Discus and WC's

[doogie]

Hi all, well I have setup a, new to me, 90G BB tank and have 9 local discus. My question is I have been doing daily WC's of 33%. Theses discus are responding well to it,or so I think, I want to raise the daily WC's to 50%, should I or should'nt I?

Thanks

Depends on what you want to achieve.
If it's the optimum-sized discus growth in the shortest time frame (since you have a BB tank), then 50% would be somewhat better than 33%. (75% would be even better.)
In any event, if you feel like upping it to 50%, why don't you - certainly won't hurt.
If that's not your goal necessarily, and you're happy with your current results, no need to change anything that you're comfortable with.
