Too many water changes? Is it possible?

[BillD]

A 10% daily change is not the same as 1 weekly 70% change, actually, not even close. When I was raising angel fry, I did no less than 60% daily.
How do you reduce nitrates "too much"?

 

[Miguel]

10% daily W/C is, IMO, much better than one weekly 70% W/C. Fact being that a drastic change in almost any type of parameter can have an adverse affect on your fish.

Of course!

what about the fact that tap water contains things like chlorine, and floride?

what about places where water is hard or not perfect for fish perams?

i think all these things needs to be considered.

and don't forget the temp difference. is your tap water colder/ hotter than whats in the tank?

your temp drasticly drops a couple degrees cause of rapid water lost replaced by colder tap water? now think how the fish would feel.

and also how come no one asked how big the tank was?

Mmmmm.... because

...The tank is a 135 gallon...

I agree with the temp. change thing and think that small changes are probably better, but more like every 2nd day, not every day. I think the new water needs a chance to mix with the existing and good/bad stuff get all swooshed together. Just my scientific/technical input!

Bulk water changes are always going to be stressful for your fish. The larger the percentage changed the greater the potential for changes in the fishes environment. Even if you have accurately managed PH, hardness and temperature you’re still likely to be changing the osmotic environment pretty sharply.
Particularly if y’r using a Python where you poor chlorinated water directly into your tank and rely on mixing this with all the water conditioner you added in advance.
Always best to keep ‘em as small and frequent as possible.

I really don't think you can change to much water, although there should be little or no varience in pH and temperature.

Mmmmm.... because

LMAO
In regards to water hardness chlorine etc...
I live in Florida, no flouride. As far as chlorine is concerned, I use a water conditioner that removes chlorines, chloramines, heavy metals etc. As far as hardness, PH etc I do not adjust the water whatsoever. It comes out of the tap at 7.3 and that is fine for the fish I keep. I've never even tested the hardness levels but I have healthy fish so I guess it's good. As far as temperature goes, I live in Florida lol. Water comes out of the tap at 78 degrees and if it doesn't I just turn the hot water lever a little bit LOL.

also how come no one asked how big the tank was?

because he told us in the first post 135 gal


but for my .02 I do 50% weekly on my 130

Okay this large water change/small water change comes up way too often.

Gotta get on my soap box - get ready....

Okay seriously - large water changes stress fish? what's stressful about clean water?

Large water changes will damage the biofilter? Okay my canister filters never dry out even if I change 100% of my water...so someone really must explain why large water changes "mini-cycle" tanks.

If you can't guess I do REALLY LARGE REALLY FREQUENT water changes, and my fish are freaking happy.
