  7. What if we could 3D print our aquascape?

    3D printing could very well take our hobby to the next level of sustainability. 3D printing may have a place in aquaculture. It could be used to mass produce various size shells for hermit crabs, even species specific shells that are hard to source. Anyone interested in aquaculturing hermit crabs for clean up crews will have to source shells that are cheap enough to be competitive with wild caught hermit crabs. 3D printing might be a solution. Some basic designs, and intricate ornamental...
  8. Durso Or Stockman Standpipe? Wow! What A Difference!?

    I decided to finally quiet down my CPR CS90 overflow after years of the gurgling and sucking sound in the background. Wow! What a difference!? It only took about 10 minutes to build. Since I had to wait 24 hours for the glue to dry right for safety for the system, after building the Durso. I decided to use the Stockman standpipe first because no glue is needed.
  9. DIY Universal Battery Backup For Your Reef

    A few days ago (3/2/2018) I lost power in the recent Nor'easter. I had a battery backup system in place, and thankfully it functioned fairly well. However, I had upgraded my aquarium since I had originally planned out the battery backup and the system did not last nearly as long as I wanted it to. The battery took frequent recharges from my car to keep going. I've since re-evaluated my system and in the process, decided to write a post about general-purpose battery backup designed for reefs....
  10. DIY LED Wall Mount! Check it out!

    Hey guys! I decided to post up my diy led mount for anyone who is looking for a sleek idea and or just a way to hang their lights. I will definitely say I’m not the original person who came up with this idea. I see many who use tv mounts however I haven’t seen anyone do it like this. Either way I would like to thank everyone who has used similar ideas as it helped inspire me to do this.
  11. Cave Tank Build Tutorial

    Hows it going, thank you for joining me on this build. One day I was watching a nature show and saw this deep sea scene with hot volcanic spouts and shrimps on them and I said "I want one" and on the journey I went to find me a cave tank. I already had a pretty good feeling that this wasn't going to be something you can buy and so I decided to make me one. I took me a couple weeks to fully complete, but in the end it came out great and I loved every second of it. This is that build and how I...
  12. Heating large tanks with your gas hot water heater. Save 40% on energy cost!

    On average, 40% (±15%) energy cost savings over electrical heaters (depending on how efficient your hot water heater is). For my tank (I have an abnormally cold basement), I use 1500w of heaters and temperatures drop slightly at night. I also have a 1000w metal halide lighting system, which takes over most of the heating for 8 hours. But I figure I can say I average 1500w of heating 6 months out of the year, for half of the day. So my yearly heating cost of my tank is approximately $375....
  13. Automatic Frozen/refrigerated food dispenser

    I wanted a way to automate feeding of diverse and healthy foods to both corals and fish. Dried coral food and pellet food in an automatic fish feeder are decent options, but picky fish tend not to get fed, smaller foods are hard to accurately dispense, and the variety of the food is lacking. There have been successful attempts at frozen food dispensers, but they are too complex for my taste. So I made a refrigerated food feeder. The hardest part of this by far was getting the preservation of...
  14. LED Diode Replacement – Instructional Article

    Over the last few years, we have seen more beginner and moderate reefers becoming more and more inclined to attempt DIY projects. Anything from building a custom roller mat or an algae turf scrubber to attempting a stand build using two-by wood. With LED’s becoming more popular, the need for changing diodes for spectrum preference changes as well as burnt out diodes is becoming more of a norm.
  15. Feeding Fish and Corals

    Feeding Fish and Corals I have seen many videos and articles from people around the world making their own food recipes, the general Idea is to mix all different foods together so that each fish and coral have their daily nutritional need. My Tank is a 180 Gallons reef tank with emperor angelfish, purple tang, yellow tang, blue hippo tang, some clowns, wrasses, gobies and anthias. The angelfish and tangs are eating machines and need verity of mixed and nutritional food to keep them healthy...
  16. Magnets and Your Tank

    Who doesn't love playing with magnets? I do. Magnets are very handy for attaching equipment to our tanks - frag racks, probe holders, float switches, filter sock holders, small skimmers...etc. How do you know if the magnets you're using are "reef-safe"? I'm going to break down the two main types of magnets commonly used in our aquariums and cover the pros and cons of each. Using the wrong type of magnet can have adverse effects on your tank's inhabitants, so this information is very...

  18. The BulkReefSupply Brine Shrimp Hatchery

    Ever notice how many spare parts you can accumulate from reef equipment that you buy? What do you do with all these parts?! Well, I have a mandarin that is doing well, but I wanted to make sure that he was getting all the food he needs. I decided to look into a brine shrimp hatchery. $120....$70...what!?! No way I was going to get any of the reactors on the market with those prices, so I went to the random drawer to build my own. Here's how I did it (and how you can too)...
  19. Tired of accidentally leaving the water on?

    Have you ever been awakened in the night to the horrifying realization that you accidentally left your RODI system running? You rush groggy-eyed through your house in hopes that this nightmare somehow isn't real. SPLASH! As you step into the utility area, garage, washroom, or wherever you have your unit mounted, your foot lands in a growing flood of purified water which has (at least) left you with an enormous mess or (worse) resulted in a flood that has ruined flooring and/or property... If...

  22. How To: Connecting a DIY LED to an Apex Dimmable Outlet

    I’ll admit I jumped on the LED bandwagon pretty early on but at that time, there weren’t a lot of good fixtures IMO and none that really suited my needs. I did a ton of research and eventually decided that I would just have to build my own. I gathered all of the supplies and set out building. I ended up making a 36” x 8” fixture with 36 LEDs (blue and white mix) and a 4 LED moonlight addition. I have since swapped out some of the white and thrown in some red and green along with 4 UV LEDs....
  23. Low pH issues?? Make your own CO2 scrubber!!

    I'm a stickler for stability, and you might be too. Are you experiencing some pretty dynamic and erratic pH swings? I've seen pH in my system as low as 7.5 and never got higher than 8.1 . So my search was on searching for causes. After searching throughout R2R, I did a couple of tests and determined that CO2 was the culprit...

  25. A Simple Fix for Low PH

    When living in the warm weather or cold weather climates, we really do not have the chance to open our windows that often. This leads to a build up of CO2 in the air inside the house and results in a drop in pH. When our pH drops down to levels that are alarming in our reef tanks, we start asking ourselves why and how can we fix this in order to keep our reef healthy. Here is a quick and simple way to raise the system's PH within a closed-up house...
