Red Sea Reefer RSK Protein Skimmers - Efficient - Quiet - Ergonomic
Red Sea Reefer Skimmers are powered by Sicce`s PSK Skimmer Pumps, a pump well known among hobbyists around the world for their efficient output.
The silent operation of the Reef Skimmers are attributed to the large air intake silencer, and the vibration dampening feet and connections.
The diffusion chamber of the Reefer Skimmers disperses microbubbles produced by the PSK skimmer pump evenly through the conical ergonomic body, while maintaining air and water flow.
Features:
FoamView window for foam regulation
Neck cleaner integration
Drain port connection with 3 foot draining hose
Graduated collection cup to monitor skimmate production
Highly effective air silencer
High volume reaction chamber
Sicce PSK Skimmer pump
Two positioning options for the skimmer pump
Precise gate valve for skimming control
Vibration reducing footing

According to the water box website, the 70.2's sump has a skimmer section that is 7.08€ x 17.2€ This skimmer is 9.1" x 8.3" or 9.8" x 7.1" Unfortunately, it probably won't fit.

This is a nice skimmer extremely well built it is a beast. The neck cleaner is very nice and the "viewing" section of cup is very cool and works perfectly. Sicce pump has plenty of power and produces nice bubbles for nice dark smelly skimmate.
Now for the cons......the skimmer cup is very very difficult to remove..you have to rely on the neck cleaner and the extra large drain hose for daily maintenance. You would not want to struggle with removing the cup on daily basis. I have had problems with intermittent noise from the skimmer it gets really loud for periods of time at random. i contacted redsea they were extremely helpful but were unable to resolve the problem. They even sent me a new pump and well it still makes the noise off and on. I can deal with it and I am not sure if its a problem with every RSK 300 but it is definitely a issue with mine.
Its definitely not set and forget I use the recommended water level and have gone up to 8 inches down to 6 and I still find myself making daily adjustments. It also took nearly 3 weeks to break in ....
Would I buy this skmmer again?? I would have to say NO but issue is not bad enough for me to purchase a different skimmer.Hide
I love the built in wiper for cleaning the neck. I wish they would offer a add on motor to automatically turn the wiper and clean the neck. For the price it's a good deal.
It's hard to keep tuned more then a couple of days.

It's nice looking, Drain line is nice

Hard to keep producing skimmate, red sea instructions and support advise don't help.

I really wanted to like this skimmer more. The water level marking on mine was way off. It needed to be at least 2 more inches out of the water to get anything. I am constantly tinkering with the bubbles. It will be good for a couple days then either overflow or not do anything. I bought the Skimmer safety switch and it's saved me a few times.
I will be shopping for a replacement after a year of wasting time on it.
I contacted Red Sea to see if I was doing something wrong and they basically read the manual to me with a nice time if voice. It wasn't helpful to solve the inconstancy issues.
Nice feaures but difficult to keep it operating correctly

PROS
easy to install, easy to use, and not too hard to take out and maintain. I love the drain hose as the best feature. It is quiet and I can barely hear it inside the cabinet. I cannot hear the motor, only the bubbles. Once you get used to taking it out and apart and cleaning, it isn't bad at all.
CONS
cannot keep the skimmate overflow consistent. I have wild swings in where the correct position of the gate valve needs to be. It will work correctly for a few days, and then the foam will drop very low, or it will go into massive overflow. I do not trust that I could go out of town for a business trip and feel confident that it will maintain itself consistently.
REVIEW
All in all, the design, ease of installation, and other features make it easy to start up. I really like the drain hose that allows me to drain the skimmate without having to take anything apart. I don't believe any other skimmer on the market has the drain hose.

This skimmer operated well for the first 6-8 months. I could maintain skimmate such that I needed to empty about every 3 days, like clockwork without having to adjust the gate valve - set it and forget it. Now, getting the right adjustment with the gate valve is inconsistent and I have wild swings from underskimming to overskimming. At first, I had a very clear mark on where the gate valve should be which would produce skimmate on a consistent level. Now, I cannot find a consistent spot. Sometimes I have to open the gate valve nearly completely open to get foam to overflow. Sometimes I can get the right adjustment and it will work for a few days, and then the foam level drops and I have to continue to open the valve bit by bit until I can get foam back up. Sometimes I have to have it nearly all the way open and it will operate correctly for a day, and then it begins to flood over and dump back into the sump. Sometimes I can have it operating correctly for 3-4 days with gate valve halfway open, and then it begins to overflow and fill the cup in a matter of minutes. I cannot find and keep an adjustment that makes it work consistently. I am constantly having to tweak the gate valve by tiny increments up or down. Its either working correctly, I can't get foam to rise, or it is in massive overflow causing skimmate to flow back into the sump. I have to monitor it several times per day. There is no 'sweet spot' that I can find that will consistently produce skimmate at the right level, day in and day out. It worked fine for over 6 months, and now I have to monitor it daily.Hide
CONS
Too big, doesn’t skim correctly, too hard to take apart
REVIEW
Pretty easy to install, very big skimmer. Needs to be lifted out of the water a little in order to work. Very hard finding the perfect balance and flow for skimmer to work properly. Defiantly not the easiest to take apart and clean. For the price I would not purchase this again.
I bought this a couple of months ago and finally set it up a few days ago. Although I haven't seen it work for long I will say it was easy to set up and it is ultra-quiet.
