These tube worms are killing my zoos. Very slowly but surely. They are spreading. They retract into their tubes very rapidly if disturbed. They fluoresce a light green under the 14k. Was wondering if anybody knows what it is and how to go about removing them. Thanx.
I also noticed that with more surface area with the hob filter on the back with an open top along with more surface agitation will help with the fans cooling efficiency
I use a twelve inch on a 24g and freeze RO/DI into blocks and put them in my ATO. And my ATO fills the tank very slowly. With an ambient air temp of 90 I can keep the tank at 81. But keep in mind that the fan will cool much better without any humidity in the air.
