- sizes 14, 29? What is the volume? thanks
Answer by ChewyFeb 24, 2022
The volume for this sterilizer has not been recorded as it does not move any water. It connects to your existing BioCube pump. The dimensions of this sterilizer are 8.4 x 4.5 x 2.4 inches.

Can this be used in a 10 gallon tank

Worked awesome for 2 months then died

I was initially very happy with the Coralife Mini UV sterilizers. Super easy to plumb into my nano tanks and seemed to control the algae quite well. However, I noticed an algae bloom happening on my saltwater nano tank and realized that the sterilizer was not on. I opened up the case and found the bulb was burned out. The exact scenario just happened with the other Coralife Mini UV sterilizer that I had on my freshwater tank. Both sterilizers burned out almost exactly 2 months from plumbing into my tanks.

Short bulb life - great while it lasted

This worked well to help with my dinoflagellate problem in my 14g biocube. Sadly, the bulb burned out after just 4 months of use, and the price for a replacement is practically the cost of a new UV sterilizer unit. At this rate, the cost of the bulbs make this a bad investment...

Probably good for small tanks..

The tank we own is a smidge too large to be compatible with this sterilizer unfortunately. My husband says we'd need an additional part in order to get it to to be usable in our tank and even so I don't know that it would be much use since this is designed for use in smaller fish tanks. Despite my lack of research into this before purchasing, I do think this is a brilllant product with a great use. I am curious as to the light bulb replacement issue that others have brought up. I will use this when we get a smaller tank and new fish! Product received for free in exchange for an honest review.

i couldn't figout how to use the Universal adapter

I could not figure out how to use the universal adapter to install on my none bio cube tank. I asked Chewy how, and the directions chewy sent me didn’t include how to install the adapter. I was unable to use it. I received this product in exchange for an honest review.

The sterilizer i never knew i needed!

I was given the opportunity to try this CoralLife mini ultraviolet sterilizer and have to say I am very impressed! I love the packaging and the sleek design, but what I am most please with is how clear my water is since I have been using. My fish also seem healthier and less disease prone. Would recommend. I received CashBack on this purchase and participated in a CashBack program.

A Sterilizer I never knew I needed

I was presented an opportunity to try the Coralife BioCube Aquarium Mini Ultraviolet Sterilizer and was really impressed on how much this product has cleared up the algae in my tank. My water is clearer and my fish seem to be less prone to disease. I love the sleek design and packaging. Would definitely recommend to any Hobbyist! I received this product as part of a promotion.

Works great

I’ve had bad hair algae issues for a year and a half and have tried everything. I’ve only had this for a couple weeks and so far it has helped. Water is noticeably clear and installation was very simple.

Can’t use Universal adapter

I was not able to use the Universal adapter on my non bio cube tank. I couldn’t find the directions for it and the video chewy sent me didn’t include the directions for the adapter

Small, but mighty sterilizer

The mini uv sterilizer packs a big punch in a small package. you submerge it in a small household fish tank and it kills all of the harmful bacteria. it takes care of all of your basic algae control and is soo easy to install! I highly recommend to anyone just getting started in home aquariums!

No more green!

It gets the job done. It was a little complicated to install. Had to have an aquarium maintenance expert help me put it in. But it’s only been about a week and there’s a HUGE difference in my bio cube. No more green!
