Icecap in sump uv sterilizer placement questions

timiller · Oct 9, 2025

I recently bought the icecap in sump uv sterilizer for my sump. I did not want to replumb to put a uv sterilizer in line and the way I built my tank stand there isn’t really the room. I would have liked to put the drop in uv sterilizer in the return section of my sump but unfortunately it doesn’t fit in that section. Currently I have it in my skimmer section. I can run the return from the uv sterilizer over the wall into my Refugium section to put the water a bit closer to the return or I can leave it returning the water to the skimmer section. Thoughts? Thank you! https://docs.google.com/document/d/1006QCbLjyl63aBf1p0I4sgzUspVVpOr25vRgoxlSDag/edit?usp=drivesdk

interesting. I look forward to seeing how well it clarifies your water, or helps with Algae. Please keep us updated.

I have been eyeing this in sump sterilizer as well. Let us know how you like it and where you would buy replacement bulbs. I figured since it's still so new... The replacement bulbs have yet to be released?

Coralvue has them. I purchased mine from premium aquatics.
