Hi all,
I know this subject has been discussed on numerous times, but I would like to hear your opinions.
My current setup is a 350l long planted tank and I'm doing a 80-100l/week water change.
The tank is fed by a 4 stage mains filtration system composed of 1 micron sediment filter , followed by 2nd and 3rd stage of 1 micron Pentek Chlorplus and the 4th stage is a 0.5micron Pentek carbon block.
Incoming TDS on the mains water (before filters) is varies from 70 to 90ppm.
Because my Silica levels on the tap water are measured to about 6ppm and ongoing battle with Diatoms, I was thinking to add a RO/DI to the existing filtration system.
Ideally I was looking to get 2 300gpd RO membranes in series with a 600gpd pump, followed by a DI stage .
This way I can do a water change in about 2 hours. (ideally). Don' have the necessary space for the water storage.
Any recommendations for suppliers / membrane brands ?
I was looking at:

https://www.osmotics.co.uk/300-gpd-reverse-osmosis-membrane.html --- Chinese brand/made
