Pool Heater Chemistry

This blog post is about the chemistry of combustion, not the chemistry of the pool and spa water that is being heated.

Combustion:

Pool and spa heaters burn either natural gas—typically methane (CH4) or propane (C3H8). Since both of these fuels are made up of the same basic stuff—carbon and hydrogen, just in different proportions, the combustion reactions are going to be similar. For the sake of…

Using an Intelliflo pump with and AquaLogic or ProLogic Control System

Even the newest versions of the Hayward / Goldline AquaLogic controller (2.85) are not setup to select different speeds on the Intelliflo Pump.

It is possible, however, to get the two to work together using the first generation Pentair IntelliComm.

Programing the Pump:

First, set up four distinct speeds on the pump. This is straight forward on the old style 4 X 160. If using a newer menu…

Is the Saturation Index always Reliable?

When calculating the Saturation Index (SI), does a single low water parameter such as calcium hardness (CH), or a low carbonate alkalinity (C-ALK), make the water automatically aggressive to pool plaster, even when other water parameters are high enough to balance the SI? 

To answer that question, an experiment was conducted. Two quality pool plaster coupons were made and cured in balanced water for 90 days.  At that point, plaster coupon #1 was placed into SI balanced water, but with…
