Sorry to hear that.
It can be a beast to conquer the marine aquarium, and work wonderfully too, but when it doesn't it can drag you down (I have first hand experience which is why I left mine fallow for over 10 years, prompting the Doris to plead with me to take it off the wall, after all, a 5 1/2 foot aquarium with just rocks in it and no lighting is an eyesore)
I just rejuvenated it out of bloody mindedness. It was make or break for me, and I'm getting better but not out of the woods.
I fully empathise.
