What type of filter?

I'm going to buy everything for my NPT tomorrow. What type of filter should I use if I am planning on having Duckweed in my tank? I like the look of floating plants, but I want to make sure I have the appropriate filter for such plants.

Sponge?

Over hundreds of bettas die in their small, dirty cups each day. Only you can help them live. Research and then save them, today!

Are you asking?

I know nothing about filters. This is all new to me. None of my tanks have filters.

Ah yeah, I'd go with sponge filters as well. You can get them off ebay/amazon/petstore sites. Basically they're air driven and they're at the bottom of the tank anchored in the substrate and they suck in debris while letting bubbles out the top so there's still some circulation but it's nothing like what a HOB would do to your floaters or anything. So yeah, definitely sponge filters. I'd get two to make up twice your needed filtration so if it's a 20 gallon tank, then use two 20 gallon rated sponge filters. That gives you 40 and then when you need to change out the sponge you don't have to lose a whole colony of BB when you do change it. But for the most part you just take out the sponge part and give it a swish and squeeze in old tank water and it's good to go!

Oh no, I'm not asking. Since you help a lot of members, I thought you knew. ^.^

Sponge filters are just sponges with a tube like thing and air tubing. The air pushes water into the sponge and therefore; filtrates it. It seems to be best for BB, a lot of media and whatnot. It just bubbles up to the surface; it has no intake. Here is mine.

That's not exactly how a sponge filter works. The air does not push anything. The rising air bubbles create a vacuum behind them, which pulls water up into the void left behind. The vacuum created by the bubbles in the center of the sponge (and in the tube like thing) is what draws the water into the sponge, filtering it.

Don't mean to nitpick, but words have meanings and there is right and wrong with regards to physics.

It is really up to you. HOB filters have an intake lower than the duckweed, canister filters you can adjust.

Believe me, nothing bothers duckweed.

Duckweed actually hates one of my HOB's and won't grow in one tank miraculously and in my big 33 it only grows where the water sprite is floating and doesn't populate that much thankfully lol

Duckweed dies in my tanks because of the current and surface disruption.
