Actually, just trying to add minerals back into the constant drip as I only have access to softened (Kinetico water softener) well water. Since I'll be introducing softened water at 1 gallon per hour, there's no way for me to keep up using Seachem Equilibrium like I do with all my other tanks. I'm just having a hard time finding a 3 stage assembly for carbon, sediment, and remineralizarion 10 inch filters that actually have 3 gauges.
