Quick answer: Salty Shrimp GH+ (Bee Shrimp Mineral) is the top pick for caridina shrimp: it’s a GH-only powder that gives repeatable TDS results and works with active substrate. For nano tanks or fine-tuned dosing, SL-Aqua Blue Wizard is a strong liquid alternative. The key buying difference is GH-only vs GH+KH: caridina on active soil need a GH-only product, while neocaridina in inert tanks use a GH+KH product that raises both general and carbonate hardness.
When it comes to breeding Caridina shrimp, your success often comes down to one thing: precision water parameters. Remineralizing RO water is the gold standard—but only if you’re using the right GH+ product for the job.
In this guide, we compare the top GH+ remineralizers used in the shrimp world, breaking down dosing accuracy, ingredient quality, cost per gallon, and long-term stability.

What to Look for in a Remineralizer
- Only raises GH (not KH) – KH disrupts pH buffering and substrate function
- Accurate dosing – stable TDS and reproducible results every mix
- Safe for invertebrates – no copper, nitrate, or unstable compounds
- Fine powder or liquid – easier to mix and dose by the gram or mL
1. Salty Shrimp GH+ (Bee Shrimp Mineral)
Overview: The gold standard. Trusted by breeders worldwide for consistency, accuracy, and long-term stability.
- Powder-based remineralizer
- Raises GH only, no KH
- Use 2g per 10L for ~100 TDS
- Excellent long-term buffering with active substrate
- Cons: Not the cheapest—but you get exact, repeatable results
Rating: ⭐⭐⭐⭐⭐ – Most recommended for serious breeders
2. SL-Aqua Blue Wizard
Overview: Premium Taiwanese blend designed for precision Caridina systems. Excellent for shrimp breeders who want crystal-clear water with mineral trace balance.
- Liquid GH+ remineralizer
- Precise dosing per mL for TDS control
- Great for smaller containers or nano tanks
- High purity, easy to mix instantly
- Cons: More expensive per gallon than powder
Rating: ⭐⭐⭐⭐½ – High-quality choice for small or fine-tuned systems
3. Dennerle Shrimp King GH+
Overview: European-made GH+ powder with similar results to Salty Shrimp. Slightly more expensive but often easier to find in Europe or online retailers.
- Powder remineralizer, mixes easily
- Also adds trace elements like calcium, magnesium
- Dosage: ~1g per 10L (test to confirm TDS)
- Good value if bought in bulk
Rating: ⭐⭐⭐⭐ – Reliable, with good trace element balance
4. DIY GH+ (With Caution)
Overview: Some advanced breeders mix their own GH+ using calcium sulfate, magnesium sulfate, and potassium salts. This saves money—but introduces huge risk if mixed improperly.
- Only for advanced keepers with chemistry knowledge
- Risk of incorrect ratios or contaminants
- No trace elements unless added manually
- Requires frequent testing and adjustments
Rating: ⭐⭐ – Not recommended unless you’re highly experienced

Frequently asked questions
Which remineralizer is best for caridina shrimp?
Salty Shrimp GH+ (Bee Shrimp Mineral) is the most recommended for caridina. It’s a GH-only powder dosed at about 2g per 10L for roughly 100 TDS, and it stays stable long-term with active substrate. SL-Aqua Blue Wizard is the best liquid option for nano tanks or precision dosing, and Dennerle Shrimp King GH+ is a solid powder alternative with extra trace elements.
What is the difference between a GH-only and a GH+KH remineralizer?
A GH-only product raises general hardness (calcium and magnesium) without touching carbonate hardness, so it leaves KH at zero. A GH+KH product raises both GH and KH, which buffers pH higher. Caridina need GH-only because added KH disrupts the low pH that active soil substrate is designed to hold.
Do neocaridina need the same product as caridina?
No. Neocaridina (like cherry shrimp) live in harder, higher-pH water in inert tanks and use a GH+KH remineralizer so both general and carbonate hardness rise. Caridina (like crystal red and taiwan bee) need a GH-only product because they’re kept on active soil that strips KH and holds pH low. Using a GH+KH product on caridina fights the substrate and shifts pH out of range.
How much remineralizer should I dose?
Dosing is by target TDS, not by tank size alone, so always test with a TDS meter. Salty Shrimp GH+ runs about 2g per 10L for roughly 100 TDS, while Dennerle Shrimp King GH+ is closer to 1g per 10L. Mix into RO water until you hit your target TDS, then confirm with the meter before adding it to the tank.
What GH and TDS should I target for caridina?
Aim for GH 4-6 and TDS around 100-130 for most caridina. Mix remineralizer into RO water (0 TDS) until the meter reads your target before water changes. Keep the number consistent between mixes, since swings in TDS stress shrimp and molting more than the exact value does.
Can I use one product for both shrimp types?
Not cleanly. A GH-only product like Salty Shrimp GH+ is correct for caridina but leaves neocaridina with no KH buffer, which can let pH drift. A GH+KH product suits neocaridina but adds carbonate hardness that’s wrong for caridina on active soil. If you keep both, buy the matching product for each tank rather than compromising with one.
