Here it is.
So, with these 2 links, you will have replacement sediment and carbon blocks, and replacement resin - plus an extra replacement for the carbon block filter.
For TDS meter, BRS sells an in line one that has murlok fittings. Looks like it would work on your system? Definitely need one as this is how you can tell when it is time to replace the filters. I recommend testing both TDS on out of the membrane and out of the DI resin.

You should look at their carbon reactors though. They are great and not too expensive.

Also, a good comparison video between the different grades:

While bituminous doesn't perform as well as some of the higher grades, I think running Rox 0.8 would be tough in a bag because the particle size is so small, and I think the lignite would turn to dust in that environment (based on my experience with lignite through my work).
fort384 said:I am not so sure running carbon will help that. It is more about polishing the water than reducing organic nutrients. Do you know your PO4 level?
fort384 said:Well you can run gfo in a bag to reduce phosphate. That and nitrate are the biggest nutrient contributors to nuisance algae.
fort384 said:I would test PO4 first just so you know. Low trates does not necessarily mean you don't have nitrate issues either - the algae could just be using it all up so it tests low.
