Hello everyone and greetings from Aus,
I need help please!
I am new to having a tank with a sump.
I have a cade with a gravity fed ATO sitting behind the DT.
Yesterday I did the first water change after the cycle has completed. I made marks on the sump for running levels and shut down level.
I made an error in using a different bucket for calculating exported water to the bucket i used to refill, which resulted in a low level in the return pump well (where the ato float sits). I added more water to the return well.
This morning i have woken to "brook like" sounds and discovered the ato float totally out of water ( with only drips falling) and the ATO behind the DT has filled with water to the same level as the DT.
I touched the float and now the level in the ATO is lowering.
Did I put too much water back into the system?
How did the back syphoning occur and how do I stop it from happening again?
Thank you,
Simone
