water changer...how to set up with AC3 ATO? (1 Viewer)

[noeldokken]

I had just installed my two way water changer system, a litermeter III, with remote pump module. I have a 30 gallon tank (didn't feel like waiting for an acrylic so just got a glass) that I am using as my saltwater reservoir (need to get a glass or acrylic top to prevent evaporation).

Currently my AC3 program is this for the top off of freshwater.

OSC 010/050 ON/OFF Then H20 ON
If SwitchA3 CLOSED Then H20 OFF
If SwitchA3 OPEN Then LOW ON // my Dummy Timer so I know when switch is open or closed

If SwitchA3 CLOSED Then LOW OFF
If pH > 08.60 Then H20 OFF

However, with the litermeter I am going to have it replace about a gallon of water per day (should yield just over 10% water change by volume over a 7 day period).

My LM3 is connected to my AC3 (I feel I have more control via this way), but how do I prevent the ATO from going on when the LM3 is taking out 100ml of water at a time?

Would it be beneficial for me to estimate over a 12 hr period how much the LM3 would take out, then have the AC3 turn it off and then switch over to account for the evaporated water?

What would you guys do?

SwitchA3 is a float sensor?
H20 is a pump?
What is the connection between the LM3 and the AC3? I'm not up to date on the litermeter.

Why can't you just turn off 'H20' when LM3 is on?

I have a px1000---hence the "Switch A3". H20 is the dosing pump supplying fresh water through my kalk stirrer. I should have clarified that. When the Switch is OPen, meaning low water, the AC3 turns on the "h20" or BRS 50 ml/min dosing pump.

The only connection between the LM3 and the AC3 is to give me more control with my Reef--really.

I thought about that too "turnning off H20 when LM3 is on"...I guess I never said that I couldn't do that in my post, but apparently I did.

I know I'm not the only one that is using the LM3 as a two way water changer, so I was just asking what the best set up was in conjunction with my ATO top off that is controlled by my AC3....
