This came fitted in the koi pond when I bought my house. I don't know if it needs filter or UV bulb replacement. Is there an indicator for these?

it takes 4# filters inside which can be purchased from Amazon, we have so far not had to replace the UV bulb, but the indicator is located in a small bubble raised area on the top of the filter. It's a great unit for keeping the pond clear. we generally pump it at least once a week to keep everything flowing.

There is a small clear lens on the top. Look at it very closely with your hands eliminating as much light as possible. If it is not shining, the bulb is out. As for the filter, there is an indicator for that too. Go to the Laguna site and it has all of that information and instructions on how to change the light. It is important to it is done correctly.

You CANNOT see the UV light. When the UV light is engaged, there is a bright blue indicator light. However, this is not the UV light. The blue indicator light will not damage your eyes or skin. The actual UV lightbulb is mostly protected from exposure inside the filter's housing. I believe the warning in the instructions refers to viewing the light when the purifier is disassembled.

There isn't a marker or indicator. However, the water flow will slow down. I change mine about once a year.

From my experience, 6 months seems to be a reasonable time to have the UV bulb, now if you notice the water quality diminishing that would be a good sign that it's not working, but that's my experience anyway. I have had success by regular tank management (weekly 5 - 10 % water changes), sea salt, combined with the bulb have been fine. No problems.

I will be very honest with you, this unit I got, the UV light shorted out or burned out. But they replaced the whole unit for me. However, I did not get the same one with the UV in it. So I have never replaced the bulb! I had no problems with the company & recieving my replacement filter. I don't know if this helped you or not.

I spliced the wire into an existing low voltage line and double heat-shrinked the connections, since I used it submerged in a koi pond. The light worked fine for a while, but quit. When I pulled it out it had water in it. I added a bunch of silicone around the wire and let it cure. Also replaced the bulb and tried it again. Same result, it quit working after a short period. I think it's leaking around the lense. The o-ring doesn't seem very resilient and appears to have relaxed against the glass. If you are using it around a pond, not in it, it might be okay.

I would take out the filters from behind the UV lamp and then put the back on the unit. When you turn on the unit the UV violet color should show through the back fins of the case. If not then your UV light could be not working.

I am not sure, the right one is filling with water, the bulb size sounds right

I didn't see a line on my screen after replacing the lamp & housing. I will speak to the other comments though. The OEM lamp & housing did not have SONY printed or etched anywhere on the unit & I suspect SONY contracts these out to the lowest bidder anyhow. My replacement has performed flawlessly & is much brighter than the OEM part, as I would expect from a 8-9 year old part. I have had the replacement for about 2-3 weeks, so I can't testify about longevity yet. I'm completely satisfied to save $200 on a bulb!

no, not to replace the bulb. If you are replacing the lens, then yes you need to lower the water level

It is supossed to be out or low on water but mine is also showing F. I think I need to change the filter before it will go away but I am not sure.

After using mine for about a month I also noticed the same thing and had this same question. It was like that right out of the box. After researching the manufacturers website about this product it became clear that the red light means a burnt out UV bulb. The bulb cost as much as the whole filter and was not available so I trashed the whole filter. This is clearly not a quality product. Check www.aa-aquarium.com and see what you can find out.

There is a small door on the side of the lid. Open it and you will find the UV switch. One of the respondents wrote that he experienced melting. A broken or loose bulb can create a short. Make certain that your wall outlet has a GFCI. This will cut the power in the event of a short, and keep you and your fish from being electrocuted. Water and electricity don't mix. Pick this up at a big box store for about $10, or call an electrician. But don't run your tank without one.

No there is not an indicator. However, the filter only needs to be change every year or so, so I usually made a note for myself and taped it onto the filter holder under the sink. You can also get on an auto-replacement filter mail order system.

The place where I bought the UV light from did at one time sell replacement bulbs. You'll have to contact the site to see if they still do

As others have mentioned, the UV light should not be used inline with the filter (to high a flow rate), but should be set up independently. It needs to be set up with a separate low flow pump. (These are not very expensive.) I had trouble with my water turning brown due to an algae. The UV light cleared it up nicely.
