlor". I found what I think I need at Lowe's but the active ingredient is "Sodium dichloro-s-triazinetrione 15%", Is that the same as "dichloro-s-triazinetrione"? I couldn't find anything without the "Sodium". Am I good using this as my "pool shock"? Thanks in advance!
