My Fx5 is 1 months old and it is starting to push a lot of micro fine bubbles out. I Google and read a lot of threads about this problem and most of people think the reason is because it clogged inside. So I cleaned my FX5 very well yesterday morning and make sure nothing can clog but for the entire day yesterday until now (more than 24 hours) it is still pushing a lot of those fine bubbles out. ALSO I did check all the hoses, tight the top down very well and no leaks anywhere. So for sure there is no way air can go in the filter. I'm thinking it is because things INSIDE it. The impeller still work very quiet not noisy at all. ANYONE KNOW HOW TO FIX IT. PLEASE HELP !!!!!!
