well...as suggested i did a huge water change this mornng...I usually clean my sump once per year in August but it's been 2 Years since I last cleaned my sump and couldn't sleep last night so started to clean my sump at 4am and finished at 9! LOL....all is clean...even fed them MP's and both XB's had 2 big MP's each for the first time in 1 1/2 months so happy to see them at least get a stomach full before starting their dance again!
