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 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.

I did not notice you have a DI stage from your previous message. You should
be getting close to non-detetable or close to zero from DI output. What
micron size on your 2 carbon block?
