Quick question on some old stuff..... Why 1- 3/4" and rest 1/2" Is the 3/4" for the biopellets? Would all 1/2 have sufficed? Or would all 3/4" been better?
Thanks again...
Oh and what valves did you use for the other ball vales on the return pump? Savko as well? Do they turn fairly smooth?
Yes, the 3/4" valve is for the ecoBAK reactor. The SMR1 reactor has 5/8" fittings so I didn't want to restrict with a 1/2" ball valve so I up-sized to 3/4". The main valves on the system (not manifold) are Chemtrol made by Nibco. They are Sched 80 industrial grade valves made for commercial applications. I actually bought them from a friend who works at a local water company. Don't know if you can find them online or not but BRS has some nice looking valves. Other than that you can't go wrong with Georg Fischer valves. They are very nice.

You have the regular smr1 correct? All my valves on my manifold are 1/2". I was thinking of getting 1 pellet reactor and one regular smr1 for running carbon.
Yes, I have 1x SMR1 and 2x MR1. Sounds like a good plan. I would get an SMR1 for the pellets and a MR1 for the carbon. The MR1 is basically the same size but has sponges for loose medias like carbon and gfo. The SMR1 has a perforated plenum for bio pellet use. You can probably find a 5/8" x 1/2" adapter to fit your plumbing with the SMR1. The MR1's have 1/2" so they should work out of the box.

Hi DR,
I'm new to the 2-part dosing concept and have read the articles from R.H.F.... What will you automatically dose in your new build? Dosing pumps only or other Drip methods?
Great! 2-part is an easy DIY method, I've found it to be very effective over the last few years. Currently I'm manually dosing, so just pouring each part (separately) into a measured cup and then dosing into the sump. As the demand grows I will either incorporate a dosing pump to automate the system or just go to a calcium reactor. It will be some time before the demand is large enough to justify a Ca reactor so I'll continue dosing 2-part until I see the need.
