Hi
@Fish are friends
Eighteen months ago, I began an in-depth investigation to try to identify the factors that contribute to the growth of Cyanobacteria. I don't claim to have solved this mystery but I have a far better idea of what some of these factors are. Here is a list (in no particular order):
1 Water pH - scientific research has demonstrated that Cyano prefer alkaline water. This is because they prefer to use carbonates and bicarbonates as a source of carbon, not CO2.
2 The water nitrate to phosphate
ratio is very important. I recently eliminated Cyano from one of my tanks by allowing phosphate to be completely exhausted. There was no livestock in this tank and some plants suffered as a consequence. Completely eliminating one of the plant nutrients would be bound to have this effect. Having resumed addition of phosphate, the plants are now recovering.
3 Cyano are susceptible to the effects of what are known as oxidizing agents but caution must be exercised if using these compounds.
4 Cyano need iron and are equipped with 'machinery' to enable them to extract this from the aquarium.
The list goes on.
Dependent on how far the Cyano has progressed in your tank(s), I have found Easy-Life
Blue Exit to be effective. Please supply a photo so that we can see what challenge lies ahead.

Hi Folks, Like many other aquarists, I have had cyanobacteria (aka 'BGA') grow in my tanks. And I started reading about this stuff. Of course, I initially thought BGA was algae. Why else would it be known as BGA (Blue-Green Algae)? But I later discovered that it's not an algae at all. It's a...

Now, I'm very much aware that some people will dismiss everything I've said above. But, if the Moderators are in agreement, I am happy to continue this topic by PM.
