Hey guys, just new to the site and the hobby and I have a few questions. I have a friend that has a Salt Water sytem going, rather, half going. He started the system up about 8 months ago and it was doing awesome. He moved away and left his brother in charge of the tank. The brother did not look after it. It is stocked with live rock and at least two inches of live sand on the bottom. He has a very powerful protein skimmer and powerhead but due to the lack of maintnance, both have quit working and I am not even sure how long they have been off for. He does however still have a large canister filter with the output going directly into a uv
sterilizer so there is very little filtration/water movement going on, but still some. The tank obviously has not had any water changes in at least a few months and there is quite a bit of detriment on the live rock. The heater has kept the water at a consistent 78 degrees. I guess my biggest question is about the live rock and live sand. Is any of it going to be salvageable if I take the right steps to clean it up? Or would I just be wasting my time because it will all be "dead". I have already given him the money for the entire system so I am just wondering if it will be a waste of time with the live rock/sand, should I just throw it out and get new stuff that has not been put through so much "torture". I appreciate all the advice in advance and look forward to being a regular contributor to this forum.
