the stages are thus;

100 gallon per day membrane
5 micron sediment pre-filter
1 solid carbon block filter
1 GAC coconut carbon filter
1 inline carbon filter
1 inline DI filter
pressure= ?

tap = 211ppm
RO = 011ppm

I have KENT 10gpd barebone system: prefilter with carbon and sediment
filter, after TFC membrane I have KENT DI stage with mixed bed resin.
After membrane I read 5-6ppm, after DI stage, when water is dripping
from the pipe it is 0-1ppm. When the water collects in the bucket and
equilibrate with the air (mostly CO2) it could have high tds readings.
CO2 dissolved in water could decrease water resistance measured with
TDS meter increasing readings.

i thought that i could put up with a slow production but not poor water
quality, especially with the money spent. surely 11ppm is a lot better for
my reef than 210ppm. i did have a tapwater purifier but i'm not sure of
it's quality. i'd be a bit peeved if it's better.

Check directly water dripping from the product line.
In your case, it will not drip but flow rapidly, I guess ;-)
