Hello all,
Hope you are all enjoying good weather.
The other day, I changed the UV clarifier lamp in my Laguna pond filter. I noticed, what looked like, blue crystals at the bottom of the lamp holder tube. I hadn't seen them before so I tipped them away. Does anyone know what they are? I'd appreciate any advice.
Thank you.
Chris Howard
