Looking for an RO unit

[BII]

Regarding my noting that, "Chloramine is presumably a strongly charged and reactive salt, easIer for the RO and DI filters to remove:" Upon further looking, this is correct, yes it is easy for DI (activated carbon/charcoal) filters to remove, but chloramines in tap water can quickly clog, fill all the binding sites of standard filters. The chloramine-specific filters simply contain more activated carbon - either more active/concentrated or more packed into the filter, so they last significantly longer.

Ever think of using Rain water? just run it through a cheap charcoal filter to get the car exhaust out of it. Been using nothing but rain water for years, cheap and effective. A tip use bone char {google it} as the filter medium, clears the heavy metals and adds phosphorus. If you grow in soil, IE living soil as I do Bone char is great platfrom mycorrhizae to colonize { think Bio char }

Quick googled search on bone char in cannabis soil;
Key quote from AI:

Here's how bone char can positively impact cannabis growth:

• Slow-release phosphorus: Bone char is a rich source of phosphorus and calcium, providing a slow and steady release of these nutrients to plants over time.
• Enhanced growth and yield: Studies have shown that bone char applications can significantly enhance cannabis growth, including increased plant height, biomass, and cannabinoid content.
• Improved soil structure: The porous structure of bone char improves soil aeration and water retention, creating a more favorable environment for root development.
• Reduced heavy metal uptake: Bone char has demonstrated effectiveness in reducing the bioavailability and uptake of potentially toxic elements like lead and cadmium by plants grown in contaminated soils.

Sorry off topic, need to put the spilf down....
