The other hydroponics-store staple in DIY plunge builds, and the Active Aqua's perennial sparring partner in Reddit comparison threads. The 1/2 HP EcoPlus (model 728707, street price around $1,090, list $1,687) is rated for up to 132 gallons, chills down to a claimed 37°F floor, and runs a pure titanium evaporator with a Japanese compressor in a galvanized steel housing — genuinely commercial-grade guts at hydroponics prices. Builders who choose it over the Active Aqua usually cite the titanium evaporator and the slightly lower street price; those who go the other way cite Active Aqua's larger 90–172 gallon rating and bigger build-thread paper trail. Same DIY rules apply: no pump, no filter, no weatherproofing — you're the systems integrator. For a 100-gallon stock tank in a garage, it's a proven, boring, effective choice, which is exactly the compliment it wants.
