I placed a UV light directly in my eshopps sump for a week. The eshopps site says they are UV resistant and I read acrylic has a 3% degradation to UV over a decade of sun exposure, so I thought it would be ok. Today I noticed hundreds of small cracks in the acrylic that must be from the UV light because there is no damage in the circular area which was where the suction cup was for the UV light. Is this just cosmetic or has the acrylic become brittle?
