I haven't posted in awhile but lately I'm having an issue.....
I have an external overflow (cpr) and I'm having to clean it every single day because if I don't the siphon will slow and my main tank level will begin to rise. When I go to clean it, the prefilter sponge and the floss that I keep in there is very, very slimy. Once cleaned, it works perfectly until the slime returns.
I also run an emperor hang on filter on my sump and run carbon......I have had to replace the cartridges every week due to slime bulding up and water not able to get through.
The only change in my tank of late is that I mysteriously lost a shrimp (could be my sixline, not for sure).
After this event and finding the slime, I thought maybe that could be it.....I have done three 20% PWC
's over the last week, which seemed to help, but then the slime comes right back.
Oh, almost forgot......I am going to check water params today, but last time I checked them (last week) everything was perfect.
