This is really great video, I advice everyone to watch it.
For you busy folks here are some indexes
Min 12: U need to remove chaetos regularly to effectively remove nutrients. That's one of the reasons some times algae reactors users will say it's not working even thu chaeto is growing, its because they do not remove the chaetos frequently.
Min 15: Adding liquid carbon to the water to grow bacteria like vinegar or sugar, you are assuming your system is carbon deficient which is not easy to know. It also assume you know which bacteria you are growing, you can actually start growing cyano as an example.
adding carbon without enough po4 and no3 will be problematic
Min 16: air fresheners can cause white bacterial film. This reminded me of an issue a user here called gabe dealing with white fungus like films on rocks.
Min 17: a good study refrence about bacterial count..that was very interesting cause its showing that our aquariums have 1/10 the bacterial population in natural coral habitats due to our mechanical filtration especially skimmer and activated carbon
Min 20: uv did not have a big impact on bacteria which kind explain why cyano and dino is not effectively treated by uv.
Min 21: If you add suger without enough bacteria in the water you will promot growth of algae and other unwanted bacteria like cyano
Min 22: cyano bacteria get their nitrogen from the atmosphere, so when add carbon and suger in a very low no3 system but some po4 availibity, cyano will thrive cause it will get its nitrogen from the air while nitrafying bacteria cannot so cyano wins...this explains alot some situations that are common where if you bring down no3 to zero but po4 is high cyano pop up...
Min 24: in high nitrate but zero po4 environment no3 will not go down even if you add bacteria cause the lack of po4 will prevent the purified from nitrification.
You can do some deductions in to why people adding random carbon sources or bacterial sources without really understanding their system brings with it the common algae, cyano and crash situations.
Ine of the reasons I like zeovit is that they force you to depend on the coral look and system look when deciding the dose. They give high level guidelines but they tell you the dose will vary based on how coral look and react and I think this is because carbon and bacterial dosing cannot be prescribed precisely without knowing the system...
