Nutrients in the water

[King Midas]

Ive been told that fish use up all the nutrients in the water in 72hrs. Well how do the nutrients get there in the first place? Roting fish and plant life, right? Isn't it good to bury a fish head (fish remains) with a seed to give the seed nutrients to grow? Basically I'm trying to find out if theirs any way to put nutrients back in the water. Could you put vegetables in the water and let them sit for a couple of days, or is their any plant nutrients you could safely add to the water, or am I just crazy? I know this sounds stupid, but I wanted to see what everyone thought. So, go ahead, let me have it.

The only thing fish get out of the water is O2...Thats of course an oversimplifycation but for all practile purpases it's true. Anything decomposing in the water provides nutriants for the differant forms of benificial bacteria but your fish will provide everything they need without you adding anything at all.

What you might be misinterperiting is the fact that live corals in a reef system DO pull nuteriants as well as trace elements out of the water. This is one the things that makes a reef tank a cut above your average aquarium. This has to be replaced either by dosing or frequant water changes.

Fresh water tanks on the other hand....except for a few rather rare cases don't need anything more than warm...clean...water with the proper PH. Well food of course...LOL

Well said Wolf...I think that just about sums it up.

To go along with what Wolf mentioned, that's the exact reason why I run dosers and drip systems on my saltwater setups...due to the nutrient drain from any sort of inverts.

LPS and SPS corals are very dependant on what is "free floating" in the aquarium. These stony corals will drain every last bit of calcium out of the system in oder to expand their colonies. People will often add calcium reactors or kalkwasser drippers to the system to supply a constant amount to the system and ensure proper growth.
