So I'm in the market for a new filter system for my discus tank. I've had nothing but trouble with my AC110, XP3 and my HOT Magnum. The AC110 is too strong and the impeller keeps breaking. my XP3 keeps clogging and burning out the motors and the magnum isn't strong enough to handel the bio load.

Can anyone suggest a filtration systen that isn't too strong, can handle the bio load and not clog every 3 days?

Thanks!

My emperors are pretty good...once the bio wheel gets sludged up it moves slower and the outputs are low enough to give a slower flow effect. I hate AC filters, highly recommended by a lot of folks but I dont like em. Are you looking for other HOB's or a good canister, you have the option of sponge filrtes too which would be great for a discus tank but they lack the mechanical part?.

I've had nothing but bad luck with my AC's. I'm looking for a canister but if there is a HOB that is better I'll go for that.

I'm no pro on canisters I pretty much have only used Renas!

What are you looking to spend is the question.

The Emperors are pretty nice, I find the spray bar for the bio wheel clogs way to easily, but it's super easy to custom make filter inserts, and you can do fairly neat things with them.

The Hagen HOBs are pretty solid. I run a few on the feeder tubs with no issues.

Eheim canisters are bad ass. Expensive as balls, but you may be able to find one on a good sale or used.

As for the problems with the Renas, you need a prefilter on them. I had the same problem with them clogging and grinding, but I built prefilters from some pond filter foam, tubing and chinese food take out containers and I haven't had a spot of trouble with them since. The intake guard is just too wide all sorts of scum that should't get in there does.

What about those HOB's you bought about a year ago Mike? Thread Here Click How are those working out....I was just thinking about it cause you were asking.

I have Aqua Techs. They may wear down after about 10 yrs and die. Thats what happened to one of my original 3. Right now they 2x 20-40's are working great in the 29. Propellers don't break easily.

I own 3 emperors and I haven't had any problems with them. The spray bar is very easy to clean also.

saint I'd like to stay away from the $300 mark.
MC That filter works well but it clogs easily.

This is for a 75 right?

the 72. The 75 has an ac110.

Pretty much anything from Marineland is good IMO....When my AC's (junk) die I am going to get more emperors. I like Renas too but I have had my problems with them. You could just go with Whispers, I have never had any issues with any Whisper I have ever owned.

Picked up an emperor yesterday and trying it out. How do you turn the flow down?

Dang. How could I have forgotten about Whisper. Those things are tanks, definitely not the fanciest thing out there, but at least the old ones are indestructible.

I'm looking at a 400 running right now, and I'm not seeing a way to turn the flow down. I guess you could always point the spray bars inward some.

I have a 400 and tried pointing the spray bar down and it didnt work.
