Hi all,
It seems that noone has actually shared the best water perameters for these little fellas yet.
I'm still new to it all but here's mine since I started adding a bit of RO to the tap water. I don't know if its the right water but thats how I have it A.T.M and since noone knowledgeable has left any info it'll stay that way unless anyone say's different.

pH: 6.8
KH: 10d
GH: 10d
NH3: 0
NO2: 0
NO3: 0-5

The water around here is incredibly hard which I found out the hard way with my Tetra's but the pH is 7.3 out of the tap so the pH has to suffer for the hardness to be brought down unless I start using rain water??
Does anyone have any words of wisdom on rain water?

RO is the best way to regulate your water parameters. I personally would never use rainwater after a friend started using rain water in his fish house and after a few weeks started to lose fish. Nothing else had changed other than he was using rain water. The suggestion was that something was getting into the rain water be it in the sky or on the way to the collection point. He lived in the country as well so you wouldn't have thought there would have been any problems

I must admit I'm very lazy when it comes to testing my tank water but last time I did it was around 6.7ph GH 8 KH 5 temp 26c

Yes, definitely proceed with caution. It seems that every time the subject comes up the general consensus is that it's a bad practice.

My only other option would be to run the rain through an RO unit to remove any toxins. Since it's not loaded with dissolved minerals to foul the filters and membrane, I should get good service from them.

At the present, and for the past several years, I must just be extremely lucky, (knock on wood), as fish and plants are doing extremely well with rain water. We have abundant wildlife in this area and I'm only about 2 miles from one of the best trout fishing rivers in the mid-west of the USA. The rain that falls here must still be close to what nature intended.

Cheers, would it be wise to lower the GH even more then?
What I mean is do the CPD's require me to lower the hardness or are they happy in moderately hard water (16d)

Things are kind of on hold A.T.M since I made a big boo boo and forgot to add tapsafe, now I've put chlorine in with everything and its crashed.
I'm doing 2 10% changes a day at the mo and the cory's have started laying eggs. What a nightmare.....

I'm gonna crack on with the 25% RO water even though its gonna be very expensive for a couple of weeks. It will benefit both species anyway.

I've done 2 x 30% water changes 1 last night, 1 this morning and the tests are matching up tonight with my ammonia stable at less than 0.5mg/l, the fish look pretty happy for a change & the snails are going back into the water.

I dont understand how the plants didn't kick in removing the ammonia, there's tons of plants in a 100l tank and only 4 cory's & a handfull of tiny danio's and I was feeding them next to nothing.
Usually when I set up a new tank I dont even get any spikes since the plants take care of it all. Anyway its under control so hopefully it will stay like that.
Won't make that mistake again!

My water is very hard so I mix 50:50 RO and tap.
