Question about filtering Rain water

[Aqua sobriquet]

That looks fine Pete.

Hi all,

I decided today after rain to do some NH3/NH4 and NO2 tests for my rainwater. Actually is straight after rain.

It looks like rainwater has quite a lot of ammonia. I am not sure if it is safe to use for aquarium. I know plants like ammonia source better than NO3. I know bacteria will convert it. TDS is 36.

The question is about fish and others?


NO2 Looks like is on very minimal level.



And this is my little filter build from plastic bottle and there is filter floss sponge and activated carbon.

I keep activated carbon all week wet like that and there is some brownish places on bottle walls and on that bag.

Is that sth what I should worry about?

Thank you all for any help,

Kind Regards

Pete

Where was the rainwater from? Has it been stored for long.

The water is stored in general water butt 210l which i bought from B&Q.
It has been stored about week after last week rains, and today it added some more water after rain. Well I have almost all water butt now.

The water is collected from the roof of my house.

Kind regards,

Thank you

Pete

No real way of knowing, but it is more likely to be a false result from the test kit than a real reading, purely because there isn't really a mechanism for producing ammonia.

I have been thinking about the same. Because last week I did 20 litres of water change plus I did blackout for 3 days and nothing really happened. I know the effects of this might appear withing next weeks.

But just in case I put internal UV filter to filter this water in aeration. Link below ⬇️

I have done in one buckets over 2 hrs and now I put to the other buckets. As I prepared 2x 10l buckets.

So I hope this will help.

And I am not sure why my activated carbon brown, and bottle inside water floss sponge got brownish in some places.

Could it be any slight of signs any metals? Or sth?

Thank you all,

Kind Regards

You could try dropping a pad of polyester, direct into the water,not as your shown sponge , it should tell you a lot ie metals. As @tam says its expensive to use as a filter media itself in this situation
