View Full Version : Please tell me if I have enough parts for an ATO and an automated water change...

Here are the pieces I have currently:

1. Spectrapure ATO (LLC-UPLC-ATO)

Here are the pieces I will have in a week or so:
2. LiterMeter 3 (Gen 6, around 6 months old)
3. Two remote pump modules (LiterMeter® III Remote Pump Module - LM3-RPM)

Is there any way I can have all these connected to perform ATO and automated water change duties? Or, will I have to buy the WXM? Thank you.

I read some old posts and please let me know if I am doing this correctly.

It looks like I need to order the TCM for additional security, just in case the water level gets to high in the sump. I can use the built in pump on the LiterMeter to pull water out and use one of the RPM's to put saltwater back in. Does this sound correct? I will not connect the UPLC-ATO to the LiterMeter and leave it as a stand alone ATO unit.

Everything about your last post is correct.
