My aquarium is cloudy and smells bad. Will the UVC clarifier help?

If the cloudiness is due to suspended bacteria or algae, the UVC clarifier will indeed clear the water, provided it is installed as instructed. To help reduce smells, the best solution is the use of activated carbon. It is also advisable to investigate the source of the odor: if it is due to decomposing organic matter make sure to remove it and perform a regular partial water changes.


Does the UVC clarifier prevent algae growth on surfaces within the aquarium?

The UVC clarifier will only neutralize suspended bacteria and algae, and as such will not prevent the growth of most algae on the aquarium glass, gravel, dΓ©cor, etc. Some surface-dwelling algae species exist as spores at some life stages, however: the UVC clarifier will help prevent the growth of these species.


Will using the UVC clarifier harm the beneficial bacteria in my aquarium?

The beneficial species of heterotrophic and nitrifying bacteria in an aquarium live on surfaces in the filter, in the substrate, on plants, etc. They do not live in the water column and as such are entirely unnaffected by UVC sterilization.


Will the UVC clarifier have any negative effects on the beneficial microorganisms in my reef aquarium?

The UVC clarifier may affect some beneficial microorganisms present in the water column, including ones that may be a food source for some species of fish and coral. In healthy reef aquariums, however, these microorganisms are very abundant and the UVC clarifier won’t significantly affect their population levels.


Will the UVC clarifier help keep my fish from getting sick?

The UVC clarifier helps to keep aquariums clean and healthy, but it is not a treatment for sick fish. Always consult your local aquatics retailer for assistance in preventing or treating aquarium fish diseases.


My fish have ich, will the UVC clarifier cure them?

In general, parasites are too large to be effectively terminated by UVC light. To treat ich, we recommend consulting your local aquatics retailer for assistance.


I am treating my fish with medication. Should I continue to run the UVC clarifier while doing so?

In order to ensure the most effective treatment, the UVC clarifier should be unplugged while medicating fish.


How do I know the UVC clarifier is working?

The 24-hour timer features an operating status light. If it’s green, the UVC bulb is functioning normally. If it’s red, the bulb has expired and the UVC clarifier must be replaced.


How long should I run the UVC clarifier for?

We recommend first running the UVC clarifier intermittently, for 4 hours a day. If the desired effects are not achieved, gradually increase the amount of time the unit runs each day until they are.


How will the UVC clarifier work following a power interruption?

The UVC clarifier will revert to the same operating time that was initially selected once it is reconnected to a power source. For example, if the timer was set to operate for 4 hours a day, it will continue to operate for 4 hours from the moment power is re-established. As the timer does not keep track of the time of day, if you want the UVC unit to run for 4 hours a day as of 8 am, for example, the unit should be connected to a power source at 8 am.


What size hosing does the UVC clarifier accept?

The UVC clarifier connects in-line to all canister filter hosing with an internal diameter of 5/8β€³ (or 16 mm), such as the Fluval 07 series.


Does the UVC clarifier need to be mounted with the mounting screws or can it hang in-line with the hosing?

We strongly recommend mounting the UVC clarifier with the two mounting screws provided. The unit should be mounted vertically, with the hose connections at the top and the mounting screws at the bottom.


Is there a particular orientation the UVC clarifier should be mounted?

The UVC clarifier should be mounted vertically, with the hose connections at the top and the mounting screws at the bottom.


My filter stopped operating for a few hours but the UVC clarifier was still plugged in and working. Is it safe to continue using the unit or does it need to be replaced?

The unit is safe to continue using.


I accidentally dropped my UVC clarifier. How do I know if the bulb is broken? Should the unit be replaced as a precaution?

It is not possible to open the UVC clarifier to verify if the bulb is broken. As such, we recommend replacing the unit as a precaution.


What makes a CCFL bulb better than traditional fluorescent bulbs?

A Cold Cathode Fluorescent Light (CCFL) runs cooler than a traditional fluorescent bulb and as such lasts up to 3 times longer.

AWESOME Look and Quality
Color: Brown, Size: 2Tier60in
I love these shelves and have bought additional for other areas in the house. I love the look of the industrial pipes, the color of the shelves is perfect, they are sturdy and hold a lot of weight. They are somewhat difficult to assemble, but it's expected as hanging shelves are never fun to hang. I love them. If you are on the fence, just do it :)

Nice, but a bear to install
Color: Black, Size: 3Tier48in
Quality product that looks good on our shiplap wall of the wet bar space. The install was a real trip and extremely difficult. You definitely need 2 or more people to install as the direction tell you to put the entire item together, then hang on the wall. This makes it impossible to do yourself.

Exactly what I was looking for
Color: Brown, Size: 3Tier48in, Color: Brown, Size: 3Tier48in
Very sturdy shelves and super easy to put together. I would put the shelves together starting with the bottoms then after it’s put together tighten everything up also starting from the bottom.

Great buy
Great shelf base! The price is great and it does the job. I just got the actual shelves from Lowe’s and they work great. I used for my teen son’s room and he loves them!
