carbondoser

Up for sale is carbon doser,asking 150$ pickup in Edison NJ 08820.

I have an old CarbonDoser v.1.0. I noticed that the low pressure gauge varies during the day. For instance, if I set it to 8 psi at 8:00AM and I look again at 8:00PM it may be at 7.5. psi. Is that normal? The pH in the Calcium Reactor is varying accordingly to this variation, so it seems it...

Looking for a CarbonDoser for my calcium reactor setup.

It's a long shot but I'm looking for a carbondoser with push connect fitting in good to excellent condition. The R2R members are too quick for me to buy off the forsale forums ;Sorry

I have a 2 yr old Carbon Doser. Little corrosion around the gauges and fittings and led is a little dim but still works great. Comes with a new co2 hose. $200 shipped within the USA.
