This skimmer will work well in 7"-9" of water. Feel free to let us know if you have any further questions!
This could work with a very light bio-load not too many fish, most likely around 4-5 and a lite feeding. Feel free to let us know if you have any further questions!
If you are looking for a skimmer that has a feed for the water intake we would suggest looking into a recirculating skimmer since they require some type of source to be fed into the skimmer from another pump, or overflow. By plumbing a source water into the intake of the venturi you may change the characteristics of how the pump runs and pulls air.
Just an FYI the protein skimmers we carry are designed to work with saltwater only and will not be effective in freshwater.
The footprint of the skimmer is about 11x7 so you will want to make sure that you have atleast that much space for it.
I apologize for the broken "Questions" feature, I'll have our web team look into it if they are not already aware of the issue.
For the initial water level setting I would set it at the wavy line on the skimmer body and adjust from there as the skimmer breaks in and you can determine how the skimmer behaves in your particular set up. If you are not getting any skimmate in the cup after 24 hours you can slowly raise the water level in the skimmer until you do at which point you can make fine adjustments to get the desired amount of water/skimmate in the cup. Some people like to skim "wet" (lighter colored liquid) while others like to skim dry (darker colored liquid).
I hope this helps!
Have a great day :)

Unit to big for sump By JimA on 3/29/2016JimA wouldn't recommend this product to a friendIt is so big it will not fit in the sump I am not sure what to do with it
Loved until pump died By Ryan on 3/20/2016Ryan wouldn't recommend this product to a friendAbsolutely great skimmate produced after just a few days. Short break in period. I haven't even owned this one month and the pump stopped working. Hope BRS will replace.
Excellent By Xecros on 3/14/2016Xecros would recommend this product to a friendI just recently bought this Skimmer in preparation for building my tank. I did a lot of review readings, and comparisons to other makes and models. Probably a good solid 48 hours worth of research.
For my tank size (55 gallon), for the price, this skimmer is hands down, the best you can get.
Having said that, there is a problem with balance, (stability). Fully assembled, without any water, not running, it will stand on it's own. But, it will easily tip over with the slightest pressure. If your going to remove the skimmer cup for cleaning, use 2 hands! One hand to hold the skimmer in place, the other hand to pull off the skimmer cup.
My plan to overcome/fix this annoyance, is to silicone the damn thing in place. I plan to use 3 or for dabs of silicone, and silicone it in place. Kinda like spot welding, I'll be spot siliconing the bottom of the skimmer to the sump itself.
Great Product By crabs_mcjones on 3/5/2016crabs_mcjones would recommend this product to a friendI upgraded to this unit from the Seaclone 100 and have noticed a night and day difference. This skimmer works excellent and is a grwat buy at a great price.
Wonderful Skimmer By James on 2/21/2016James would recommend this product to a friendI love this skimmer. The pump is super quiet, and the collection cup has a waste drain that i port to an empty wine bottle. I cant really fit my hand into the skimmer for cleaning but that is not worth subtracting a star over due to the great value of the skimmer.
Great for the money By Chase on 2/5/2016Chase would recommend this product to a friendThis skimmer works real well. It is quiet and effective. Although, the break in period was a bit long for me. However, that could have been due to the fact that i have this thing running on a system of 35 gallons total water volume. I have owned this skimmer for a while and the higher the bioload gets the better this thing performs. It skimmed wet for me at first but i only had one fish so you could say it just didnt have enough to skim out in the first place.
The best entry level skimmer By Yak on 1/3/2016Yak would recommend this product to a friendI tried this, the coralife super skimmer 125, and the aquac urchin pro. I like this one the best by far. Easiest to dial in, starts pulling black crud out immediately.
Awesome Skimmer! By Jeremy on 11/15/2015Jeremy would recommend this product to a friendI had this skimmer on a 65g mixed reef, and it's the best skimmer I've ever used. It pulls out skimmate that has the consistency of chocolate pudding, The gate valve makes fine tuning this pretty easy and a foam head forms almost immediately. Even though the directions were pretty terrible, it doesn't take more than 5 minutes to assemble. I gave it a 5/5 despite the poor directions because it performed so awesome. I'll definitely be using the classic again when I upgrade.
Unstable, tough to tune By Geekymitch on 11/10/2015Geekymitch would recommend this product to a friendSeems like a decent enough skimmer...but trying to adjust to get a nice dry skimmate is virtually impossible. It's either wet, or it's not at all. Incredibly frustrating. Because of the weight of the pump and it being outside the skimmer, the thing is also very prone to tipping - like, every time you try to remove the collection cup.
INCREDIBLY sensitive to change in water level - I built a stand for it, which works ok...but since it's also very prone to tipping, it's not the most ideal solution.
The sound of flowing water coming out of the valve is also quite loud...making this by FAR the loudest piece of my setup. I intentionally setup a bean animal to keep volume down, but this skimmer sort of made it a moot point.
It is what it is and in some ways you do get what you pay for. This is an inexpensive skimmer, and it behaves like it from a design perspective. I does remove crud from the tank, albeit usually found in the water that flows out of the collection cup rather than in the cup itself.. It will certainly do fine while I'm just running softies in a massively understocked tank...but once I really start stocking, I'll likely be ditching this in favor of something with an internal pump, quieter operation, and more known for easy tuning.
great product, good construction By Mitch on 6/16/2015Mitch would recommend this product to a friendFor me being a newbie i really like this skimmer it was very easy for me to tune it and its very quiet
Pretty darn good skimmer for the price By Andrew on 5/18/2015Andrew would recommend this product to a friendBeen going strong for close to three years on my 75g tank. Pulls out some nasty gunk. A little finicky when dialing it in, but it does a great job at this price point. I think if I were to upgrade, I'd need to spend a significant amount to get a better result, so this is a very good value.
Stay away from Reef Octopus By California Mixed Reef on 4/9/2015California Mixed Reef wouldn't recommend this product to a friendBuy any other skimmer on BRS except Reef Octopus. If any issues they are not allowed by Coralvue to return the skimmer or refund your money. I have been going back and forth with their customer service after purchasing elsewhere and they keep giving me the run around. While the BBB rates BRS an A+, Coralvue (the company that makes Reef Octopus) is not accredited and has a rating of D. Before sending replacement parts or refunding they will want you to perform test on faulty equipment and send them video of the malfunction. I have filed a complaint on Coralvue (reef octopus) with the BBB. Keep away from any Reef Octopus item customer service is a nightmare.
