this is the second time this has happened to me in 2 different tanks.
in 2 both tanks i have a uvfilter
one day i herd a funny grinding sound comming from the filter, so i took it all apart ad found that a cl had swam in the intake and into the impeller :-?
causing it to make a grinding noise.
this happened on a smaller uv unit which u cant take the motor assembly apart so hes stuck in there
but when it happened on the bigger uv unit the whole thing just stopped working, but i could take the motor apart to get it out.
so for those of u that have these units and smaller cls beware
