They run from $145 to $300 depending on what options you want it do. True professional grade TDS meters made for commercial R/O units. A little expensive but light years better than those small battery powered ones. And they're small too. Only 3" X 3" and 4" deep

|Legot||Wow! Those controllers are nowhere near as expensive as I thought they would be!|

Next on the list - automated water mixing for w/c reservoir.
I have well water so chlorines and chloromines are not an issue, but .... the water coming out of my well is like liquid rock, high in magnesium and calcium and insanely high iron levels. I've got to reduce this not so much for the fish, but to keep the hard water stains in check over time.
Use a mix of mostly R/O water with just enough carbon filter only well water to re-mineralize it.
The problem with this is consistency and automation which is critical for me.
So after some searching around I found this neat gizmo. A TDS monitor and controller.
What it allows you to do is set a high and low set point for the TDS and it will activate relays accordingly.
1. I will have an overflow drain built into my water reservoir so any extra water added will just run off and no chance of flooding
2. R/O and straight well water will fill the reservoir at different flow rates to get the proper TDS close (this will take some experimenting)
3. The TDS controller will have it's sensor on a circulation pump in the reservoir
4. As the TDS controller reads the TDS it will open valves on separate water feed lines to the R/O or straight well water. If the TDS is too low it will add non-R/O water until TDS comes up to set point and add R/O only water if TDS is too high. All excess will just go down the over flow drain.
1st stg: 5 mic sediment filter
2nd stg: brim filled 20" big water filter housing - this will be plumbed up with a series of 3 way valves so it can be backwashed
3rd stg: another sediment filter (brim is a catalyst that precipitates out magnesium and iron, most will be trapped in the brim media, but some will pass through and need caught)
4th stg: mini-water softner made to fit in low cabinets for restaurant dishwashers
5th stg: 5 mic carbon block
6th stg: 0.5 mic carbon block
7th stg: 75gpd R/O membranes x2 with booster pump if needed (150gpd for a 300 gallon aquarium)
The brim filter and water softner should greatly extend membrane life
The "tap water" for mixing with R/O will be pulled off between stage 1 and 2 and then run through it's own series of carbon blocks

Got my venturi injector for the Co2 system today. Very nice piece made by Mazzei.
I have also figured out how to make the Apex controller work with the Pentair pump. I cant directly control pump speed, but I will be able to switch between the 4 programmable preset speeds using the Apex.

It will literally take 3-4 days to fill
