transporting established tank help please

It is your evidence, the burden of proving it is on you. If it's in a middle school textbook, you should be able to easily find it online and give me a link.

See, if I tell you I have a million gallon fish tank, and you say you don't believe me...is it up to you to prove I don't?

And you're still not answering my question...why isn't it common advice then?



Really? So you're saying that it's not "needed"? Why not, it would be fantastically beneficial for your fish. Fish grow much better in water with virtually no No3

I put up a poll in the set up and filtration to see who has done large or who does frequent large water changes so there is no more useless arguing.

I really don't understand the flooding argument, it's not a 100% water change, the fish still have the water from the river that they were in. Also there is alot of fish that die after tank transfers because of the difference in water. I thought this was pretty common knowledge.

I'll help out with your evidence; rain water has a low Ph base most of the time. Very acidic rain caused by pollutants can cause a sudden, but minor ph shift down in a river without buffer. Prolonged acidic rain causes significant shifts in water chemistry. It does not change particularly quickly, and if it does, fish DIE.

The most obvious environmental effect of acid rain has been the loss of fish in acid sensitive lakes and streams. Many species of fish are not able to survive in acidic water. Acid rain affects lakes and streams in two ways: chronic and episodic. Chronic, or long-term acidification results form years of acidic rainfall. It reduces the alkalinity (buffering capacity) and increases the acidity of the water. Chronic acidification may reduce the levels of nutrients such as calcium, which, over time, may weaken the fish and other plants and animals in an aquatic ecosystem. Episodic acidification is a sudden jump in the acidity of the water. This can result from a heavy rainstorm. It also happens in the spring, because the sulfates and nitrates will concentrate in the lowest layers of a snowpack. In the spring, when that snow melts, it will be more acidic than normal. Episodic acidification can cause sudden shifts in water chemistry. This may lead to high concentrations of substances such as aluminum, which may be toxic to fish.

So, given your total lack of ability to find any evidence to support your position, you have decided to post a flawed poll based on public opinion?

Your poll is wrong. A better one would be..."Who feels that doing 99% water changes is good for your fish?" or something similar.

what a bs poll he setup LOL

Ok Simon you just admitted that there are water chemistry changes during rain.

Large water changes make for disgruntled fishes. I went from a 20, to a 30, to a 60; all three times I had to add approx. 75% new water to the old. Talk about some pissed off looking fish..They were seriously stressed. I can't imagine doing that to them more than I have to.

PWC's are a much safer bet, as the waters more stabilized, and they're used to it.

Of course there are in certain cases.

Your argument was that because the ph in rivers change "all the time", that it is fine for your aquarium. Here is your quote;

You do realize that when rivers flood the ph and tempm and hardness all change right?

If you actually bothered to look into the issue, you would see that even when these changes occur, fish DIE. Besides, you were asserting that water ph apparently goes up, like it would when you're changing 100%. Find me some evidence of a quick and harmless ph increase.

obviously it changes a little bit, but not even close to the degree of a 100% water change. no matter what a water change will affect the chemistry. what you are trying to avoid is a DRAMATIC change in water chemistry.
