Freshwater Supplements
Healthier Water. Happier Fins.
Liquid supplements and mineral blends formulated by hobbyists, for hobbyists. From first-cycle to prize discus — we speak your parameters.
The Tank That Cycles Itself.
Cycle Time
7 days
vs. 4–6 week fishless
CycleStart — Concentrated Nitrifying Bacteria
Seeding a new 20-gallon shouldn't mean six weeks of cloudy water and dead-eye ammonia spikes. CycleStart delivers a dense colony of Nitrosomonas and Nitrospira — the exact strains that colonize your filter media — so your cycle completes before your plants even hit their first trim.
- Establishes nitrogen cycle in 5–10 days
- Safe for shrimp, nano fish, and sensitive species
- Doubles as a re-seed after medicating with antibiotics
- 1 mL per 10 gallons, dose daily for first week
"Dosed CycleStart on day 1, checked ammonia on day 8 — zero. I've never had a cycle go that clean on a new tank."

MineralDrop GH/KH+ — Precision Electrolyte Blend
RO water is a blank canvas — but blank water stresses fish. MineralDrop re-introduces calcium, magnesium, and carbonate alkalinity at the exact ratios your setup demands. Whether you're dialing a 6.5 pH for your Apistogramma pair or building the 150 ppm TDS your Caridina colony needs, one formula, precise results.
- Formulated for RO, RODI, and soft tap water
- Separate GH and KH control — not a 2-in-1 compromise
- No sodium, no chlorides — shrimp-safe
- Tested against Salifert and API kits

SlimeShield — Aloe & Herbal Stress Coat
Transport, netting, new tank syndrome, fin rot — every stressor strips your fish's slime coat faster than it can regenerate. SlimeShield rebuilds it in hours, not days, using pharmaceutical-grade aloe vera and a proprietary herbal extract blend shown to reduce cortisol markers in stressed cichlids by 62% in our internal trials. Dose at water changes; double-dose after any netting event.
Slime Coat Repair
Rebuilds protective mucus layer within 4–6 hours of dosing
Herbal Immune Boost
Echinacea and calendula extracts for natural immune support
Dechlorination
Neutralizes chlorine and chloramine on contact — no wait time
Invert Safe
No heavy metals, no EDTA — safe for shrimp and snails
"My halfmoon betta had fin rot so bad I thought I was going to lose him. Two weeks of SlimeShield and clean water and his tail is basically fully regrown. This stuff is the real deal."

"Running a 75-gallon discus tank for eight years and I've tried every supplement on the market. Aqua's MineralDrop is the first product that actually holds my KH without swinging my pH. Parameters have been locked for six weeks."

"I breed bettas and sell on Aquabid. Stress from shipping is the number one cause of loss. Since I started double-dosing SlimeShield before bagging, my DOA rate went from 8% to under 1%. My buyers have noticed."

"Set up my first Iwagumi with Caridina shrimp. Everyone told me the cycle would take months. CycleStart had my ammonia at zero by day nine. Shrimp went in on day twelve and they're still alive three months later."

"The dosing chart PDF is genuinely the best piece of fishkeeping education I've found outside of a textbook. Gave it to my LFS and they started stocking Aqua the next week."
