When Gerald and Sophia were re-installed after the move to The Tapestry building, I believe that normal tap water was used. Since then, i don’t Believe either cooler has been topped off, but this should be done soon (and may also address some of the issues with Gerald when he has been running all day).

I have found an interesting article on the web regarding laser coolants

https://lasergods.com/laser-water-coolants-additives/

So I was going to suggest that we replace the coolants for both Gerald and Sophia using the methods suggested in this article, whilst also topping up the coolant levels at the same time.

Does anyone know what the coolant capacities are for the two chillers, so that we can order the right quantity of distilled water?

I have found quite a few relatively local suppliers of distilled water on eBay, whereas web based suppliers seem to quote a lot for carriage.

Issue #106 shows we've got CW3000 and CW5200 chillers. This manual for the CW3000 says its capacity is 9L, and this manual for the CW5200 shows a 6L capacity.

I don't know if they do distilled water, but we used to get deionised water (which I suspect is what HPC told us to use) from Mersey Batteries on Jordan St in the Baltic Triangle (see #78 for details)

The article I linked to suggested that deionised water isn’t as good as distilled water, hence my suggestion. We also need something to kill any algi that may accumulate in the water, as the water is a little brown in Gerald at the moment for example. I suspect we can pick this up from an aquarium shop, or online.

Reverse osmosis water from a tropical fish shop is cheaper, plus I have a conductivity meter I can bring in to check it with if required.
