Hey everyone! I am trying to figure out why my dang chaeto isn't growing! I have a it growth with the cheap regular household incandescent bulb on my 60 frag tank and on the 180 its has a zetlight E200 that is designed to grow the stuff! I have nitrates in the water and phosphates so I am not sure why it hasn't grown at all.....unless it is growing at a snails pass and I don't notice it growing. I only ask since my last setup grew chaeto like a weed and I was taking softball size chunks out every week. Let me know what you think and what you think I should try.
