These guys were servicing my 200 gallon saltwater tank. Everything was going just fine for months but then the tank started to have problems. I expressed my concern over a 3 month period because my coral was starting to die and I had massive algae growing. No proactive consultation on their part in spite of my pleas that something is wrong with the tank. After having someone else come in for a second opinion, I found out that they weren't even serving the tank properly. I'm guessing if I replaced all of the coral that has died, it would cost more than a $1,000.
