Arcadia Ultra-Seal Replacement Rings, 25mm, AB8R

Does the job, tank light up & running fine. Prompt delivery, good delivery info.

I have been running two Acadia T8 lights in the sump of my reef tank continuously for over ten years. A couple of weeks ago the tubes failed and needed replacing. When I was removing the tubes the Ultra Seal Rings cracked and were no longer providing an effective seal. I purchased new seals from Internet Reptiles( thanks for your prompt response and delivery) and renewed the tubes and seals. The seals fitted perfectly and the lights are on once again,
hopefully for another 10 years. Tip - use a little vaseline grease on the seals and threads when re assembling.
