Hi everyone. I'm from the UK and have done quite a lot of research using this forum recently before buying my first saltwater tank. I've searched the Web to see if I have a problem with my tank but can't really find an answer. I have bought a used red sea max nano. I noticed when cleaning it out before use that the outlet nozzle wasn't sealed between the display and the rear sump (I may have made it come loose) When filling the display the sump started filling up in the return chamber through the outside of the return nozzle. I wasn't sure if this was a problem at the time as I've never had a sump on a tank before. After running for a couple of days I stated to hear water trickling into the filter sock and the salinity level has increased slightly indicating a lower water level. From what I have read the return chamber level will drop when water evaporates and the built in ato should fill it back up but the water level is the same in both parts of the sump and the ato still full. Is the display tank filling the sump so the ato isn't working or would the return pump, pump fast enough for that not to matter? I'm thinking I'm going to have to drain it and seal the outlet. Sorry for the long first post and thanks in advance if anyone can offer any advice.
