I just installed the BH-1000. First thing that happened was the pump was not working.. It would just heat up but nothing happened, so i took the pump apart and put it back together and bam! started working.

The pump is quiet which I like, and it does produce a lot of microbubbles but I just put the SQUARE black sponge on top of the return nozzle instead of under it and it basically stopped all my microbubbles.

It hasn't produced any skimmate yet, but has a decent head of foam.

Has been up and running for months and still has serious microbubble problems that have to stopped with a sponge that has turned into a nitrate farm and it doesn't even work very well.

I don't have a sump on my 55g system so the hang-on-back models were the only choice I had if I wanted a skimmer. I had read really good things about this skimmer so I decided to give it a shot.

I am glad I did because this skimmer is working very well! It has only been on my tank for about a week or so but it's already removing nasty stuff out of my tank and cleaning it is a piece of cake.

The installation instructions lack considerably, but it's easy enough to find information about it on the Web. Regardless, it is an excellent product and I would recommend this to anyone that needs a hang-on-back skimmer.

This is my second protien sckimmer. My first one, just didn't do the job and added a bunch of bubbles to my tank, in a bad way. This one was cleaning green slime off my tank the first day. It does have some bubbles coming off of it, but nothing anywhere near as bad as the previous skimmer that I had. Also I have noticed they are getting less and less. Over all it is a great skimmer.

I have this skimmer on a 55gallon reef tank a very small sump. The skimmer works flawlessly right out of the box. Cleaning the bubble chamber and outflow areas is difficult but it has needed a tear down only once in over a year of service. One warning is to watch for overflow from the collection box if adding supplements, or changing water, chemicals, or using superglue, since the salt water will end up on the carpet

I bought this to replace the Hydor Slim Skim in my 55 FOWLR that I'm changing over to a reef. The Hydor worked okay but it simply doesn't have the capacity of the Octopus. since you don't really need a sump for a 55 gallon show tank I chose the HOB route and I can honestly say this is probably about the best HOB skimmer on the market. Although a little pricey, it's not much more than the CPR skimmers and does a WAY better job. It cost less than half as much as a Deltec(overated and way overpriced,considering build quality) MC-600 is better made, and does just as good a job if not better. the normal break in for the Octopus is 2-3 weeks but mine was pulling dark, tea colored,smelly skimate in 3-4 days. In the next 2 weeks i found the "sweet spot" on the skimmer cup and marked it and now it is filling the cup with the same every 4-5 days. After 3 weeks of use there are still some micro bubbles but there are far less than in the beginning. Do not use the sponges that come with the skimmer as they will probably become mini nitrate factories over time. On a 55g glass show, the intake tube DOES NOT need to be cut and doing so will probably void your warranty. As far as noise it started out a little noisy at first but now it's fairly quiet and I attached a 2nd piece of tubing to the air silencer. Basically all I hear is a faint "sucking" sound from the intake tube,so the unit is pretty quiet although not totally silent. This is agreat skimmer for tanks under 90g and I higly recommend it.

This is the first skimmer I had bought; and unfortunately even though I have a sump on my tank; it was simply too small for any of the internal ones on the market. So I purchased this one. It certainly is a pretty good skimmer, I wouldn't classify it as something that you could run on anything above the rated specifications, but it does a decent job on my 46 gal with a 10 gal sump. It is a little loud; but nothing unbearable to have in your room if you are use to sleeping with a fan or something similar to on. I would certainly say that if space is a limitation you have, this skimmer would work well!

So far so good. Using on my 37 gal reef with no sump. Took some time to properly adjust the collection cup, but now I get lots of tea colored skimmate every few days. I like that it has the pump on the outside of the tank, so I can barely see the intake and output inside the display.

I have have my Reef Octopus Hang on the Back 1000 OCT BH1000 for over a year now. It works, never fails, and cleans up easy. For those of you with Bio- cubes or Nano cubes you know it can be a challenge to find a skimmer that will work on your system. This Octopus fits perfectly and works great!!!!

I tried an Odyssea skimmer on my 75 FOWLR tank and was very disappointed, cheap but a waste of money. Thai skimmer worked out of the box. There were micro bubbles at first but after two days running, gone. It produces lots of skimmate and is super easynto maintain. It's a great design and loaded with quality.

I had few skimmers before, but once I saw this unit skimming, I immediately knew, all past skimmers I've had were junk. This HOB is a work horse, and I am completely satisfied with this purchase. Amazing skimmer, best I've had.

This is probably the single best purchase I made for my Nanocube 28. It skims like crazy. The water is always crystal clear. Highly reccomended.
