Hmmmmmm. Maybe let him spend a fortune, screw it up, and then I can
save him! But, I will print up business cards first, "Dave's
Professional Pond Salvage". Then he will listen to me and I can
charge him big bucks!!

On another note. I have been very bad and not tested my water for a
very very long time. Seemed like no reason to. Was nicely surprised
that all parameters were near perfect. KH was a little low at 80.
With this heat, the biofilter must be working overtime.

Thanks,
Dave
