Man I can't believe the frustration of going threw that ordeal! I had a 200 gallon marine land deep dimension and ended up selling it and downgraded but a 300?? Wow.... You must have had a slopping mess across all your ground floors and even any leaking into the basement if you have one! What a mess! I had a few sump mishaps but not an entire tank drain! Ugh! I def would have considered doing the sell it all and get out of it but then again I have been doing this hobby for along time as well! Everything looks marvelous! Livestock and even tank stand and all looks awesome! Having that low level sump looks much cleaner and easier to work around! Nice job! Cheers!
