Which would you guys recommend for a 55g. Im having trouble deciding on 2 filters for it. Ive read good things about emperor and AC both. I know its probably my own opinion or choice, but I was just wanting to hear your thoughts on it. By the way someone tryed selling me a Tetratec PF500 today, and Ive real to many complaints on here, so I said no way. Thanks.

I personally like the Emperor 400. Great media storage space available and is very quiet for a filter.

I like both of them. The AC is economical and gets the job done, but the Emperors are easier to start when they've been turned off. We have quite a few power outages in my part of the country. Sometimes for a moment, and sometimes for hours, and the Emperors always start right up. I usually have to prime the AC's. I do believe the AC's are quieter than the Emperors though. And I've never had to replace the impellar on the AC's, but I have on all 3 of my Emperors at one point or another. They still worked fine with the old impellars, they just got noisy.

So what I'm saying is "If money is a problem, get the AC, if it's not, buy an Emperor". Both are good.:ok:

And oh yeah, this should be in the equipment forum.

both are great filters, i thing the Emp 400 will handle a larger load then the ac 500 because of abilit to add more chemical/bio/mechanical media to the trays, and i think the bio wheels do a great job of both oxigenation and nitrite/nitrate removal, but i could be wrong on the last part.

just my 2 cents

I think you'll find the Emperors are superior. Their bio-wheel allows them to be mote efficient than the AC's, and the media container makes them very adaptable.

I too like both... I use more ACs though due to the economy with the sponges they have... but I do use cut up AC sponges in my emp as well :)

Thanks for the opinions. What all do you guys fill the trays with?

And also would you guys still recommend using air pumps/bars/stones, if I had 2 filters running.

I almost always use air stones in my tanks to increase water circulation as well as oxygen transfer... probably isn't necessary, but its personal preference. Also, IMO, unless you have a big sump or something 2 filters on a 55 is minimum. I'm getting amother AC300 to throw on my 55 so that I have an extra seeded filter in case something bad happens or if I need to set up another tank, and to better handle the crazy bioload a tank full of mbuna generates... Can never have too much filtration! Now I'll have around 1100 gph on my 55!! :D :dance:

I cut 10 micron pad material ... to the shape of the inside of tray and put it after the regular filter tray.... kinda like a final polisher... it gets brown every week so it must be catching the last little bits before they go back in to the tank... my water is crystal clear, though!

I do the same, but I also fill the containers with crushed coral or PolyFilter. Fabric store batting on the upstream side with a rubber band for a completely DIY alternative that's cheap!

I'd say to go with both, I like to run back up filters. Alternate cleaning the media between the two. If you went with a Emperor 400, I would go with a AC300 for a back up. For a AC500, backup of a Penguin 330 or something.

They both have their pros and cons, which are probably in 100 threads to sift through.

Thanks for the help guys, I think im gonna go with both of them 1 AC500 and an Emperor 400. With black moon sand and some limestone piles. Should look nice, hopefully I wont regret the black sand. Anyone used it?

I use Tahitian Moon black sand in my 90-gallon, and absolutely love it (the fish love it, too). I find it easy to clean, and it does a good job of hiding the debris on the bottom between cleanings :). I have a few less-than-professional pictures in my gallery, if you want to get an idea of what it will look like:

Nice looking tank, how many pounds of the black sand did you use for the 55g.
