Never have to change your water again...

I'm not sure what category this should go in, but I figured this is a safe guess. Move it if it's in the wrong spot, please. Anyway...I was told that with a saltwater setup, you never have to change the water. I was told the water goes through an extensive filtration system then back into the tank(I know nothing about saltwater...this is only what I was told). Is there a way that anyone knows of to do this with a freshwater setup? If so, how do I do it? If not, then could it maybe be possible(with a bunch of inventive minds on a forum thread)?

that is not true for either kinds of tanks. saltwater or fresh. you have to change water at some point.

I change the water in my FW tanks maybe twice a month. I have to change the water in my SW tank once a week!

In a low bioload saltwater tank with lots of live rock, it is possible. However, you need to supplement trace, and top-off water. The live rock not only breaks down ammonia all the way to nitrates, the many anerobic pockets break down nitrates into free nitrogen, which escapes the tank. My LFS has a salt water tank (actually the Live rock holding tank) that has not had a water change in over a year (supposedly). It's on a seperate filtration system than the rest of the tanks, with a sump filled with live rock rubble.

EDIT: An interesting idea for freshwater though. What if the intake rate of the plants was found and the dosing set to match it (and adjusted periodically) to maintain proper nutrient levels? Water coming in from water changes contains what? gH, kH, trace, ??? which can all be supplemented. After all, we need to ADD all that stuff to keep it from running out in a heavily planted high growth tank. Hmmmmm

So I assume it's not possible to make a setup that only requires a top off for freshwater tanks? I have to change my water once a week and my nitrates are still always high.

If you frequent various fish forums, you would come to realize that folks posting on fish forums enjoy changing water.

Changing water on a 10g is kinda fun. Doing a 50% water change in a 180g is another story

Let's put it this way, there are thousands of threads on this forum. How many of them are about minimizing water changes? Even suggestions about doing infrequent wc will normally be frown upon.

at some point you will have to change the water in any kind of fish tank. there are other chemicals in the water that will harm the fish other than ammonia, nitrites and high nitrates. some fish release hormones that are harmful to themselves. like juvenile discus for example. they need frequent water changes because when they are young, they release alot of hormones that can stunt their growth.

w/c's even in the biggest tanks can be fun as long as you're smart enough to use a PYTHON!!! Anyone still using the bucket is in the dark ages. (unless of course it's a 10g)

I use a Python for my 10g. =P Of course I have 6 other tanks to WC at the same time.

I recently ruined the threads on the stupid green thing for my Python. Yech.

I've heard a lot about this "python"...what is it and where do I get one? I use a cup and my sink for water changes . I also tend to my plants when there's about half the usual amount of water in the tank because I use regular scissors. Is there something easier than reaching into the water? Sorry for being clueless, but I'm really new to plants....especially planted tanks!

It's at PetSmart too. Print out a copy of the PetSmart price and bring it in to price match.
