water changes?

[tntechworker]

How major an issue would it be for someone to go 6 weeks with out doing a water change on a tank with several fish in it?

FOWLR would probably be ok depending on the sensitivity of the fish, and how over-fed they get (bioload). This does't mean it's a healthy practice to do on a regular basis.

id like to hear from as many people as i can on this even if you agree with what has already been said and by the way the tank in question has an anemone and some crabs and snails

FO probably not a big deal just keep an eye on your nitrates.

 

[tntechworker]

at what nitrate level should i do a change?

Thats a good question question which sorry I cant answer my reef is always at or near 0 on my test kit and thats whre I keep it.

i heard someone comment on here he only did a water change twice a year. from my understanding the waterchanges mostly benefits the corals. if you have a fish only tank and the levels are always at 0 then what will a water change benefit anyways. i do mine weekly a 5% only because its a reef tank

FO - nitrate can probably go as high as 60 - 80 ppm? Cut back on feeding, the water might be OK for 6 weeks.

As close to zero as possible, reef tanks still require some nitrates. If I had to put a number on it I would say no more than 5ppm.
