What is this

[CoryB]

I have tried chemiclean and it has done nothing. The directions say the water should turn yellow and it doesn't even do that.

It's brown and it's freakin everywhere. It's getting worse and worse.

Hard to tell from that picture but I would guess one of 3 things, hair algae , cyano or diatoms. How long has the tank been running and what are your params?

 

[CoryB]

It's been up for a year and a half everything is testing perfect. Always been.

I'm getting real sick of this ugly tank. Need help.

If you could show a pic with brighter light in the tank it will help more!

Bryopsis. Try using Kent Tech-M and raising your mag to about 1600-1700 (slowly).

Oh that's green hair algae for sure. The reason your not testing any nitrate or phosphate is the algae is feeding off it. Proceed as if the levels were off the charts( chemical media and lots of wc's) Try to pull as much of it out manually as you can. I've always had good experience with rowa phos for phosphate media, a bag of CPE wouldn't hurt either

I don't have a reactor so I am limited to the chemicals I can use.

Both can be run in hob filters

Mr_x what makes you think this? I've never had bryopsis ( atleast that I know of ) and would love to know the difference

Now that you say that a few months back I ran a hob with rowa plus in it and the pic above is the result but I can always throw it back on.

That's exactly what it is, and the Kent product will kill it off. Bryopsis is a broad term that covers many types of hair-like algae.
