Rodi winter question

[Fishingandreefing]

I just want to document this and possible helping others. I just tested it and it takes about 10mins per gallon so technically I only need to flush 5 hours of the RO membrane (30g). I will then test to confirm it’s less than 2-3 tds.

Based on my calculation it’s now close to 6 hours which mean it’s at least 35g of RO water was flushed. However, it’s still giving me the reading of around 7 tds.

both sediment and carbon filters are brand just replaced today prior to the flush and it was flushed till clear.

not sure if this will even go down to 2-3 tds
