4g (19L) filtration advice.

Hiya peeps.

Tossing up whether I should go with 2 AC20ís or a single larger filter, ie AC50/70. I want to put my heater in the filter (with guard) to increase tank space and aesthetics.

Iíve pretty much decided on Aquaclear due to many reviews and comments about how quiet and reliable they are, as well as ability to customise media etc.

Cost isnít a huge concern. Filtration and flow control are main concerns. I donít want too much flow and I donít want too much weight on the tank. I like the idea of rotating filter cleans and half of one filter dedicated to the heater. So Iím leaning toward the 2 AC20ís.

Will be low tech planted with shrimp and tetra. Small desk tank so really want a quiet low maintenance setup. Any comments are appreciated thanks!

One 20 would be plenty for that.

Yes Iím sure it would be, but with the heater in the filter it limits media, hence either getting bigger or a second filter.

I suppose another way to word it is, would an AC70 be too big for this tank?

Sorry for stacking my own posts, I dont know how to delete other posts or this entire thread.

I think I am going to get an ac30, and using a heater guard, place the heater in the corner of the media area.

I think placing a heater in the media area of an AC filter is a bad idea. Place the heater low in the rear of the tank, just above the substrate - with plants and decor you'd never know it was there. I have a 12-14" 500w titanium heater in my 60g and you can't see it from view angles.

Tank On, Mike-
60g Marineland Community, Finnex Planted+ 24/7, Silica (pool filter) sand.
10g, 29g, & 37g fry grow out tanks, 110g stock tank.


What came first, the chicken or the egg. It was the egg, but not the egg of a chicken.

I have a 200 watt heater that is about as long as my 10g tank is wide. I have the heater about 1 inch above the substrate in the back, and you would never know it was there because it's completely obscured by plant mass.

Cool looking tank. I have a few 4g nanos, filtered in a few different ways.
I’d go with the advice from AbbeysDad, personally. If you adjust the flow down on the AC30, you may still be pushing your fauna around. A single sponge filter is enough, really.
Seems like you want the inside of the tank clear of hardware. Perhaps consider an in-line heater and small canister? Zoo Med makes a filter that I considered. I ended up making my own instead. I have a Hydor ETH300 on my 40b - love it. Smaller versions exist.

I can only grow plants when they're completely under water. Everything else is doomed.

Your reasoning? Not doubting anyone knowledge here just getting back into the hobby after years away and Iíve seen it done plenty of times without issue. The tank is small enough that I wouldnít expect any cold spots. If all I need is a basic thick sponge filter, then I can create plenty of space in an AC30 for the heater. I donít see any conís?

Thanks, itís a Fluval Chi, but Iíve gotten rid of the horrendous filter/light box haha. Iíve got a few different lights to try out on this and may end up making a custom lid. But it sure is a nice little tank for my desk space!

I would go for a canister, however maintaining them can just be a pain after a while. I definitely do want the tank clean and clear of as much hardware as possible. As above, if I donít need much media then I may mod the AC30!

If you want low maintenance, why not just do shrimp only? They prefer cooler temperatures anyways, so I doubt you'd even need a heater unless your room gets really cold during winter months. The light will add a little heat itself, especially on nano tanks. You may even be able to get by with placing a heat mat under the tank to add a little warmth during cold months. There's also the whole predatory thing with tetras and baby shrimp, if that matters any. Not many fish will pass up an opportunity to feast on some little soft shrimps, except otos.

I could do shrimp only.
I honestly didnít think little neon tetras or the likes would eat shrimp so yeah might have to haha. Thanks for that input!

I wouldnít do an under tank heat mat on this tank, as the base is plastic. All my lights are LED so I wouldnít imagine theyíd put too much heat into it.
