You really dont ever need to replace these unless bag breaks. Once you start growin bios, just rinse around in your drain water (10% or so every month), and throw it back on top. I have a fluval on the back of my 60g tank that has been going strong for 8 years now. Replaced these once, foam 2x, and charcoal 3x total. Rest of the time I just rinse. Bearings are getting loud so I may need a new one soon. Kind of sick of my fish though - 13 years with 2 big jack dempseys, a parrotfish, and 5 silver dollars has got old (will they ever die?). Ready to go back to african chiclids, or try discus...

Bio-media surface area and approximate price chart: https://i.imgur.com/hcu1Yhb.jpg

Missing from this chart is Seachem Matrix which is highly porous, crushed volcanic rock that's comparable to pot scrubbies in surface area and pretty affordable too.

For ANY bio-media you should avoid heavy-handed cleaning as you will damage the colonies of beneficial bacteria. Using water from your tank, slightly agitate or squeeze the media to remove large gunk and then place it back in the filter. If you have good mechanical filtration practices you can go months or years without needing to clean the bio-media.

Is this any different than the Marineland for $3.49?

You've only changed your carbon 3x in 8 years!?! 😂

Might as well replace them with these for more surface area since they're just providing bio filtration at this point.

Carbon is only good for so long until the pores clog up and do nothing to purify the water.

I know - it doesnt make sense. I do have a couple of little catfish too, but no algae eaters. I just suck out a 5g bucket every 6-8 weeks, wipe the sides, and rinse the 3 innerds of the filter in the bucket (then pour that brown shit into my patio plants). These bio ceramics do not break down...

After it houses bacteria, RINSE ONLY using tank water! Do not use tap water (city water contains ammonium chloride). Chloride kills beneficial bacteria. No beneficial bacteria = higher ammonia (toxic to fish).

Yeah, this sale price can also be found on chewy.com, but it's never over $7 normally
