Did have a suspicion it maybe that. What can I do to get rid of it??
Oh so many assumptions coming your way.. and a topic thats been beaten to death around here with little to no real facts out of all of it..
Many think its too little flow, elevated phosphate levels, an imbalance of nitrate/phosphate, excessive DOC levels,etc....
For some (myself included) its seasonal and tends to come in the fall and leaves on its own without any extra work..
I've had it from slight strands like you have to 2-3mm thick mats covering every surface of my tank before..
Of all the attempted solutions,etc... there are 2 that actually stand out besides siphoning it out and these have been shown to actually do something in nearly all cases..
1-Lights out.. A 3 day lights out period is often recommended and in most cases "helps".. Notice I didn't say solves the problem.. Corals can easily handle a 3 day lights out period without issue and as this bacteria seems to feed off light too it is almost always "stunted" from the lack of light and sometimes thats all it takes..
I have done this and its worked really well..
2-Chemical treatments.. Some hate them and a few have claimed serious problems from the usage of such chemicals but many have used them with good results without any negatives...
The top 2 are Chemiclean by Boyds and Red Slime Remover from Ultralife
I have used both.. and both work well when directions are followed exactly...
In the 15+ years of reefing I've had cyano probably 15 times.. When I didn't just let it happen/pass on its own (I actually think its performing a beneficial process so I like to let it do its thing until it starts to negatively effect livestock,etc.. via smothering,,) I have used both 1 and 2 above always with good results and always do a good siphon before and after to get out as much as possible..
