Shrimp tank guide
Shrimp Tank water parameters in context
Shrimp care gets easier when the numbers live beside the story of the tank. Use this guide to understand pH, GH, KH, TDS, temperature, ammonia, nitrite, nitrate, and the care notes that make each reading useful.

Short answer
For a shrimp tank, the water parameters to understand are pH, GH, KH, TDS or conductivity, temperature, ammonia, nitrite, and nitrate. You do not need to turn care into paperwork. Keep a steady tank history, add context when something changes, and the record starts to work like memory.
Quick reference
- pH: acidity or alkalinity, best reviewed as a stability trend.
- GH: general hardness, mostly calcium and magnesium, connected to molts and remineralized water.
- KH: carbonate hardness and buffering capacity, especially important when comparing Neocaridina and Caridina setups.
- TDS: a broad dissolved-solids trend marker, not a replacement for GH, KH, pH, ammonia, nitrite, or nitrate tests.
- Ammonia, nitrite, nitrate: nitrogen-cycle readings that help shrimp keepers spot waste and filtration changes.
A shrimp tank water parameter log works best with context
The useful question is rarely one number by itself. A clear log connects the reading to recent care, source water, species, and colony behavior.
| Reading | When to test | What to record with it |
|---|---|---|
| Ammonia and nitrite | Test first when shrimp are dying, gasping, inactive, or the tank is new. | Record the value, test date, dead shrimp removed, filter flow, water change, and what you did next. |
| pH, GH, and KH | Use these to understand mineral context, buffering, molts, and differences between Neocaridina and Caridina setups. | Record the test method, water source, remineralizer, recent water change, substrate age, and species or line. |
| TDS or conductivity | Use it as a trend marker, especially for Caridina, RO water, and remineralized setups. | Record source-water TDS, prepared-water TDS, tank TDS, remineralizer routine, and recent top-offs. |
| Nitrate and temperature | Review these when feeding, maintenance, room temperature, or stocking changes could explain a shift. | Record feeding, plant trimming, filter cleaning, heater behavior, room changes, and recent colony behavior. |
Good shrimp tank water parameters depend on the shrimp
There is no single perfect shrimp tank range. Shrimp line, substrate, remineralizer, tap water, RO water, and tank age all matter. Use these as starting points for Neocaridina parameters, Caridina parameters, cherry shrimp water parameters, and Crystal Red shrimp water parameters, then learn what is normal for your own colony.
| Parameter | Usual range | Why it matters |
|---|---|---|
| pH | 6.5-7.5 | Common cherry shrimp water parameter range for stable tap-water style tanks. |
| GH | 6-8 dGH | Keeps minerals in view when you are watching molts, shells, and remineralized water. |
| KH | 2-4 dKH | Helps explain pH stability in many Neocaridina setups. |
| TDS | 150-250 ppm | Useful as a trend marker once GH, KH, and water source are understood. |
| Parameter | Usual range | Why it matters |
|---|---|---|
| pH | 5.5-6.8 | A common Crystal Red shrimp water parameter range when active substrate is doing its job. |
| GH | 4-6 dGH | Often managed with remineralized RO water for more controlled mineral content. |
| KH | 0-1 dKH | Low KH is typical for many soft-water Caridina tanks. |
| TDS | 100-150 ppm | Most useful when compared against your own water source and remineralizer routine. |
Notice changes without making care feel heavy
A useful shrimp tank history should feel like a steady companion, not another chore. Instead of reacting to a single number, you can see the reading beside water changes, feeding, molts, losses, and colony notes.
How Shrimp Tank helps
Shrimp Tank is an aquarium app built for shrimp keepers. It is a care companion for the small details that matter later: the water change, the molt, the quiet week, and the reading that finally explains a pattern.
Keep each tank's readings, changes, care tasks, and journal notes together, then build a living history for Neocaridina, Caridina, Sulawesi, Amano, or mixed shrimp tanks.
Shrimp Tank treats parameter ranges as starting points, not promises. Set custom targets for your shrimp, water source, substrate, and mineral routine, then let your own tank history show what steady looks like for that colony.
