cheato dying off

danlu_gt · 07/19/2007, 02:07 AM

Starting about 2 weeks ago my cheato are turning pale and dying off. Usually I have to remove 60% every 10 days or so. Everything else in my tank looks fine. Any know causes? Chemical/trace elements imbalance?

I have chaetomorpha that is not doing well. I haven't tried iron supplements but here's a suggestion from Randy Holmes-Farley to use iron:

"I have also heard from many hobbyists whose macroalgae (such as species of Caulerpa) have grown pale over time and were not growing well. On iron addition, the macroalgae greened up considerably, were much more attractive in the eyes of the hobbyists involved, and were growing substantially faster. I have also personally never had my Caulerpa racemosa undergo sexual reproduction despite years of vigorous growth, but that may or may not have anything to do with the iron additions (see discussion below).
