I have a question for everyone who uses egg crate for frag racks. Is there any chance it (the white plastic material) is leaching something in to the water? I have a 90 g with no algea to speak of anywhere in the tank. I mean none. None in the rock work, none in the substrate, none on the tank walls. But for some reason I always have a layer of green hair algae on my frag racks in the tank. The frag discs end up with algae on them from the rack. As soon as I move the frag down to the rock, the algae goes away. I originally thought maybe the racks prevented proper water movemnt near the frags so I made sure a power head pointed at the racks. Still no change. The snails, crabs and fish all have equal access to all areas of the tank including the racks so I do not think this is the issue. Has anyone else noticed this? Is there some other mateial I can use for frag racks? Thanks for any feedback. Bruce

I am up for anything. I have already caught him and have him in a breeder net in the main tank. If you have any sort of coral, or fish, I would be happy. I am always looking for a frag. Bruce
