For both fish it would be best if you could get a new and separate tank for the oto. I suggest for now just keep lights on that timer and see what happens, although 25% is a little low per week but if your nitrates are below 20 before a water change and the algae problem goes away after keeping your lights on a timer then don't worry about that since you have a planted tank. Also during the water change go ahead and manually wipe off the algae off the side of the walls with your hand or you can get one of those magnets from a pet store to do that. I feel like once your plants grow in more the algae won't be able to compete anymore anyways.
