I have the 4, and it has no room for a larger skimmer and my tank is 220gl. Big mistake.
Wish I went BIGGER By ReeferGil on 10/3/13

I have a 75g tank and went with the model 3. One year after it's all been running, I have two major regrets. I wish I had larger stand doors and I wish I went with the Model 4. I'm running a Reef Octopus pin110 skimmer, GFO reactor, probe holder, float switch, Mag 7 return pump and ATO switch in the last stage. My last stage is soooo crampped, no space at all. The model 3 is 25.5" long while the model 4 is 36" long. Would have given me more room making it easier to clean and given me more options for a larger skimmer if I wanted to upgrade later. Other than that, I've had no issues. Chaeto is growing great under LED lights and no leaks. Runs as designed.
The sump is OK just not with a refugium By Saboken on 8/18/13

For the price there should be more options to use this as a Refugium the barrier between chamber 1 & 2 has no way to lock it in place when/if the power goes out the Barrier drops and messes up the flow in my Refugium I could modify it but if I do and anything goes wrong like the first unit that was not glued together right I will be in my own since it will void the warranty if I drill it in any way, Aqueon has a great customer service they sent me a new sump in 2 days and did not want the old one back but it leaks, if I find a way to secure the wall to the Refugium I will post it, If you are looking for a Berlin or want to use the optional bio balls I am sure this would be great But I have a Green Mandarin and have been trying to keep pods in the Refugium but the flow is to high and if the wall drops most of them get pushed into chamber 3 and up to the display tank they are eaten quickly.

i needed a sump for both my current 60 gallon and wanted something I could expand for my next tank a 100 gallon reef. This fits in my cabinet, is flexible for either refugium or berlin style sump and its nice and quiet!
Good for a starter sump By Casey on 3/6/13
Casey would recommend this product to a friend
I purchased the Model 3 ProFlex for my first saltwater system which is a 90 gallon tank. I can say that it was good for starting out, but I added a 15 gallon tank for my refugium because I did not have enough room to have a refugium, protein skimmer, and carbon reactor in it. I would not recommend drilling it for an external pump because the plastic walls are a little too weak.
Great By Tom on 12/27/12

I am very pleased with this product. It can be easily changed to fit your aquariums. It is great for reef aquariums with the advanced filtration. There is a lot of room to add a large Refugium and skimmer. You just need to buy a return pump and your ready to roll!
Makes a great sump By Chad on 12/16/12

I am very pleased with this product. It is setup as a modular unit that can be be easily made into any popular style of pump. I got a model 2 (set up Berlin style) for my 75gal reef and couldn't be happier with it.
It is held underneath my tank in a stand compartment and holds all my goodies. Reactor in/outs, heater, ATO, and over sized skimmer.
Good sump, needs a little modding By Ali on 11/12/12

I got the model 3 for my 120 gallon tank and at first i had my skimmer in the return chamber, witch was a bad idea since i was getting a ton of micro bubbles in the DT. so i removed the socks from the first chamber and plumbed thg skimmer in the first section added some live rock and made a nice 5 inch sand bed in the refugium and added some macro algae and cant complain . water is so clear and the skimmer is skimming all the nasty poo and uneaten fish food. and no bubbles in the DT any more. my only regrt i wish i got model 4 could have had more room in the first and second stage to have more live rock in it. P.S i added a 1200 maxi jet to the first stage so i don't have any detritus stuck under the live rocks and the skimmer does the rest so there is no need for any filter socks changes or cleaning, very maintenance free.
Shockingly quiet, great for a berlin, a stretch as a refugium By jeff on 11/5/12

The design is EXTREMELY quiet, i can just barely hear the water in the sump when i close the cabinet doors, this was my primary objective for this purchase. A lot of space is used up on the filter sock chamber so make sure that your equipment is going to fit in the other 2 chambers before buying. My skimmer is the diablo xs160 and it just barely fit in chamber 2 of the model 3. I played around with the skimmer in chamber 3 thinking i would pull off a refugium in chamber 2 but it just didn't work out mostly due to the fact that i couldn't get the water level in chamber 3 to the depth that was needed for the skimmer without having the water level being pretty darn close to overflow when all the power was off.
Solid Product By Joey on 7/9/12

I have the Model 1. It works very well, but could use a little more room in the return section, but other than that, everything is working great.
Good for beginners By Hannon on 6/17/12

I bought this sump thinking it was the latest sump technology, when in fact it isn't. The latest methods require alterations in the sump. The refugium and sump compartments are opposite of what many experts have recommended. Not many skimmers will fit in the compartment intended for it. I recieved a model 2 that just fits under my stand and have been working out how to make it do all I want. I recommend deciding which sump method you want and then seeing if someone has done it with that model.
Good product By Tom on 6/4/12

I found that this sump was well built and does its purpose well. The skimmer in the same chamber as the return pump is far from ideal but with some foam placement and a little trial and error you can make it work out without micro bubbles in the display tank.
If you have a skimmer that has the option to run your feed pump remotely like the Aqua-c ev series this totally solves the issue. But over all its a good purchase and worth the money if you dont want to mess with silicone and glass to make your own sump.
