Aquaticlife 100GPD question

[Fishingandreefing]

So is that mean it suppose to makw 100g of rodi in 24 hours within the recommended psi?

I roughly make about 50g of rodi a week.

Based on this rate, roughly how long do i nwed to replace the membrane?

I changed out all the filters except the membran being 10 months old and it takes about 1 hour 20 mins to male 5g.

Any advice?

The membrane lasts as long as the rejection rate is above 95%.

It's my understanding that best practice is to replace the rodi membrane annually.

Yes 100 gpd = 100 gallons per day under correct conditions

So if my math is right. 24 hours divided by 100 = 24 mins per gallon.

So for a 5g bucket, takes 1 hour and 20 mins, I am right on the money then.

annual replacement seems about right for me, it’s around $50 so.

Around 92%. So is that recommend or a must to change kind of thing?
