ADA 120p filter?
 
I'm getting my dream tank (hooray!) and need to decide on a filter.

Choices are:
Eheim 2075
Eheim 2075 x2
Eheim 2078
Eheim 2080

I will be doing an hc carpet and community tank, and want as much flow as possible (without adding an ugly powerhead) to keep things clean on the surface of the substrate.

I've seen pics of people running 2 identical filters on the same tank. For almost the same price i can get two 2075s vs one 2080. What would be better? Does this double the flow or just distribute the flow better? Is it best to run both outlets on the same side or opposing?

Thank you!

I run a 2217 and a 2026 on my 120p and find that flow is perfect for me. I'm glad I had two filters because I broke my adapter on the 2026, while it was down for a week the 2217 handled the tank just fine. Redundancy is key IMO.

Why not just do a sump?

I would recommend getting the 120p with the built in overflow offered by ADA, it is worth the extra $100 and a sump is easy to do.

I appreciate the recommendation but the sump is out - I live in a small condo and I'm concerned about it overflowing and noise. I've heard that the return can be designed in a way where that wont happen.. (and that a container filter can always leak) but I'm just more comfortable with a canister over a sump in my current home.

I like the redundancy factor of 2, thats a good point... when adding two filters can I just combine the gph/lph or do I need to reduce it?

Did some research and conversions:
2026 = 750 lph
2236 = 700 lph
2217 = 1000 lph
2075 = 1250 lph
2078 = 1700 lph
2080 = 1700 lph

Tank is 65G/219L

so a 2217 + 2026 = 1750 lph / 219l tank = 8x hourly flow to volume
one 2078 or 2080 = almost 8x hourly flow
two 2075 = 2500 lph /219l tank = 11.4x hourly flow to volume
two 2217 = 2000 lph /219l tank = 9.13x hourly flow to volume

Based on that.. having two 2075s or 2217s would be my best bet then? And the parts are cheaper on the 2217 so thats a bonus.

The 2217s are workhorses, defenatly a good choice.

If you are going with Eheims, I would recommend running two classic 2217s.

I have a 120P for many years and I have ran the following configurations 2028+2215, 2028+2217, 2075+2217, and finally I ran 2075+ES1200.

I found the classics series to be 'better' than the pro2 and pro3s because of the simplicity of design (no bypasses, no primers) and constant flow in between maintenance (the pro's loses flow much noticeably). If I were to do another one, I would stay with classic style canisters.

Excellent feedback, thank you!

If you use a hang on prefilter(say you want to change the placement some day, you can, and it does not take up planting space in the tank) and have 2 drains for the over flow and the wet/dry,add ball valves to each drain and make one pipe about 1-2" taller than the other......... it's VERY quiet.

See Bean animal's design.

Also minimizes CO2 lost also and adds another 1-2 ppm of O2 over a canister filter system.

All you have is small prefilter scoop in the tank and a small return that you can blast with any pump return of choice. Cleaning? You have a prefilter sponge, which is a 10-15 second pull and squeeze.......and the block sponge below? Once every 3-6 months. Squeeze and return. 10X easier than cleaning a canister filter.

Constant water level in the aquarium, no changes and no degassing changes, evaporation tops, no surface scum.

Here's my 70 Gal example:

I'd have to recommend Fluval G6.

I came from a Pro II (forget what eheim # that is) and the Fluval G series is just so much easier to maintain. It's also very attractive and my G3 is quieter than my Pro II was.

Don't get me wrong, Eheim's are awesome - so if you decided on them, make sure the Eheim's tubing size is correct for the largest ADA lily pipe (assuming you're going to use that?) as I think the pipes only go to 5/8" while some of those Eheim's have 3/4" tubing.

CFS-500 or better yet, get the 700. Best bang for the buck!

My 500 has been running perfect for me for 2 years now.
