Disappearing cyano algae

[Trigger Man]

If your bulbs are getting old it could be that. As the bulb ages its output declines.
When I had red slime issues I ran chemiclean Red slime remover (2 cycles). That removed all of my red slime and it has not come back since. I also use Aqua Connect Contraphos and find it has gotten rid of basicly all the algae in my tank (does not affect my coralline which I want on my lr) With the Contraphos, there are no english instructions, but basicly for my 125ish tank I started with putting 100 ml in the provided filter bag and putting it in for a week. Then I would change the media and put the new stuff in for a week. After 3 weeks I now change the media around once a month and have no algae problems. I tend to over feed so i know my fish are producing a lot of waste and some food just gets lost in the tank. So you can try the above out and hopefully it works for you if you still have the algae probs.
