BTA's and flow

[Zach117]

I started getting brown algae on my sand recently. It is an established 29 gal tank for about 1 yr now. I heard the best way to get rid of this is more flow and phosphate removal. I have a hang-on skimmer and AC 200 filter that create a small amount of flow. Every time I try to turn my Rio 600 on in any part of the tank the flow makes the BTA all stringy and he looks like he's about to get blown away. Is a smaller powerhead the answer or should I try and test my phosphates? Thanks

You should test your phosphates - if the BTA doesn't like the flow it will move. Is your other parameters ok?

All other paramaters are ok:
ph 8.3, ammon- 0, nitrate- 0, nitrite-0, Alk - about 9. It is hard for him to find a spot that their is no flow and I have put the powerhead as far away in the tank as I can.

i forgot - Alk is 9 dkh
