I know I can't be the only one tired of the smell that comes with cleaning skimmers, so I started this tank with the intent of never needing to run one. I decided to instead run just an algae scrubber, the only methods of filtration will be it, (a Clearwater scrubbers mini model scrubber) and filter socks.

The itself tank is a custom peninsula from aquarium masters measuring 36x24x18, the stand was made in the wood shop of a local store, and the color was decided without my approval or ability to argue. As far as equipment goes, I decided on a skimz sumpro 36 sump, a vectra M1 return, two vivid creative aquatics random flow generators nozzles for the returns, a radion G3 pro for the light, and two mp10qds which I plan on putting on should I need additional flow.

So let's get into things!

First off, the overflow sucks, I forgot how large aquarium masters overflows were, I love the tank, but with an over flow that size I expect at least 1.5" and 1" holes, not a 1" and a 3/4". I ended up using both of these holes for a bean animal style overflow, and running my returns up over the back.


Second, the sump, normally I build my own sumps or have them made locally, unfortunately my buddy who does acrylic was too busy, and I was too lazy, so here we are. I really don't have anything negative to say about the skimz sump, it looks good, and does it's job. The only room for improvement in my opinion is the top off section, it's comically small. Unboxing it was definitely fun though!

Now let's talk about the big part, the scrubber, I have Clearwater scrubbers on all my tanks, and all my clients tanks, I love them, and from personal experience, they work better than the two other brands I've tried, which is why I assume brs carries them. I plan on stocking this tank pretty heavily, so I'm excited to see how the new mini model of scrubber I am testing out performs, it's model number is CW-50, and I have no problem bragging about the fact that even BRS doesn't have them yet! The mini one is aptly named, measuring just 6x6. It is pretty though! I jumped for the optional light covers, because no one likes purple rooms.

Plumbing was uneventful, if you've plumbed one tank you know how it's done, 4 unions, 3 gate valves, flex line, and sch80 return lines up over the back. Nothing special. Oh and sand, I added 60lb of sand the day I plumbed and filled, leaving it looking like this! (Stickers have since been removed)

Well, that's pretty much it for setup, all I'll add in is that on every tank I do, I fill and stock lightly day 1, it's probably been 5 years since I've actually "cycled" a tank the "right" way. The tank had 30lb of live rock added day one, and had pro bio dosed daily to make up for this.

Next post will detail stocking and future plans!

I'm interested to see how it goes.
I've had nothing but success so far with them, as a side note, I have 0 plans of doing water changes on this tank, I plan on dosing trace elements, calcium, mag and alk, and that's it!
 
I ran a DIY Algae scrubber on my Red Sea Reefer Nano SPS dominant as the only filtration for about a year, worked fantastic. I started running a skimmer as well at a certian point for aeration not really for filtration. It takes a bit to get seeded and working right but it will eventually do so, I found dosing Iron helped it to keep growing well.

Yep, in my experience it's about a month before they get running right, sometimes a little more. Once they get going they do wonders though! I've never had to dose iron, but I'll definitely keep it in mind if I ever see a growth drop off.

On an unrelated note, I'm tempted to get 3 baby purples and toss them in here to grow out for one of the big tanks, I can get them about quarter sized, and while I know they'd have to come out eventually, they'd add a bit of color until then. So far for fish I've just got a diamond goby and a pair of clowns. I've also been tempted to add a half dozen or so Talbots damsels.
 
Just bought a CW 50 myself. Using a Sicce 185gph and the gurgling is too much. Set pump to lowest setting and will install a ball valve. What pump did you pair with it?

I'm using a 2000lph coral box pump turned down to the lowest setting. I took care of the gurgling by running both the main drain and the emergency down to below the waterline of the sump. My filter socks actually make more noise than it now

Also, update time. Everything looks good so far, I added 2x occelaris, a cleaner shrimp and a diamond goby day one. In addition to this I added an assortment of lps and sps from my main tank to "test the waters"

Only complaint so far is how comically small the ato section on this sump is!

The scrubber was plumbed in Saturday, making it exactly 6 days since it's addition. As of today it already has small amounts of algae growth!

Just a quick update since today was my weekly scrubber cleaning day! This thing is a monster! 0 nitrates still, I'm currently feeding 3 cubes of mysis daily, reef roids in the evenings, and dosing 20ml of red sea reef energy A & B every day. Normally I also dose marine snow, but I ran out last night.

Really glad I made them send me the then test demo of the cw-50 instead of going with a cw-100!
