Bio-balls or scrubbies?

scrubbies have a lot more surface area than bio balls but can clog and create a mess very fast. you need to make sure you prefilter the water going into the sump, a good filter sock is essential for this.

proper UV light placement is on the return line

Wouldn't a filter sock be a dangerous thing? if the sock get clogged, then the overflow backs up, which in turn will make the main tank flood? If the scrubbies get too clogged, then the water will build up enough to run over the top of the scrubbies. The water may not be getting filtered as well, but at least I wont have a pond on my floor. Is my thought process correct on this, or am I missing something?

all depends how you set up the filter sock thats why you set it up in the sump in a way that if it clogs, the water will pour of of the sock and directly into your sump, continuing to operate as normal

this is the one i designed and built. you can see that the filter sock sits on a sheet of pegboard. that way if it overflows, water will flow down into the holes, or over the pegboard into the next chamber of the sump. no overflow issues

I see, thank you for clarifying. I will look into putting one in. Thank you for the visual.

Bio-balls, if you want to spend a lot more money for something that has a superior equivalent for a lot less = scrubbies.
