Depending on which source you listen to or read about, Hagen's BioMax ceramic pieces that are placed as the last stage in the AquaClear HOB series' media baskets will/can either last almost forever or will, eventually, become "clogged" thereby rendering them impossible to harbor new bacterial colonies...does anyone have any more "definitive" feedback on this phenomenon? Will these ceramic pieces get clogged over time, to the point they actually need to be replaced, and if so, how do we know when that is? When we experience wild ammonia spikes or cycle crashes?
I was under the assumption that pieces like the sponge/foam block and BioMax pellets could pretty much keep going until they're literally falling apart...
