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

The light is IP65 rated. Which means it is suitable for outdoor usage (rain etc). Basically means it is protected against water splashes and spills. Sent from Singapore Reef Club mobile app

after more than a week, finally the GHA is reducing glad the hermit crabs are helping too. will not use Flux RX unless GHA wild spread again. Will let the urchin and hermit crabs slowly nibble on the remaining GHA

Nice. Maybe can try ramp time 2hrs up and down. [emoji1303] Sent from Singapore Reef Club mobile app

(Copying previous post on the subject...) RODI systems first removes sediments, silt, clay... The carbon filter and RO membrane remove any unwanted chemicals like chlorine, chromium, pesticides. The DI resin typically focuses on the removal of heavy metals like copper. Combined they remove impurities, microorganisms, disinfection byproducts, inorganic chemicals, organic chemicals, and even naturally occuring radioactive nuclides! Now whilst Declorinated tap water is okay to use short term all the above elements even in extremely small ppm/ppb will build up over time (Silicone even absorbs heavy metals). This will start to cause issues for you. Tap water vs. RODI... imho It's the difference between breathing in the haze and clean fresh air. Both will keep me alive, but I know which one I would prefer. Sent from Singapore Reef Club mobile app

Awesome. Good luck sounds like a great build. Keep posting. RSR just launched some new tanks so check those out (xl300?), slightly more width in the tank which also means more room in the sump and equipmemt area. That no doubt will always be welcomed. Do you plan on running an ATS or Refugium? Convert filter sock area for Roller Mat?? Either way good luck. Looking forward to seeing how you progress. Sent from Singapore Reef Club mobile app
