Reddit mentions of Natural Chemistry 05141 Pool Magic Phosfree, 1-Liter

Here's what I use for my ~17000gal inground vinyl pool in zone 7 (PA):

• 1 L Metal Free
  
• 4 lbs non-chlorine shock (Leslie's Fresh & Clear)
  
• 1 lb chlorine shock (Leslie's Power Powder Plus) - sometimes less
  
• 1 Qt algae control
  
• 1 L Pool Magic + PhosFree
  
• 1 winterpill
  
  Here's my process:
  
  
• make sure TA is in 120-140PPM range
  
• make sure pH is in 7.4-7.6 range
  
• drop water line
  
• bump filter and drain it
  
• remove ladders, skimmer baskets, jet fittings
  
• toss any tablets that were in chlorinator, drain
  
• blow lines
  
• add 1 L Metal Free
  
• add 4 lbs Fresh & Clear
  
• if free chlorine is between 1-3ppm, add power powder plus to increase
  
• wait a day (high chlorine will kill algaecide)
  
• add 1 qt Algae control
  
• 1 L pool magic + phosfree
  
• put on cover
  
  
  In January/Feb (those weird days where it gets to be really warm) I'll throw in an aquapill under the cover. I forgot to use it this year though, and the water was fine.. but it was a pretty cold winter.
  
  Note: to circulate chemicals after lowering the water, I use my pool cleaning robot. If you don't have one, you can use a submersible pump, with the return hose going right back into the pool.
