today my Rio nano came in the mail first i'll tell you why i bought it then my experience with it,

i chose this skimmer because of the price (20$ Amazon), and the reviews said "when" it works its a great skimmer, to me this means its got some design flaws and needs to be tweeked, no problem for me im very mechanically inclined and it doesn't bother me.

ok before i get into this i just want to let everyone know im going to post a video soon of my mods to make this thing work right

ok so it arrived today and first off the instruction book (or lack there of) was a joke so plan on going to the manufacturer's website and download it because that's the good one , the one they give you is a 2 page joke about safety.

so after i got this thing cleaned and assembled i put it on my tank and started to fill it, it leaked like a pasta strainer, the the motor o-ring was mis shaped and not seated right even after i fixed it it needed Teflon.

ok so the leaked is fixed now i plug this thing in and OMG ive never heard such a racket in my life i was shocked, so i dismantle it again to figure out whats wrong , this one took some time but the insane noise was coming from the white rod that goes through the impeller!!

I never leave customer reviews, but felt compelled to share my experience with this protein skimmer with everyone.

Let me start by saying, I never run skimmers on my tanks. I have had many successful salt water tanks without skimmers. I have had many skimmers from from CPR, Red Sea, to Reef Octopus. I was never successful with "tuning" them in, they always over skimmed and spewed water all over the place, so I decided to go with frequent water changes over skimmers. The only reason I decided to get a skimmer was because, the product I used to cycle my tank highly recommended that I have a skimmer on my tank while using it.

My initial thoughts while looking at other reviews were not good, but I figured what the heck, for less than $30 I could give it a try. Quite inexpensive as skimmers go.

here is what I found:

1) When I received the skimmer, I expected it to have an oil residue according to reviews I had read. I was pleased to find it DID NOT have any sort of residue.

2) The next thing I expected was for the skimmer to leak around the pump. I even purchased some Teflon tape ahead of time to fix it as another review had suggested. I was happy to find that I did not need the tape, and a month later, still do not need it.

3) I did read reviews that said it was hard to tune the skimmer in with the air in-take. I found this to be true, it is either on or off (open or closed). However, that is not the only way to tune this skimmer in. You can adjust the water flow on the water intake tube.

4) I did find there was about a 2 day break in period. I simply closed the air in-take, and let the skimmer run on full power for a couple of days before I played around with tuning it in.

In over 10 yrs in the hobby, this tops the list of horrible skimmers. The overall design is flawed. Fills tank full of bubbles and leaks from the back. I was hoping for an inexpensive skimmer for my nano. I didn't expect much from this skimmer for the price, but this thing is total junk.

The documentation is very poor. Another search suggested that there may be a youtube video.

For anyone reading, the main issue with this unit is the "air plunger". Accordingly, you suppose to be able to adjust the bubbles and the lift pressure by slight rise and lowering of the air plunger.

However, that never seems to work for me. A slight adjustment is too much (results in no water pressure in the lift), another slight adjustment is too little (results in no bubbles). My solution was inspired by someone else--get a cheap plastic air control valve. I got 5 little plastic ones for $1-3. + shipping if applicable total. Once you get to the point where you are inbetween too little or too much, use the air valve to control the amount of air flow so you can get enough pressure and balance with air bubbles.

Other searches for more complete manuals discusses little flap adjustments to help reduce microbubbles. I find the following more effective: adding a little filter material so it catches some before they are released into the tank.

I get better skimmage than air stone version. My skimmage looks brown and milky which is what I expect for decent skimmers.

Design is good for the cost, but very poor instructions.

Warning, this skimmer is a little a little raspy/noisy.
