I've decided to try & use rainwater during my regular water changes. Nothing to do with saving water, more due to the fact I live in East Anglia, which is renown as a hard water area. Bought a new water butt, fitted it to the existing downpipe from the guttering, (after a damn good clean) Hey Presto.... all I need now is some rain, doubt I will have to wait to long somehow.
The white pipe is about 200mm long filled with filter-floss, to catch any crap. Will let you know how it goes.

Cool, it'll be interesting to see how that progresses Richard. Is that container food-grade by the way? I've heard bad things about some water butts leaching odd chemicals into the water. Can anyone confirm/deny?

I was actually asking because I reckon you'll be ok using that one Richard. Just wondered if anyone else had heard the rumour?

I've heard of the 'food grade' containers, in fact I used to work within the food industry, I was always under the assumption that food-grade containers were made a bit stronger with a better seal, which would make sense, if you think about it. But I am fairly comfortable using what I have, I guess we will have to wait & see if it is suitable, only time will tell.

i'm waiting on my food grade butt arriving. it was used to store lemon juice. so any leeching will only bring my ph down,lol.
i'm sure all food grade butts are fine as they are designed not to leech.
be careful though, some folk are selling drums used to store engine oils, etc without telling folk.

Getting the first rain now, since I set up my new water trap, its about a quarter full at the moment, will wait until tomorrow, then I'm going to test some, purely out of curiousity, hopefully by the time I do a weekly change I will have collected enough.

i've always been told not to collect the first 15 minutes of rain as it washes all the pollutants out of the air, both big and small. so i have a diverter with a tap on, so i can open it up whenever i want.

Right, tested the water collected in the new waterbutt, these are the results

pH - 7.2
nitrite - 0
nitrate - 5
ammonia - 0.25

I expected the pH to be a bit lower, but overall it seems ok, suppose the big test will be when I actually add some when I do a water change,
I have not got any other test kits, do you think I will need to invest?

lol, sorry m8, didn't see the arrow.
hmm, water perams seem a bit off to me. there is no ammonia in mine and ph is around 5.5
i'll do another test in the morning to compare.
good idea to test hardness to.

Thanks for that, I'll keep an eye on mine as well, don't think I will risk adding any to the tank yet, until it settles

Yeah that ammonia reading is weird, and the pH is higher than expected. Is the test kit a new one Richard?

Right, think I may have this sorted..... I am using an API test kit, instead of adding from bottles 1&2 before shaking, I was giving it a good shake between 1 & 2, just done another test, readings are

Nitrite 0
Nitrate 10
Ammonia 0
pH 6.8

Think i will err on the side of caution & do another check before I add any to the tank.

hmm, ph still seems high for rain water. is there anything that might be pushing it up. perhaps get a test from a shop to confirm your results. i do this now and again as test kits can go 'off'.
but still a good usable water, and with no buffer it will drop even further as it ages.
i did all my water changes with rain water yesterday.

Is the water running off something perhaps?
