Водоподготовка для Crystal Shrimp

Повторю,коллеги оставьте TDS в покое. Принципиальное значение имеет только кальций\магний и микро.

Вот параметры, которым человек старается следовать в растительном креветочнике. Представляете,какой там может быть TDS?

Water Chemistry
I spent the most time and money in researching this aspect. Finally, I had perfected it IMO and I am glad to share with everyone on keeping planted shrimp tank so that no more shrimp will die or ugly plant growth.

Below is the optimum water chemistry for planted shrimp tank IMO:
- Temperature: 24 Degree C
- Lighting: Medium Intensity
- CO2: 25 to 30ppm
- pH: 6.0 to 6.4 (after CO2 injection should be 5.6 to 6.0; sweet spot of Molydate availability in this pH range is at pH 5.8 to 6.0. However if you add Molybdate replenishment during water change, you will ensure sufficient Molybdate at all time. I can grow my plant nicely without lack of Molybdate sign at pH 5.4 too)
- kH: 0 (If you are planning to keep high CO2 demand plant, you may want to do it at 2dKH)
- gH: 5.5 to 6.5 (according to the pH of above; lower the pH, the high gH is needed)
- Redox: No absolute value. My shrimp thrive from 300 to 600mV. As long as there is no unstable Redox, your shrimp is safe. If your Redox drop drastically (drop or increase 100 within a weeks or goes to negative), it is a sign of too much organic waste.
- Potassium: 15 to 30ppm
- NO3: 15 to 25ppm
- PO4: 1.5 to 2ppm
- Ca: 22 to 25ppm
- Mg: 8 to 11ppm
- S: 4 or more ppm
- Fe: 0.1 to 0.5ppm (depending on the type of Fe you are using; organic Fe can has higher level than EDTA/DPTA and EDTA/DPTA can be more than simple mineral)
- Mn (Manganese): 0.06 to 0.15ppm
- Zn: 0.025 to 0.06
- B: 0.01 to 0.3ppm
- Sr: 1% of Ca
- Mo: 0.002 to 0.01ppm
- Cl: 0.002 to 0.01ppm
- Co: 0.0005 to 0.001ppm
- Ascorbate: 5 to 10ppm
- Se: 0.0001 to 0.0005ppm (Beware: Highly toxic at high level)
- Na: As little as possible
