I belive you said it yourself,your at your number.I would leave it alone.
Hi all,
I have been browsing the forums for quite a while, however this is my first post here and really hoping somone can shed some light.
I have a breeding pair and would obviously like to try and breed them, however my tap water has a tds of over 1000!!!! After being filtered by the RO, this manages to go down to 75 which in reality is the perfect start for breeding. I was just wondering if I should still add remineralization chemicals or leave as is. Obviously by remineralising the tds will go up! No sure how to go about it... What would you suggest?
Thanks.

It looks like you've got about 8% of the minerals you started with, so I think leave it right where it is.
I start with TDS of 400, and after RO have about 20ppm... I usually add a little something for fry but 70 is a pretty good number.
With water like yours maybe you could bottle the RO waste and sell it as remineralizer!

Here is the removal rate for various ions given for one of my inexpensive RO filters.
If these numbers are to be trusted, your filtered water provides a fairly even cross section of your source water. The only one that stands out is boron/borate, which would be present in the filtered water at a higher percentage relative to the others, if you even have Boron to begin with.
Is that near-brackish water of yours that high in TDS because of salinity, or do you have hard water deposits?

Wow.... Thanks for that but it is a bit too technical for me to digest! but after a while I kind of got the hang of it.... As you said I should remain with a half decent amount of minerals which looks to be enough for my breeding pair.
Salinity is nil, mainly my issue is hard water deposits.
Are you running your water thru a water softener and then thru your RO unit?
Pat
Your discus are talking to you....are you listening
I forgot all about water softeners. That's why I bypassed ours, to avoid having mostly sodium.
No water softener. Directly to ro
Just did a massive water change and got the tds to 91. Will do one again tomorrow and should settle around 70 ish
I would just be careful to watch your KH level to avoid any ph swings
Kh is currently at 3... Should be kind of safe. (Or so I hope)
Looks good to me.
That's the Only good thing about hard water, when it comes out of the RO its ready to go. Except you probably still have to age it.

Fingers crossed! 😃
Thanks for your help!
