Tom:

Thanks for the advice, I know I'll be happier with the OC, but I wanted to stay with one brand this time, so that it look consistent. That and I thought it would be easier to change to Pentair filter vs the OC. With the pentair, I just slide out the filter, put a bucket underneath, remove the cap and replace the filter.

Steve:

1) Move your drain solenoid to a spot downstream of you mech filters. That way you have no change of them getting gummed up with crap from the tank.

I wanted to have as much flow as I can, because I plan to water my garden (using the spinning sprinker thing). But having the solenoid fail due to gunk is worst. I'll make the modification.

2) I LOVE the parallel flows, but I'd move one UV and one heater to each of the twp parallels. That way you can take one of the two paths down and still have heat and UV covered. That will, of course, mean a new bypass on the lower path.

The reason I have them the way they are because I thought for UV to be most effective, contact time is the key. By having the UV in series I double the contact time. Heaters is probaly the same? I can heat the water more effectively if the heaters module are in series.

3) Move your temp and ph probes before the two paths diverge, i.e, before the "T" to the mechs. That way if either path is taken out, you do not lose those two VERY critical functions. And obviously you can't move them to your retun manifold because your temp and pH won't reflect what's in the tank.

I just afraid a plant piece or something can catch on the probe and cause it to give a false reading. Can any plant make it through the propeller in one piece?

4) To Tom's point, you might consider replacing those horizontal Mechs and Chem with something that is not going to pour water everywhere when you open them up. The heaters and UV are not as important, as opening them is not too often. But the mechs and chem will have to be opened with some frequency, and it's gonna be a pita. IMO leave them where they are in the loop, just use vertical rather than horizontal canisters.

As mentioned previously, I'll have these modules on a slideable platform, that way I could move them out (6" or so) and change the filter without wetting the stand.

I guess the issue is I'm not sure how easy it is to change the filter media on the OC. My stand is pretty short, I just afraid I don't have enough vertical space.

Thanks again for all the input.
Khoi.
