water movement

Hi maknwar,
What kind of algae is occurring low in the tank? In my experience, cyanobacteria (blue-green algae) can be combated with water movement but if it is any of the old green standbys (dust, green dust, etc.), I would look more toward your fertilization regime than water movement. Also, is the tank new? I always get weird algae problems in new tanks, but things tend to stabilize after a few weeks. Good luck!

This raises an interesting question: we start up a new tank, get algae. So, we try adding X, still have algae. We add Y, still have algae. We change lights, still have algae. Time is passing and the tank is no longer so new. We finally drop a gum drop in the tank, algae goes away!!! We have a new algae prevention device?

I'm not just joking. I wonder how many of our successful efforts to get rid of algae succeed just because of the time that has passed?

Hoppy - what flavor of gum drop was that?.....

LOL

It has been set up for about a month, and the algae is small spots about the size of a pencil eraser. It was very hard to scrape off. I think I might just wait and see how fast it comes back. Maybe it is me not dosing correctly.

Were they just green spots on the glass? If so they're pretty normal, proper ferts and co2 keep it at bay, but I think every tank has some amount. Just scrape it off when you do a water change.

Do a search for GSA (green spot algae).
