Hello! I have a 180g reef tank in my classroom for use in my Environmental Science classes (Grades 11&12). This thread will follow the building, filling, and growth of the tank. I have permission from the parents of my students to post pictures on a school Twitter account which is dedicated to the reef tank, and you are more than welcome to follow it to see updates on students work alongside any experiments or labs we do using the tank (www.twitter.com/monarchs_reef). I will not be posting students' pictures nor their work here, as I did not include this site on the permission slip. Here's a breakdown of what's in my tank: Tank & Stand Tank: 180g Aqueon w/ 2x corner overflows (6" x 2" x 2") Stand: Custom 180g Stand w/ canopy & glass top from LFS In DT: Sand: 180lbs Fiji pink live sand Rock: ~160lbs of what started as dry rock (ordered 180, have some left over in storage) Circulation Pumps: 2x WAV adjustable pumps Lights: 2x Kessil AP700 Sump Stuff: 40g Breeder Custom sump (created myself) Skimmer: Reef Octopus 202-s Protein Skimmer (placed on a 2" Tupperware container to raise it up) Refugium Lighting: Kessil H80 Tuna Flora LED + gooseneck mount Return Pump: Reef Octopus Varios Controllable DC Pump Reactor: BRS GFO & Carbon dual reactor (not yet hooked up) Heaters: 2x 300w Heaters (controlled w/ apex) ATO: Tunze Osmolator ATO (using a 10g tank as RODI water holder) Macro: Chaeto in a hampster ball to keep it from clogging return (was having strays slow down pump) Water: RODI: BRS 5 stage 75g per day RODI Salt: Instant Ocean reef salt (changing salts once I run out of current supply) Test Kits: API Master Reef Kit & API Saltwater Test Kit (getting better test kits when I run out) 32g Brute Trashcan - mixing saltwater (have cheap thermometer & pump) 32g Brute Tashcan - RODI water storage (use for freshwater tank & transfer to other can to make saltwater) Other: Apex Controller 35 Gal tank for Quarantine Fish (in the order they were added): 2x Ocellaris clownfish (Amphiprion ocellaris) 1x Diamond Watchman Goby 2x Banggai Cardnialfish (Captive Bred) 2x Orchid Dottyback (Captive Bred) Progression Pictures:Empty tank in the classroom: Aquascape in Empty Tank: Tank full, lights added!
