Several of my kegs are getting low now so time to brew another batch or six. First job is to replace the exhausted de-ionisation crystals in the 4th stage of my RO filter. I use colour changing crystals so you can see when they need replacing. When new they are very dark green, almost black. When they need replacing they turn orange. Here’s a picture of the exhausted crystals and what I’m putting in (same stuff).
To replace the crystals, remove the 4th stage, open the top and tip out the old crystals, strip down the components and give them a rinse off. Fill with fresh crystals, reassemble, and refit the 4th stage. Quick and easy. Now for some water for tomorrows brew.
