Since we are all safely quarantined at home I wonder what DIY projects my fellow reefers have been up to? To start you off I thought I would share my DIY ATS. I wanted a small ATS to fit on my sump and supplement a refugium and weight for weight an ATS will remove more nitrates. Here is the cut list...(pic1) 5mm Black Acrylic • 210mm x 200mm (qty 1 for base. Mine was 150mm wide as I only planned on using one light due to my needs) • 100mm x 170mm (qty 2 for sides) • 100mm x 210mm (qty 1 for lid) • 150mm x 10mm (qty 2 for support rails) 4.5mm polycarbonate solid clear transparent • 200mm x 170mm (qty 2 for windows) • 199mm x 79mm (qty 1 optional for lid) Cost of materials was around $25 from Dama. Sales@dama.com.sg (ask for Yuki) I also picked up a 20w grow light from shopee $19 each. Then I needed some plumbing (pic2) cost was around $20. For my design I was going to have the water drain down into sump, so I wanted two drainage holes. One would be for main drainage and the other will have a taller pipe inside for emergency drainage. Pics 3 shows the diamond drill bit I used to make the holes and pic 4 the construction of the base using acrylic glue. The light will sit on the lip and the tank connectors are used to screw into the base for drainage (you could always have it come out of a side wall) Pic 5 is final construction. I used a 16mm pipe for the spray bar. Drilled in a few holes and added some knitting material for the GHA to grow. Pic 6... that lovely pink glow! Hopefully the GHA will be growing soon. Hmmm just have to finish the tank now hahaha. Anyways, what have you reefers been upto in Circuit Breaker?? Sent from Singapore Reef Club mobile app

That’s approx 92 gallons.

Also make sure your layering is 0.1mm or below to ensure better fuse from layer to layer. Infill 20% above. Overtime, poor layering can result in cracks. I experience this myself, thinking I can shorten the print time. Using a wider nozzle can help create a more solids part. 0.5mm is great. Save time too! Sent from Singapore Reef Club mobile app

Did you 3D print it with abs or hybrid filament. For pla and Petg they can deform easily over prolong period of heat. Pla material is organic, if in contact to salt water it may leak.. which is bad for your tank. Otherwise light fixture should be find as long as it doesn’t come in contact with water.

actually if u get a bigger vol tidal, it works as a wave maker too! I used 55 for my 2feet and never had to get a wave maker.. am letting it go for 60 if you are keen Sent from Singapore Reef Club mobile app

Next project: 3D printed a shade for my KESSIL H380 out of some Carbon Fibre filament. I designed the shade to hold a little 2mm diffuser plate, which a little piece of clear polycarbonate I wet sanded. I used polycarbonate as it won't warp if it gets hot (unlike acrylic). The idea is that this helps reduce the light spilling over into the sump and reduces the intensity as so I dont destroy the macroalgae. I picked up the Ender 3, 3D printer at cash converters for just $39 Bargin!. I do have a few ideas on what to print next for the tank but happy to hear any suggestions?? Happy DIY reefing!
