I am out of my job come tomorrow but I have budgeted myself for the next couple of months for the tank. I will be ordering a new 400w bulb and replacement cartridges for the ro/di. Including these items I have $600 to spend at the moment. I have plenty of food and new test kits. I was thinking about adding another pump and sea swirl but I am thinking about just keeping it going at this time. Don't want to miss anything important.
