Red algae

[Slyguy00]

Thanks for all the input. I will be getting a new test set next week. I need a more accurate mag, all and calcium test anyways. Hagen six. I will deff be looking into that mb7. And really? You think it would be more beneficial to my tank to do 10 every two weeks instead? why is that?

You get a bigger vol turnover in your tank with 10 g every 2 weeks instead of 5 every week. Do the math.

Or think of it this way. If you changed 50% of your tank every week, or 100% every 2 weeks, which will provide a more complete turnover of your water? Of course that is not practical or recommended, but just wanted to use that example to help make the point.

Makes perfect sense. I will start doing that next time. Thanks for the advise!

Yup, red slime and cyano are one and the same

Looking into it further, I think I may be running my lights way to long as well. I believe that could be an additional reason as to why I have cyano bacteria. How many hours a day do you guys run your lights?

Depends on what type of lights and intensity through the day. I run LED's in "Natural Mode" for 12 hours. But they ramp up slowly to a peak at "noon" and then back down through the afternoon and evening. I also have mine set for deeper water, so that reduces parts of the spectrum.

What are yours?
