External filter for 6g

Hello,

I have a heavily planted Marineland Eclipse 6g tank. I removed the original filter on top because it takes up the back half of the upper portion of the tank. I retrofitted 20 watts of lighting and also added diy c02. Now all I need is a non-hanging-on-the-side-of-the-tank filter. I'd prefer an external cannister filter that I can put in the cabinet below the tank. What would you all recommend?

Thanks,

Phil

It might be a bit much, but a ZooMed Turtle 501 would do it.

a heavily planted 6g with 20w light and DIY Co2 sounds like a wonderful candidate for filterless operation.

I've never attempted something like this. What are the pros and cons?

Thanks,

Phil

Your options for external filters on a 6g tank are limited pretty much to the above Zoo Med 501 and maybe one other one.

Your options for *useful* internal filters are limited because you are pressed for space in the 6g.

If you don't have a lot of fish in the tank then you probably only need the occasional water change.

Running filterless in your situation is done by simply not putting a filter on the tank.

The pros of going filterless would be: cheaper, less clutter, dead silent, no filter cleanings.

The cons would be: lack of circulation, if you have a lot of fish in the tank you may need the extra biological filtration (depending on how much you fertilize the tank).

The tanks is relatively small at 6 gallons, heavily planted, DIY Co2ed and not highly-lit. If you wanted circulation you could just add an inexpensive pump like the Via Aqua 40 gph (VA-40?) or 80 gph (VA-80) or the 66 gph (VA-60) . Very tiny, very quiet, very low profile, adjustable flow.

I have quite a few fish, so I'll try the Zoo Med 501. Thanks for all the help!

I'm starting up a planted 5g cherry shrimp only tank, is it safe to go filterless on this tank assuming I do 50% WC every week?

Yes.

Technically, no planted tank is filterless, as the plants act as chemical filters.

If you happen to be using Aquasoil watch the Ammonia readings for the first few weeks, as that substrate releases some. If you aren't using Aquasoil, just do the weekly water changes.

I'd put mulm and a LITE dusting of peat on the bottom glass while setting the tank up, if the stuff is available to you. If not, don't sweat it.

Thanks random.. good point. I put down the peat moss and flourite and filled the tank last night. The Hagen is spitting out bubbles every 6 seconds or so for starters. Without any circulation will the co2 get to the plants as needed?

I have a filterless 2.5 gallon tank. It can DEFINITELY be done. And very few water changes. Check out my signature. It's a low-tech soil-based tank. Definitely the healthiest, most stable tank I've ever owned. And also the least maintenance. And, turns out to be the heaviest stocked, 3 guppies, 6 adult shrimp, dozens of snails and baby shrimp. I've seen plenty of other folks with the same experience as me.

Plants are unbelievable filters. No one gives them enough credit. I bet many of the healthy tanks in this forum could go filterless and do just fine, if not better. There's a lot of "common knowledge" on this forum that works; and there's a lot of "uncommon knowledge" that also works, sometimes even better. Just takes a willingness to experiment, a leap of faith, and some patience.

Good luck!

Cool, thanks for the link littleguy. That answered a few questions I had. I was especially concerned about not having a heater for the cherry shrimp, my house stays at 70.
