brandon, I was that way at one point this year. I actually had my 75 up for sale. I had conquered it. it has been running for close to 9 years and for the last 3, it was awesome. needless to say it didn't sell. i have no room for any new corals.
now, im trying new things. working on keeping anthias. so far, not much success, but getting there. about my tank:
1. no water changes
2. no dosing
3. no regular maintenence except scrubbing the glass and cleaning the pumps.
4. I dont do squat to my tank. it is truly just another piece of furniture, but I love it.
my best advice is to strive for new things. different corals, new fish types. go for the moon with things and see what you can do. for me it is now the anthias. im working on the purple queens. so far out of 3, I have one that is active and seems to be doing well, just never seen it gorge like the other fish. if it dont make it, we are looking and trying another type.
hang in there bro. i am so glad my tank didnt sell. it is awesome when folks come over and are "wowed" by the little piece of reef I have.
