Fish Tank Overflow System

Whats the best filter for my fresh water tank and the differances?

Ok first off I’m new to the hobby and have been trying to do as much research as possible before I start. I have a few questions and ill list them numerically so it’s easy for you guys to reference what you’re answering.

As for the specs. I have a 125 Gal; it will be used for a fresh water fish currently going to house a 5inch arowana and maybe a couple of other fish… So in the future with the arowana there will be a large bio load.

1. What is the difference between Wet/dry, canister systems?

2. What is a sump? The tank I have has an overflow nozzle on it is that for only a sump?

3. What would be the BEST filter for my tank?

4. If a Sump is a type of way to filter out the tank is that the best way to go?

And any other good info you’d like to share please feel free. Like I said, I’m new to the hobby.

Also any good sites you know with deals. And or references would be of help.

Thanks in advance!

Sounds like that tank was set up for saltwater previously.

Sump and wet dry you don’t need or use for a freshwater tank.

Simply and super effective are the canister filters.

Like the other post eheim are impossible to beat but look for one on sale. There so good i would buy my next one site unseen.

But that the biggest problem, owners only buy a new ones when there setting up a new tank. It’s not uncommon to hear people say they’ve had there eheim over 10 years problem and leak free.

Eheim’s is all I use.

Try and find one on sale or online cheap.

There such high quality i would buy one sight unseen once i did the research for size.

The flow rates are less but the determinate to that is the amount of bio media and it’s performance level.

Basically the rates are lower because the bio media capacity is so large and works so well. It’s a compliment to the designers and the lower flow is nice to see wave threw the plants.

I’m sure fluvals are OK too but have never considered owning one.

These “classic eheims” are still in big demand because of how bullet proof and flawless there design is and they are usually priced very well at times.

Plus they come with $40 worth of fast disconnects and $100 in free top of the line media.

The GPH on that is the same for filter half its potential.

Once there full of water they prime themselves for eternity.

there dead quite, super easy to muck with and mine have never come close to leaking.

The only stupid thing i ever did was try and take the top off w/o re-opening the quick connects (suction locked).

A 2nd HOB filter will allow you to customise media and the adjustable flow water fall effect will airate the water for you. plus the media in it you can cycle another tank intantly or help out a friend cycling a tank or create a fully cycled emergency tank instantly by tranferring that filter to a new tank.

I never used just a single filter on a tank in my life and most serious fish keepers don’t either.

Basically the tech behind filters is more in the media of which eheim is already the best.

It’s more but worth every penny IMO

Good luck
