This is going to sound really stupid but I just cannot figure it out.
Everybody says that cheato likes to tumble but no matter how hard I try it won't.
I have a fuge that is separate from the skimmer. Part of the water from the tank goes into the first compartment of the fuge and then goes over a baffle into the main part of the fuge which contains a deep sand bed, LR and of course the cheato. Then the water goes directly from the fuge to the return compartment of the sump via a bulkhead low in the fuge but higher than the one in the sump.
I have tried increasing and decreasing the flow to the fuge and have even tried adding a power heat to the bottom of the fuge and I just cannot seem to get it to tumble.
Any ideas?
Thanks for any and all ideas.
