| HI Bob,
If I was going serious about treating the water to lower pH and hardness I would buy a large commercial water softener and a large reverse osmosis system and blend the RO water 50/50 with regular tap water. This will be very expensive. 1st the commericial sized softner and RO unit will cost about $10 thousand dollars total. Also you will need about 6 gallons of tap water to make 1 gallon of RO water which you will mix 50/50 with tap water. So a 1,000 gallon water change will take about 4,500 gallons of tap water to produce 50/50 blended RO/tap water. You will also need at minimum a 1,000 gallon holding tank to hold the RO water until needed. |
