Canister = sump?

[xDestro]

Hooked up my fx4 on my 75 today and noticed my water level dropped quiet a bit. So if I were to have a fx4 on like a 20 gallon would that basically be a sump?


On another topic can anyone recommend me a canister filter for a 20 gallon long?
Stock will he f8 puffer and bumblebee gobies.

^ for a 20L maybe use some kind of HOB system would make more sense, since cleaning it would be much easier...

The art of the sump is easy maintenance. More than mass water volume.

Not a big fan of hob filters but what are a couple good ones/ brands? I like overkill filtration at least 3-4 times water volume

I hear people keep recommending the AC110? Although that will be way overkill on a 20G i think...

Or course, these are different things used and chosen for different reasons.

According to Fluval, the FX4 has a filtration volume of 3.7 gallons with space for 1 gallon of media. A sump for a 75 would perhaps run around 15-20 gallons in volume and carry has much more space for media.

So, if you are strictly looking at volume, it's more like:

Canister = 1/4 sump

Cant go wrong with overkill filtration

Yea that's what I figured it would be about a 1-4 ratio I just figured a big canister filter would act as a sump on smaller tanks allowing larger water vplume fir easier maintained parameters or larger/more stock.

ac70 and a sponge would be plenty for a 20

I have two Aqueon QuietFlow 20 HOB filters on my son's 10 gallon aquarium. The same would work on your 20 long, and you could probably add a third if you wanted to. On has the sponge it came with for mechanical filtration and the other I filled with ceramic rings for bio.





Another option could be a SunSun 302B canister filter. I think they run about $60 on Amazon. However, as others have mentioned, they are not the easiest to clean.
