How much water should i change a week for my 140L?

I was doing 50% w/c on my old 60L, but the amount of water in the new tank that would need to be change if it was at 50% would be 70L ! that alot of bucket trips!!!! :roll:

So because its a larger tank does that mean less water needs to be changed?

What fish do you have in there?

uhhh..

:roll:

-20 neons

-6 Coolies

-3 platys + 15 ish fry (* want to sell off)

-3 guppies

:lol: :lol:

I would still reccomend at least 30% weekly.

Mmk.

I had an idea about changing the water faster.

I think ill just A hose from miter 10 and run it from my tank though the house into the garden. Then plug it into the wash house tap ( which can run hot water) to fill it back up . :lol:

Have you tired those tap connector things on trademe? Thry pretty much do exactly what my hose would do ...

yes///30% water change weekly..

Buckets? Who uses buckets?

I do 50% monthly on my 150L.

I test weekly though and do a change if anything is out of the ordinary.

I do 100 litres every second day 50% (10 buckets ) on my discus tank and once a week 80%

With the type of fish you have you should only need to do 25% - 30% a week

Will post a pik of the Hose attachment my Hubby made for me, makes water changes so much easier.

I was going to do a whole Thread on it, but just haven't got round to it.

This is the end that attaches onto the Kitchen Tap

This is the end that I hook over the Fish Tank to refill it

Think I will do a new Thread on this

Yeah that's my thinking, too. You don't have a lot of fish in the tank, and they aren't particularly big or messy. What kind of filter do you have? A good filter with decent flow and a reasonably large volume of good filter media would be an advantage - but I really think you probably only need to do 20 - 25% water change weekly.

I have one of those blue planet tanks, it has a built-in filter - 1400 Lph flow rate?

I have one of the tap connectors - You need the metal thread. I am now on my second tap connector as the first one snapped but it wasn't new when I got it. Works well.
