Risks with high alkalinity?

[jenpen400]

Jennifer,

I just want to understand clearly. Are you now at an alkalinity of 110 or 220? Is the evaporation less because you've got the fountain on a lower setting? So now you have a balance between losing alkalinty through the aeration (and adding acid to restore the pH) and gaining alkalinity from make-up water for evaporation. Is that right? So your alkalinity is stable, but aren't you adding a lot of acid frequently to keep your pH down? I suppose that may be the tradeoff necessary.

Evap. --> Make-Up --> Alk. Up
  ^                       V
  |                   Fountain
Alk. Down                 V
pH Down <---- Acid <---  pH Up

Is that your cycle?

Last test alkalinity was 140 down from 160 due to lots of evaporation and high fill water. Yes this takes a lot of acid. What I have found is that vigorously aerating it seems I evaporate more water with out rising the ph faster. It could be that more water makes it over the side but the top rail seems dry??? When I get the alkalinity where I want it I just ripple the surface with the jet and even though I replace an inch or two a week it alkalinity and ph remain 110 and 7.5-7.8 with out adding much. I have never needed to raise my ph and my fill water has a ph of 7.5 Hope I did the quote thing right it's my first time.

Jennifer,

You did great. Thanks for the info. You may have hit on a procedure that may work well for people with high alkalinity tap water. We'll see how Rangeball does with it!

Just found out last night that we're having another kid fest Thursday night. Aeration x 100

I plan to lower my PH to around 7 pre party and let them have at it. I'll test the next morning to see where things leveled out.
