RO system for PRL

[ryangiggs]

Is there any recommended RO system for keeping PRL and fire red?

Currently my TDS is 140 and PH ard 6.4... notice that breeding is slow and shrimplets survival rates are low...

thought maybe using RO water might be better and re-mineralised it might help...

Is Xiaomi Water Purifier enough to do the job? Looks neat...

preferably those with less water wastage... and easy to setup...

Forget about xiaomi water purifier. That for pure drinking purposes.
Get the decent 5 stage RO and DI water unit. For PRL wise, definitely you need RO water.
Alternatively, use distilled water (ntuc brand) or other budget type.
But in long run, RO water unit is better.
