I'd like to ask you guys what your tank tds is. and some relevant factors.
1. How often do you change water and percent.
2. What is your dosing regime (ppm numbers per week)
3. What is your target calcium and magnesium levels.
4. What is your tap water tds (or just say you use RO if you do.)
5. How much does TDS rise throughout the week.
6. If you do use remineralised water have you tested the tds of the water with zero ferts and only calcium and magnesium.
7. what tds scale does your meter use
8. and lastly what is the tanks tds.
additional info:
my details.
1. once every two weeks, 50%
2. 8ppm No3 (urea), 0.8ppm Po4, 1.5ppm K+traces,
3. 18ppm Ca, 6ppm Mg.
4. RO
5. very little tds rise usually. maybe 2-5 ppm in two weeks. with heavy plant growth, tds can go down.
6. remineraliser water only is 65-70ppm TDS
7. TDS-500
8. tds is 85ppm.
additional info: tank has new soil which is raising TDS a bit.
cheers.
