I'm helping a friend who recently bought a house with a 240gal inwall tank, upgrade it.
They have a maintenance guy who works at a lfs
and cleans the glass & does water changes. Last week we drained the tank, added a sump and overflow, and called the maintenance guy to fill the tank back up.
The maintenance guy literally took the hose from outside and filled up the tank and then mixed in the saltwater. I was not there to see this, but I would have stopped it if I saw it. What is this going to do to the tank? Is there anything I should do besides a lot of PWC
's? Please help! TIA.
