RO water & growth

[henpecked]

I have 4 fry about 8 weeks old now. I keep them in reg tap water like my grown discus. I was wondering if using partial RO would benefit their growth, or is frequent water changes with reg water sufficient?

PS: My tap water TDS is 200. I keep breeders at 50-75 TDS

I am certainly not an expert...but from what I've gathered, smaller fry do better in harder water conditions.....I'm sure some more experience people will give there expert opinions.....
