UV Light For Freshwater Aquarium - Necessary? (#KaveManClips)

I have to say though this past month I had a major issue after a big water change that resulted in "Green" water and it was getting worse, then I got a UV kit and in ~4 days I think the water is cleaner than it has ever been. But I also agree I probably went overboard on the cleaning previously.

Great video as always

Kev, I saw your posts on IG when you were doing some water changes. I wanted to ask why and how do you use an external pump? Is it just to push water out faster? Do you gravel vacuum separately then you change your water? Great content btw

Like always great info thanks for the time

Awesome video snippet; Kev. I think I have a fairly healthy balance of not keeping the light on for more than 3 to 4 hours a day (planted tank) and I’m really trying to watch how much I feed my fish but they are super active fish.

I got a 40 breeder next to a window & would stay green. Put the uv on it & is crystal clear now

I had an algae issue on my african cichlid tank, the phytoplankton. I blacked out the tank for 2 days with only a side wall portion uncovered with only natural light coming in the tank. It cleared out the water completely. Now i’m running the fluval with Kev’s advice on media choice and have not had an issue since.

The fluval in line clarifier is on point

Hello, I love your informational videos. Keep up the great work. I do have a question and would like to get your thoughts. Is there any brand of canister filter, who states accurate and "actual" GPH specifications of their filters? The reason I ask this, is because I have experienced an issue with Fluval and in my research to find a resolution, it appears that all manufactures of canister filters are doing the same thing. That is over-rating or over-spec the performance of their canister filters. I have had a eastern painted turtle in a 75 gallon aquarium, (with only 40 gallons of water) for 20 years. My very first canister was the Marineland Magnum 350. I eventually replaced it with a Rena XL which I had for 15 years, until the motor housing got a large crack, and began to leak. So, I replaced the Rena with a Fluval 407. As soon I began using the Fluval 407, my water soon became cloudy. It appeared like Biological bloom. Yes, I used all of the bio media from the Rena in the new Fluval. I also added bio additive to the water and still the water has become cloudy and will not clear. Over the past FIVE (5) MONTHS I have tried everything to resolve this issue and have talked to several aquarium professionals. During my research to find a resolution for this problem, I found articles and videos on flow (GPH) test on various canister filters, which has shown that many canister filter manufactures severely over-spec their canister filters performance. So I decided to check the Fluval 407 that I had purchased, to see the actual GPH that I'm getting with this filter on my aquarium. First I installed new mechanical foam filters, rinsed the bio media and cleaned the hoses. Then after purging all the air from the filter, I removed the diverter from the outlet hose in the tank and performed a flow test three (3) times. Then I removed all of the foam sponges, bio media and re-installed the motor head to perform the same flow test with NO filters, media or baskets. Just an empty canister and the pump head and performed the same flow test three (3) times. Here are my test results: Flow test with media - 134.64 GPH. Flow test WITHOUT media - 152.58 GPH. According the manufactures specifications, the pump output has a max of 383GPH. The max output of the canister filter WITH MEDIA is 245GPH. I understand there are many factors that will effect flow, like hose routing, pump distance to the water and distance from the top of the water to the rim of the tank. My set up matches Fluval's recommended set-up and configuration and yet I still had very low numbers. So my final test was to raise the canister filter closer to the top of the water in the tank, creating less resistance against the filter pump motor. My final test indicated only a 10 GPH improvement over the first test I have been in contact with Fluval and they insist there is nothing wrong with the filter and that it is working correctly. There only suggestion is to install a UVC Clarifier in line with the pump. And Yes, I have checked the water condition. All the levels are excellent, nitrate, nitrite, ammonia, etc... In the twenty years I have owned this aquarium with this one 6" eastern painted turtle, I have never had a cloudy water issue, until I installed the Fluval 407. I have looked at other brands or models of canister filters to install in place of the 407, but many have a lot of bad reviews with leaks and failures, are too small or too large or are difficult to find replacement filter for. Your thoughts?

My name is Mark from Tampa Florida I just want to thank you for the advice you gave on Algae blooms. I followed what you said. Now my 125 gallon is crystal clear

Can you do a video on fish flashing ? And what’s normal and what’s not ? And when to be concerned

Top advice asAlways Kev👏🏻 when are you planning the next live.? Awesome participation last time

good tips

I found that for me it was the filter. No matter what I did the water was green and then I read somewhere that the filter needs to filter the water in the tank at least 4 times per hour. Mine was not doing even close to that, but that's what I was told work work for my tank when I was at the store. I changed the filter and have never had any problems since.

thank you

Thank you for the video. It's possible to use aquarium UV light to sterilize drinking water?

I'm dealing with fish TB AKA Mycobacteria, I'm not happy. Lost my Flowerhorn a couple of months ago, had no idea why but I wasn't aware of fish TB until about a week or two ago. I'm considering using a UV sterilizer. Do your research on this folks.

My issue is brown algae/diatoms. I do weekly 75 percent ish water changes. Vacuum extra food after feeding daily. I use prime and running a Fluval 407 on a 65 gallon. I kinda like the green algae ( fish munch on) but the brown on decor is annoying. Thinking of an in-line if sterilizer may help. Any thoughts?

I installed one a couple of months ago haven’t turned it on yet plan on using it mainly for parasites ,not for waterclarity .like Kev says u will get some type of parasite eventually,so I have it mainly as a preventive or to help when a problem does occur
