Great to see these video's get updated every so often. New people to the hobby, and people who don't see things often can keep refreshing our knowledge

I wish there was more consistent information regarding established tanks suddenly becoming cloudy. Every youtuber has a different opinion. Makes it very difficult choosing what to do.

Currently experiencing a bacteria bloom so this was perfect timing in my world! Thanks!

[kasperaquatics]

Excellent info Zenzo, always a huge help to the hobby.

You must have read my cloudy mind. Timely video

[cookiemonster]

Thank you very much, my week old cold water aquarium has been cloudy, I did a water change and it became cloudy again 24hrs later, due to your vid I now see it was good bacteria and I will leave the water to clear itself, thank you 👍🇬🇧

All i can say is all of the videos that i watch is full of learnings about fish keeping i love it

[StanLeesReviews]

Thanks for the information much appreciated

[mbastos]

Thanks. I believe I have bacterial overgrow in my fish tank. It looks like a blue cloud color very thin in water column. O have as substrate organic soil capped with playing sand that I washed before using it to cap the organic soil. I realized that it gets worst when I clean the hang on filter. Probably, I am killing the bacteria in the sponge and media of the filter despite I don't use tap water neither spot clean the sponges. It is not green water. It is more like cloudy light blue.

Wow! I’m going to have to watch this awesome video a few times because it’s full of important information ! There is so much to learn ! Thank you for this concise and interesting video on cloudy water. I always freak out and do water changes When my water gets cloudy - I realize now I should check the ammonia, NO2- & NO3- then if reading are dangerous to inhabitants- only then change water- I might be resetting my cycle and that’s why I’m still trying to cycle my tanks. My tanks were started Jan, feb March May 2023. I’ve never had fish tanks prior . I can’t imagine everyone has such a hard time stabilizing water?

One of the most overlooked reasons for having cloudy water: insufficient biofiltration. Biofiltration isn't just about the nitrogen cycle; after cycling, over the course of months a complete ecosystem will develop containing nitrifying bacteria, but crucially also heterotrophic bacteria and a lot of other microorganisms feeding on waste, on pathogens, on each other, etc.... The thing is, your filter media needs to offer a lot of surface area, and the media should be cleaned as little as possible. Many people either overclean their filters, use inefficient filter media or both. An aquarium that is "overfiltered" will have very clear water, and the fish will be much less susceptible to disease. This is because the bacteria on the filter media outcompete those in the water column, leaving much less bacteria for the fish's immune systems to fight off.

You can count to your fingers on how many times of getting cloudy tanks, bacterial bloom, algae bloom for since I started 2013...Having a Efficient filtration system...Very Informative...

Hey Cory. I didnt get a chance to make it to Aquashella but my dad did. He brought me back one of your shirts. Thank you. All your knowledge has helped both me and my dad.

[GENNY]

Thank goodness I watched this my water was milky gray water and I thought the water was getting dirty but all I had to do was let it be, thanks for the advice

[RenegadeLK]

After shifting some of the gravel in my 10 by accident it's starting to look very cloudy with a bit of green color. A few weeks now passed and it looks like I'm gonna have to try some of these methods.

[SelfDescribed]

Thanks for the video. Can you guys do a video on aquarium micro-fauna? I've got some brown algae in my planted tank and it looks like I got some copepods munching on the algae. Do I just let them do their thing?

[karenmccleary]

Thanks for the info! Would like info on your goldfish tank… size and how many fish are in there?
Thanks

[Pezzer]

Set up a fish tank yesterday woke up this morning to cloudy water not experienced it before as I had tanks as a kid so wondered if I did something wrong as it was my first time to use bacto start I now know I just have to leave it to do it's thing thank you.

[ridesnvibes]

I recently had algae issues (brown diatom and green hair algae) and despite me cleaning the algae off during weekly water changes it would come right back. I did two things after making sure it wasn’t my water parameters. I got two mystery snails and I bought the TopFin Pro 30 Power Filter Media Pack for $6 to replace the standard carbon filled cartridges that come with most HOBs. It’s two days till water change time and the algae has not come back and my water looks clear as ever. I think it’s the media pack doing most the work while the snails stay polishing up the existing algae. Hoping I finally figured it out!

I know that having a light on too long can affect algae blooms, but do blue only lights cause the same thing? I have a light that has the option of full spectrum or blue only and just not sure if using the blue only is going to be the same as having the full spectrum on.
