Often they’re in the wrong place. The truth is, fish waste sinks. That’s why a biOrb filter is at the bottom of the tank. It works where there is most to filter.
biOrbs are made from acrylic, not glass. Here’s why...
Acrylic is 10 times stronger than glass. In fact acrylic just over one inch thick (32mm), is actually bullet resistant.
It's also noticeably clearer. Acrylic has a transparency rate of 93% making it the clearest material known. Glass only allows 70% of light to pass through and thick glass always has a green tint.
