The Ph Of Rainwater - There Goes Another Theory!...

[Ludwig Venter]

Unless there is something wrong with my digital pH meter...... I've just eliminated another theory I had about rainwater.....I cannot say where I heard it, but I've always been of the opinion that pure rainwater weighs in at just above 6.5 (or less)....

Well... we've had rain all day (so far) and I've got drums below every downpipe and must've collected about 4,000 liters already. I just measured the pH in one of the drums and it comes in at 7.6......

Can anyone please confirm to me that that is possible.....

And then also...... How do I apply 4,000 liters of pure rainwater to justify my efforts to collect it.....

Well, when you think about it... there could be something else in the barrels that is making the water go alkaline... try leaving a clean glass out in the rain and then testing...

on the car/garden/windows... you could use it for the tanks (but i think rainwater is subject to PH crashes though (correct me if i'm wrong)) heck, you could even take a bath in the stuff if you have tuhat much! i know what i would do with 4000 litres of water lol!

the acidity of the rain water depends on where you live, i.e. if you live in the middle of no where where the winds and rain are coming from over sea then the rain i would expect be normal what ever that is but if your down wind to a factory or something pumping impurities into the atmosphere then the rain will be more acidic

i think, and i emphasise the THINK you can put rain water into your fish tank, in theory it should also be chlorine free but don't count me on that, if its okay for the fish i think i shall do the same one day it rains so much here

yep, you can put it in a tank OK... lakes and rivers have rtainwater in them dont they!!!

I just think it will take a lot longer to cycle pure rain water, but my thinking was that once done..... I'll be able to spawn neon tetras in there...... but deffo not at a pH of 7.6.....

thats for sure...

but surely couldnt you just convert one of your existing tanks to rainwater?

Don't forget that temp changes the pH so when you heat the water up the pH will change. I assume rain water would be very soft so would be good for breeding tetras.

Check the hardness Lud, this is an important parameter in spawning many species.

egads! yes check the hardness *facepalms*
