Fluval Biomax 500 g

Had this in my filter for a little while and it seems good. It has a slight brownish colour after a while, so definitely some nice biofilm. I appreciate that it doesn't clog and if you pre-rinse it out of the box it doesn't seem to cloud the tank. Impossible to say really how this compares to other bio-media on the market.

Good fits well in my filter

Hi there all.These will be amazing, so don't let the 4 stars put you off.The reason for the 4 stars are for the fact that my Fluval 206 came with 120g Biomax and is only about 1/3 full on the tray.This Biomax by fluval appears to be a different design.The pieces are approx 1/3 to 1/2 bigger than the pieces of Biomax supplied with the filter.That being said, i still got an additional 150g installed into the tray, (taking me to 270g), where as i would have got maybe 200g with pieces of the same size.It will do the job, but just be weary if you want it to match existing media that comes with Fluval canister filters.As a bonus, my pack received 515g once out the box.

Plenty here. I get a few uses from each pack, making it great value for money.

Okay

I have this media for some time now. What I can say about it, it does indeed absorb water very well. Sintered glass is a really good idea for bio media.I have this mixed with hydroponic pebbles in my SUNSUN 704B Filter. I have three massive trays filled with this and the clay pebbles and the fourth tray as mechanical.I have no issues with bacteria sorting out my nitrogen cycle during any stage of maintenance or water changes. The one bit of advice I would like to give about this product or any other static biomedia is to make sure you're mechanical filtration is hit first coming into your pump ((Course / Medium / Fine) => and then the biomedia. You certainly do not want this getting hit with debris and block it up.If this happens you can always soak the media in H202! It will clean and clear up the pores.The last thing I have to say about this product, it that is is cheap for what it is!!! It's proper sintered glass, with a high density of pores to absorb water. Other media out there that does the exact same thing can be very expensive.

Bough these as I needed to add some to a few external filters I bought. Not exactly sure what they do, but the seem to work fine. The water is clear and the fish are still alive. What I can say is that the box was a lot bigger than I thought for the price and I would highly recommend this product.

Can't really go wrong with this stuff. It's top quality and shines above some of the other cheaper products out there. Very little dust in the bag, so a quick rinse before use is all you need. It is more expensive than the rest, but then it does appear to be better.
