Done with Eheim - sunsun review

  • We are currently upgrading MFK. thanks! -neo
Im not trying to come off as racist or bigoted here. Poorly translated Chinese products are one of my favorite sources of amusement. I dunno why. It gets me every time. All the money and time invested in these products and they never run them past someone who uses English as a first language. Gotta love it.

You can use it for the ocean too.

You absolutely cannot beat chinese packaging. My personal favorite was the back of the red chopsticks packages that said "enjoy your nice chinese food with wonderful chopsticks" but that has undoubtedly been replaced with "100% filter".

Side Note: I love the artistic touch in the photo with the alternating colored media boxes. Beautiful.
 
Nice!

Tips: 1) soak green hoses in near boiling water for about a minute and it'll slip on super easy and stays on super tight once its cooled down. Also, insert the hoses onto the tubings until it completely bottoms out. 2) Save a ton of sweat, from priming, by filling the entire canister with water before reassembling/starting unit
 
Thanks for the tip. I always fill my canisters. Ive got a pile of hose clamps on deck. Ill see how flimsy the returns are. Don't know if itll crush the pipes when I torque em down.

And im so glad its 100% filter. I was expecting 80% at best.

good purchase I use to use one of these back on my smaller tanks and the thing was a beast. when I set up another turtle tank I will use it again. the uv one is not needed as its small and flowrate is to high. not worth it imo. but I am a sunsun fan for sure. I love touching the perfection lol

"Dirtiness entrance power"

Informative parts list

I dont know if thats too small to read or not.

Enough making fun of the literature

I paid an extra $5 (per canister) for a "kit" which included a sponge and a pack of poly pads (mech filtration) ill actually use them to make a template.

It also came with fake biomax, bioballs, and carbon. I have no use for carbon ever.

The stuff came in nice media bags which fit the canister well - except no bag for the bioballs. Not sure why you want bioballs for a canister but they'll fill the gap for a while until I buy new media.

The media bags appear to be nylon, have synthetic zipper teath but metal zipper pulls. We'll see how they rust.

The biomax looks really bad. There are almost no visible pores. It reminds me of fluval prefilter things. The hexoganal shaped ceramic rings that serve no real purpose.

I was actually impressed with the packaging.

It actually is pretty heavy. I was surprised by its size

Next to the baby ehiem, and a fluval 406 which cost as much as a metric ton of sunsuns. .. ok actually as much as 4.

Nice grouned plug. Maybe 16g.

Spacious interior. Best in it's class.

Nice collapsible handles on the trays.

The overall build quality is decent. The body of the canister is thick. Approx 1/8 inch. It feels similar to the body of the fluval or eheim to be honest. Its that same type of plastic. Forgive me for not knowing my polymers but it feels like lego plastic. There I said it. Legos. It feels like Legos.

The trays and minor stuff are made of lesser plastic to save money. They feel brittle. Very much the antithesis of lego plastic.

The goods.

The fake aquastop valve is of decent quality. Not lego plastic, its more akin to megablocks plastic. I kid you not. It features nice silicone orings. Im not sure if i trust it as far as I can throw it yet. A schedule40 union and ballvalves inline in the hose may be a possibility to spare having to operate it a lot.

The hoses are awesome. A tad bigger than 5/8 standard but they fit on a 5/8 barb snug enough to get by with a hose clamp. Mine are very flexible. They are a little softer than my eheim hoses. I had no troubles installing them, they are of a soft durometer and slid right on with a little water. Actually saliva. But you know

Now for some dislikes.

The pipes are flimsy. So bad. The spraybar is half a dozen tiny fittings which are loosely associated as a single unit. There are some of these fittings that are exposed out of or above the tank. To combat this I slid a piece of hose over the return "u" so if this decides to leak the hose will direct any water down into the tank. This thing is basically made from old pen caps smashed together by a bored school boy, I disapprove.

The siphon or "dirtiness entrance power" has a stupid telescopic feature which is pointless since they give you a pile of tubes to endlessly connect. I slid hose over the connection since it doesn't appear to be water tight, and I dont eant it to loose prime when I do large water changes with the canister running

The motorhead seems OK. It feels heavy. The oring is beefy and actually comes pre-lubricared for your filtration pleasure. Im not brave enough to open the impeller cover. I'll probably break something. So this review falls a little short. What's under the hood? I dunno. Def not a hemi.

Based on real world tests I read the hw302 rated at 265gph runs about 150-180 gph filled with media. Not bad.

There are lots of splines or ridges on the interior of the cover to aid in strength. It looks like ABS plastic. It's got that "marbled" look. You know what im talking about.

The big hole is for the prime button. This is an ingenious design. This "well" is the highest point in the filter, air will rise and collect here. Depressing that huge ugly blue button makes the hole flush with the motor head and forces the bubbles to travel up the impeller and out the return. Pretty neat.

Im going to set one up on my tank tonight. The other I will in a day or two. I don't want to shock my fish with too much glorious communism.

Thanks for tuning in.

More updates to come
