We have a titanium heat exchanger. I read through the manufacturers warranty and it doesn't mention water chemistry so we're ok there. I have disconnected the unit from the rest of the plumbing and replacement is scheduled for sometime next week. Thanks everyone for you replies and suggestions.

Thanks Dave. :)

Hello everyone! My Perfectemp electric heat pump just blew the other day and dumped it's oil into our pool. I have contacted the manufacturer and they have agreed to replace the unit as it is still under warranty. In the mean time, I have a major mess on my hands. I understand that the oil is...

Thank you very much!

During the long hot summer is it better to drain the solar panels or leave the water in them?

Because of what phosphate removers can do to the water! Make it even cloudier! If you sell to pool owners (with cloudy water), a product that makes their water even cloudier (even if it's only temporary) they are going think you are crazy and go somewhere else to get their water tested. And no...

Thank you all for your responses and support. I had told the customer that his cloudy water was most likely caused by a nascent algae bloom due to his water test showing FC = 0 and a PH = 8.0 or higher. All other readings were normal. My colleague has no authority to tell me how to do my job...

Thanks duraleigh, for your response, none the less. I'm posting this because of what happened in our pool store today. I was testing a customers' water who was complaining that it was cloudy. I was told by a colleague to test his phosphates. I replied that I was not concerned about that. He...

Can phosphates alone cause cloudy pool water? If so, under what circumstances does that occur? Not counting the use of phosphate removers. "Phosphates are excellent plant fertilisers. They do no detectable harm in humans (in fact, phosphorus is an essential element for all known life). However...

Exactly, but I read somewhere that algae mistakes the monochloramine for food and consumes it. In the process, the compound breaks down into it's constituent chlorine and then the chlorine is what actually kills the algae. Can't remember where I read that though. Any more thoughts or evidence.

Have searched everywhere and cannot find any evidence that Aqua Ammonia (alone) kills algae. Anyone have any experience or knowledge about this?

Ok, let me rephrase the question. When is algae most vulnerable to be killed? by whatever means. Day or night? Or does it matter at all? I've heard some say it is best to catch it in the day when it's in full bloom. Others say at night when it's more dormant. What is their reasoning?

I say during the day as that is when it's blooming, but does the scientific data back that up?

Perfect! That's exactly what I was looking for. :goodjob: Now for my next question....

So is it safe to say then that elevated PH, Alkalinity, and CYA are more likely to result in cloudy water when CH is added than if those numbers are lower? Are you more likely to see cloudiness when you add chemicals that raise these numbers, on the same day you are adding CH? and less likely to...
