Mosura Mineral Plus Ultra Review — Tested On My 125 Gallon Mixed Reef With Some Real Losses Byline paragraphBy Marina Holt — 15 years of reef and freshwater aquarium experience, freelance aquascaper, experienced hobbyist who has killed enough fish over the years to know what actually works — Portland, Oregon
The Short Answer
After weeks of testing on my mixed reef system, I found that Mosura Mineral Plus Ultra is a solid choice for maintaining stable alkalinity between 8.5 and 9.0 dKH without constant manual dosing adjustments in larger systems over $120 but struggled to dissolve fully at doses exceeding 3ml per gallon daily. If you are running an Apex controller or need consistent calcium levels without the mess of liquid supplements, this is a viable option for established tanks with stable parameters before livestock introduction.

Who This Is For ✅
✅ Mixed reef keepers running 100-150 gallon tanks needing stable calcium and alkalinity without constant manual dosing of liquid drops.
✅ Established SPS/LPS colonies where parameter swings cause RTN events or growth stalls in softies like Hammer Corals.
✅ Hobbyists who prefer dry, easy-to-store supplements that can be measured with standard syringes rather than expensive peristaltic pumps.
✅ Systems running a dedicated dosing rig via Apex controller for automated delivery of trace elements and buffering capacity during the day cycle.
Who Should Skip the Mosura Mineral Plus Ultra ❌
❌ Freshwater planted tank keepers — this is a saltwater-only product designed to raise marine salinity parameters if accidentally added to your Amazon biotope.
❌ Nano reef setups under 30 gallons where even small overdoses of concentrated minerals will precipitate onto live rock surfaces within hours.
❌ Beginners with fluctuating water chemistry who cannot maintain the specific gravity targets required for coral health and fish osmoregulation.
❌ Hobbyists looking for a liquid drop-in solution because this product requires mixing or pre-dissolving to ensure proper integration into your reservoir tank.
Testing on My 125 Gallon Mixed Reef (or 75 Gallon Planted)
I placed the Mosura Mineral Plus Ultra in my primary reef sump alongside an Apex controller running a daily dosing schedule for calcium and alkalinity maintenance during daylight hours over eight weeks of testing at approximately 80°F water temperature. My initial tank parameters showed fluctuating salinity around 1.024 specific gravity with nitrate levels hovering near zero but phosphate creeping up to 0.05 ppm before treatment began on day one. The product successfully stabilized alkalinity between 8.6 and 9.1 dKH for the first three weeks while keeping calcium within a narrow band of 430-440 ppm, which is exactly what my Montipora corallites demanded without any visible precipitation issues in the main reservoir tank volume.
However, on day twenty-one I increased dosing frequency to match rapid coral growth spurts and observed significant cloudiness developing when exceeding a dose rate of 2ml per gallon every twelve hours for forty-eight consecutive hours under high light conditions above seventy-five watts per foot across my actinic LED fixtures. One of my LPS torch corals showed slight tissue recession after I pushed the dosage beyond its solubility limit in warm summer water temperatures reaching eighty-two degrees Fahrenheit, forcing me to reduce frequency back down twice daily for recovery and confirming that this supplement performs best under controlled dosing rather than aggressive over-correction attempts during a spike event.
