Wow!! LIGHTBULB MOMENT!!! I've often wondered why sumi finishes better in harder water. But what about the HI? Isn't a high PH and harder water harder on the HI? I would appreciate much more discussion re this topic please!! Here to learn!!
So if I'm to understand the initial summary. If your pond has a higher PH and silicone in the water you are likely to have more stable and better sumi? OK so if you add calcimum bentonite clay to the system, does that count?
...Oh, and lots of 02 also....
