Hey All, I have been battling a problem with my girls in my RDWC system. After a great deal of frustration I thought it was finally resloved. http://forum.grasscity.com/sick-plants-problems/1245812-help-plants-dying-when-moved-flower.html They are looking much better and showing new growth. I went to check on them this morning and found the recirc pump was not moving any water. Checking the pump I found the intake filter completely plugged with a tanslucent slime. I have never seen anything like this before. I have had algea in the past but it has been brown or grey. I looked closely at the roots yesterday and they looked fine. I took a quick look at them this morning and don't see any change. I have no sign of bad stuff in my control tank either. Can anyone identifiy the crud in the pics? I am going to replace the filter and dose the system with H2O2 again. Any other suggestions? Thanks!! FJ.
