Cyanobacteria (Blue-green Algae) - About and How to Get Rid of It!

Wonderful content! Why isn't this channel more popular? Some of the best aquarist content on Youtube. Keep going! You're raising the bar!

I don’t often comment but this is genuinely a really good video. You brought sound biological logic before each of your points. I’ve been keeping fish for a while, which means I’ve been watching videos for a while, and this is one of the best.

Listening to your videos is not only educational but also therapeutic! 👌 I get a lot of Cyano covering my sand substrate in 24 hours. I think it thrives in silicate.

Often people get into fishkeeping as a novelty pursuit "Ooh, look at the pretty fish" but when something goes wrong and tanks start to lose their looks and appeal, many of us initially look for quick fixes using chemicals and/or clean up crew. I like the way you explain the causes and science of the issue and your approach to dealing with it. I've come across the saying "we don't keep fish, we keep water" a number of times and it's true. We call ourselves aquarists, after all. Like you mention at the end of the video, these glass boxes with a bit of nature in them can often provide welcome relief from other aspects of life and (sometimes) there's as much enjoyment to be had from figuring things out as from when they're running smoothly. Edit: hmm, a bit philosophical today apparently.

God i wish this video came out sooner. I had this kill off my 75 gallon tank and was absolutely heart breaking. None of the fish stores had any idea what to do. Thank you for putting this out there

Appreciate your attention to detail and your informative videos. Keep up the great work!

By far the best advice on how to deal with cyno. Subbed!

Great tip on the turkey baster! I’ve got a tank I’m currently struggling with cyno, just gave it a pre baste before water change. Saved me damaging the plant leaves sucking them up the siphon ! Thanks v much

I just removed that same fast growing plant from my tank as well as an over-abundance of floating plants and then boom! Cyanobacteria is now taking over. What a mistake! Going to be adding more plants back in now. This video is very helpful because I was two steps away from buying antibiotics not really thinking about how that is a very drastic solution...

This is so well done. You just got yourself a subscriber.

I love how you say "fissshhhh" and "sssoup". Also very informative video. Thank you

I had a lot of success removing this with blackout boards for a few days. I remove as much as possible manually first then blackout the tank. Plants cope just fine with this.

Great information and video. Algae is a super organism, nature always finds a balance. 🍀

Could any of these methods be used to treat blue aelge blooms in the uk?

I had an outbreak, and the medicine I ordered came in today. I was about to dose the tank, but after watching your video, I’m elbow deep in the water picking the evil stuff out with a syringe. Good content!

Thank you so much! I’m going to try your suggestions.

Great approach to BGA! I'll add some fast growing stem plants, thanks for the tips

It's a big problem for sure. We use phosphate sucking exchangers on marine tanks and have found this helps a lot but your tank/s you show here are really thriving with cyanobacteria and maybe diatoms too. Good solid information.

Excellent video thank you

Great video. Definitely going to try.
