Running the line to the back of the tank would involve some very complicated plumbing and 3-4 walls to go through. 15' is across the room as the crow flies, but I will keep this in mind when designing the future house.
I'm OK with adding the tap and just unrolling the hose. My wife is going to think I'm crazy for adding a garden reel inside our basement closet.
Understood with the WC for C02 and higher ferts. I must have read your dosage wrong as I thought it was very similar to the regimen from Tom Barr.
I'll get the torch out tonight, make the modification, try not to burn down the house, and test the well and soft water (for kicks).
Might as well add a storage shelf in the same closet for all the aquarium supplies while I am at it (nothing pretty, as I keep the door closed).
Next step - since this is all softened water now, should i replace the current setup with the new water over the course of a few weeks with 25-50% water changes?
