I'm looking to add a school of cories and Oto's to my 55 but as I have conditioned water, Hardness ratings are 1 and 3.

How Sensitive are these guys to soft water?

Ph is between 7.0-7.4 normally.

Thanks!

Are you saying you have a "salt" water softener? Corys & otos like soft water but not salty water. I "think" it's potassium chloride that is very expensive but safer for salt hating fish. Look that up...

Can you bypass the water softener? & what are your "natural" presoftener water parameters? Hard or salt...neither are those species preferences. pH is not an issue for you, they should be ok unless wild caughts....otos might be...corys less so unless an unusual species.

Tell us more please...

the water filtration uses Ionization method so not really salty per se.

As an upside, water quality must be good as my blue acaras just hatched a bunch of BABIES!
