Mackayman Posted May 2, 2012 Report Share Posted May 2, 2012 Just looking for opinions on how long a Bio Ball lasts b4 the plastic breaks down. I've heard many different theorys; Replace a third of them every year Replace all of them every 3-4 years, etc My own thought is that there good for at least 5 years What are your thoughts, experiences :confused: Thanks Brendan Link to comment Share on other sites More sharing options...

xysti53 Posted May 5, 2012 Report Share Posted May 5, 2012 Depend on the plastic they are mad of and the amount of light they get. I have some black and grey Bio Cubes that are over thirty years old and are still as good as the day they went into the sump. Yet I also have some blue bio balls that are less than 10 years old and are showing signs of wear already. Still think I will get at least another 10 - 15 years out of them.
