First off Congrats on the engagement!
Next I like the layout of the 55g! LOVE the GBR!!! They will be going in my 55g too! Probably within a month, so I will be checking to see if Matt has any then!
BE CAREFUL raising the temp! Do it SLOWLY!!! No reason to feel like a dumba$$, things happen, and usually do when we are out of town!!! I would let it take at least 24hrs to get to the temp you are usually at. I didn't see it posted anywhere, and if it is and I missed then sorry, but what temp do you usually keep the tank?
It seems like my CO2 tank (5#) knows when I have to go play Cowboy at the family farm when my Parents are going out of town, because it always runs out when I am gone! I ALWAYS check it before I leave, but after a few days of being gone my wife will tell me the drop checkers are blue not green when we talk at night! GRRRRR It ALWAYS HAPPENS! I don't want her to have to change out the tank either, because my cerges reactor is a PAIN to deal with, how I have it plumbed in at the moment! So my plants suffer for a few days to a week or two sometimes, then the DA^N algae takes off! So usually about the time I get it all right again, I have to go Farm Sit!
ANYHOO Let us know how the Rams do after getting back to regular temp! And be sure to watch them close for a week or so for signs of ICH due to the temp drop!
Keep up the GREAT WORK on the 55g!
