I personally run 100lb of LR
in my 60g tank and everything works well. The only thing people need to remember about running this type of setting is to have some kind of setup to keep water flow under all the LR
. I found that with PVC
pipe drilled with many holes and place in the sand and have LR
sit on top of them works very well. 1)is that you lift up the LR
and the water can flow under the sand that will not create "dead spot" 2) is that connect those PVC
to a small power head and now you have the entire sand bed water flow issue take cared of.
