I posted recently about the low backwash rates that my Filox filter had been supplied with (3.5GPM). Well my 1.5CuFt 10x54 calcite tank is in the same boat. I have replaced the DLFC with a 6GPM, and am getting absolutely no media lift in backwash. Zero. I can watch it by shining a light. I tried a 7GPM button, and the same.
I am thinking that the years of poor backwash rates has caused it to become packed and turn into a solid brick. I have added some media over the years, about .5CF every 2 - 3 years.
It still seems to be regulating my PH well as per my testing, but it is used as my primary sediment filter and I have a lot of sediment so backwashing is important.
How should I approach this? Can the media be unpacked? Do I need to dump it out and reload? Any other ideas?
