Does anyone know if most HMA units come with the cartidges, i assume they do?
I have seen a 3-stage HMA unit from Devotely Discus for £75 and it reckons it treats 20,000 gallons of tap-water, which going by water changes would last me 3-years! Can they really eb this economical?
the replacement cartridges for the unit are £31.48
On Plymouth Discus the 3-stage unit is £89 and replacement cartridge pack is £39.99
Are we talking about spending £75 to £89 here and then being able to filter up to 20,000 gallons for water changes? If so, i think i like this.
