Slimy bastidges, with apologies to J. Dangerously.

Post by fred ungewitter » Fri Jan 06, 2017 2:18 pm

As part of the process of replacing my failed laser tube, I drained the cooling system. I discovered that my water pump residing inside my modified office cooler has a thin layer of slimy organic material. I discovered that the silicone tubing has a similar non-transparent layer of slime. The tube itself is spotlessly clean, but that's not to say it's slime-free.

My home-spun cooler refrigerates well and was quite inexpensive for the amount of cold water it can produce, but the surface of one bucket is open to the air. I'll be modifying that soon, adding a filter as well, but have ordered something else to add to the system.

Low price, high power, domestically shipped, I'm hopeful this will reduce the growth of any organic material inside the system:

Interesting idea. Please let us know how it works for you.

I have read about different substances people use to ward off algae but it seems each one has a drawback.

I'd done some research to see about algacides and various forms of antifreeze for laser cooling systems. It seems that unless freezing is an issue (not here), antifreeze isn't recommended. I don't want to use any chemicals that might interact with the insides of the laser tube, silicone tubing or my water cooler, leaving UV exposure as an option. At the very least, I'll be wasting electricity and nothing else will happen. As long as I get plenty of sunshine, my laser systems are solar powered!

I have just fitted 3 large aquarium filters to my 3 water tanks, What a difference, 3 clean clear non slimy tanks, I'm sure this is the best, easiest and cheapest option.

Do the filters use re-usable or throw-away filter elements? Are these perhaps some form of charcoal filter? I am considering also to install a filter of some form, to compliment the UV sanitizer.

Malcolm -

I am guessing you are using a large reservoir and aquarium pump as your cooling system at each laser versus a chiller with a smaller reservoir?

29 US gallon tanks would certainly do it! :D

Have you found out anything about using chlorine? I have two gallons in my tank and was planning to try 1/2 teaspoon of Chlorox. That puts it right at the EPA limit for human consumption, which I figured was safe place to start.

My last tank of water got slimed while I wasn't paying attention. I've since changed it, but I still have some residual algae left in the tube...

Chlorine reacts to the extreme with aluminum and likely with other metals. I would hesitate to add any chlorine to water in the laser. In my research and "travels" on the 'net, I found more posts saying no chlorine than I did for using the stuff. I'm hopeful the UV sanitizer is at a non-ionizing level, as I don't know what ionized water will do to the system. I don't know what ionized water is.
