The box doesn't have to be the daiso box , any identical box can be used , best if custom to your sump compartment size. The one I'm using is 9 by 6 inch I think. The reflector I used was a spare which I kept for like 10years in the storeroom haha

When all is ready put them in the sump, lights on for 18-20hrs a day. U will get slime algae at first , clean them up ,the lush green algae will follow after that. Most important is the led must be a 3watts 660nm red led . Harvest the scrubber when u get lots of algae u may throw away all or leave some in the box. To harvest just lift up the top light box and remove the algae. U will get salt deposit on the acrylic light cover , clean it if it gets too thick and blocking the lights. The acrylic will get dull white after sometime , just buy a new one and replace.

Once u get the height correct , u can glue the pipes together or maybe not ,it doesn't matter. But do not glue the top light part to the bottom part.

Next , cable tie the frames to the box , the light box and the algae box.

Next .... How do u get it to float?? ALA santamonica surf scrubber? Mine don't float ..haha

The algae box U need a algae screen (can buy from Artfriend those people use for knitting) Cut out the screen to size and roughen it with a stake knife then glue to the bottom of the box , u can add more strips of the screen to maximize algae growth area. Turn over the box and drill a hole in the centre and cable tie an air tube for the air bubble.

Led Light box . Place the reflector into the box and bolt down together with the led light and driver. Secure the driver with cable ties and connect the driver to a wire and plug. Last secure the clear arcylic with cable ties to prevent water splash.

Let's start with the equipments. Air pump Clear acrylic sheet Air tube Aluminum reflector Led lights DIY 2 daiso box Algae screen rough PVC pipes and angle joints Cable ties

Hi everyone , I have received many pm about the scrubber I've been using , how to build them , what kinda LEDs, do I build and sell them and many more request ..

Ahhh yes this is correct , water level will drop from evaporation in the last compartment but water level of each compartment will follow the water level from where it flow out .

That sump will do fine , your water lvl is wrong 1st and second compartment will have the same water level , the last will have less water due to return pump , u can however make all lvl same buy adding in more water till all water level is over the baffle plates. The last baffle plate can be removed coz it's redundant and will cause stagnant water at the top .

Got my hands on some zoas , actually zoa will die in my tank , I dunno why. Except those that are already with me from the start , any new zoa that I add will die in a week , recently added some zoa frag ,with nice colour , pink? orange? Gold? Anyone can id

I have some blue anthelia if your intrested http://www.liveaquaria.com/product/prod_display.cfm?c=597+599+694&pcatid=694

Congratz!!! Cool looking tank .. !!

Finbir you are getting slime algae , which could indicate low lighting , i use to get this kinda algae until I changed to the 660nm LEDs. But you are already using the 660nm , quite puzzling that you are still getting weak slime. How is the no3/po4 of your tank so far? Are u feeding your tank well or holding back on feeding? UAS is the best scrubber coz it's underwater and is in full maximum contact with the water, just that algae will grow on the glass , that's the downside..

And Yes if the light escapes and shine onto the bottom ,sides glass and other equipments .. Algae will grow on them , I have algae growin in my skimmer and calcium reactor too

Some pics ..

Hi bright , all these algae are present due to the nutrients ,nitrates and phosphate that are present in the water and rocks. U just need to remove these elements and they will go away. There are lots of method or removal and since you have chosen to go the scrubber way then I would say it's a very good method , it has it's pros and cons as well. If U have been reading up in the algae scrubber forum . Then u should know there are 3 types of scrubber , they evolve from one another due to the cons. 1st waterfall scrubber ,lots of salt spray and water splash 2nd the UAS , upflow algae scrubber , algae will grow on the glass difficult to remove and will cause algae to be sucked up to DT. 3rd the floating scrubber , santamonica surf scrubber , best I think so far just need to lift up the light and pull out the algae and throw away. I've DIY all 3 and currently using the 3rd version. Not floating but i built it so that the algae screen box is just submerged in the water with the lights few inches above , using PVC pipes , need a bit of ideas and design to pull it off , customed to my sump design. Most important is the light needs to be a 660nm red led , other wavelengths and the algae will not be so great.. Still works but not so efficient , that's y some people decom the algae scrubber co they can't get the correct algae growing I guess. Wow I wrote too much..!!

Got them off Ebay , the seller did not post them anymore but maybe u can pm him as ask him to put them in. I did that the last time I bought them.

Oh , u are discribing an upflow scrubber the previous one I had. I've made changes on my current one I mentioned above , that a so called 'floating scrubber' almost same as santamonica surf scrubbers.

This is the algae screen and box , the holes are where the air bubbles comes in from. Air bubble tube go from below the box so the don't get clogged with algae.

The light is correct , there should be no problem. Did u put air bubble at the screen ? And screen and light should be just inches away.

Hi finbir , can u post a picture of the setup , the light set and the scrubber screen , and where u in the sump u set it up

Thanks bro, video quality not so nice dunno why, shot with an iPhone but looks better and clearer on the phone.
