Thank you so much, the subbwassertang was pearling in the tank. I think it liked the fact it was so close to the light and the colder water since my cat unplugged the heater and the tank was a bit chilly, lol. I really cannot wait to get some planted tanks up and going again, you should have seen my 75-it was overstocked with plants. Lots of CO2 and EI ferts. <SIGH> Can't wait to get those tanks up and running.
