Maybe you should add "up to 30 gallon only" to the title.
Not a good deal to me.

More than 50% off and sold by Amazon is not good? Ok then.

I can't say enough good things about canister filters. Looking at this for my son's 10 gallon tank. Bit of overkill, but much better than the installed filter.

Don't get defensive. I think he was just saying the pump is too small to do him any good. My aquarium is 65 gallons, so same here. Just put max 30 gallons in the title, that will take care of it.

It's always better to overfilter than underfilter I've found. You can't have too much beneficial bacterial. This however will take up a lot of ground space but can be used later when you upgrade sizes or increase fish load.

It depends on the fish. I usually go for 2 to 3 times the amount required with 2 to 3 different filters. No sponges inside. Just bags of media and carbon. Sponges on each of the intakes which slows down flow but gives more bacteria and less junk in my filters since i have sand tanks. It also protects the fry from being sucked up.

I only cleaned out each filter twice a year and never all at same time.

I gave up on activated carbon a long time ago. It was also a pain to take in and out every time you want to medicate something.

If I'm not mistaken, it can also suck up some of the nutrients that a planted tank would benefit from, so I usually just alternate foam blocks and ceramic bio media. Everybody's happy.

I had no idea it took away nutrition. Never had a planted tank. But it's still good to know.

Pretty agreeable, the more available surfaces for the bacteria bed to colonize the better over all.

Generally the beneficial bacteria colony should grow and shrink based on the food supply available to it. That said, some media's can house a lot more bacteria and make the filter more efficient. 2 of these on a 65 would likely be enough to handle it, especially if you changed from ceramic rings (assuming that's what this comes with) to something like Seachem Matrix that has a higher overall surface area for the bacteria to live.

Give the Purigen product from Seachem a whirl if you ever have clarity issues etc. It's pretty good at polishing water and helping to remove things that would cause nitrate spikes, supposedly without scavenging for the fertilizers and such that plants love.

Rechargable too, most people could get by great with a pair of the small pouches. One to run in their aquarium and one on deck ready to swap out when the other needs recharged. Or just wait a few days for the process.
