The whitish roots is a good sign. When the root is whitish and then you water it, they should turn green. If it is very wrinkled, it may require soaking for 20 minutes or so.
Take your orchid and the clear plastic pot out of that unvented decorative pot. When these places sell orchids. They expect people to just throw them away when the blooms are done, so they put the plants in everything that is bad for them. Very tight sphag moss and unvented, glazed pots with no drainage.
Orchid roots have to breathe. If they don't get to breathe, due to too much water and not being allowed to dry out a bit, they will rot and die. Then the plant is unable to take up water and is on the road to death. So most orchids cannot sit in water. They have to drain and dry. Other ways to suffocate the roots is to use too fine of a potting material and it does just that. Gathes on the roots and suffocates it.
Be aware of where you are placing your orchid. Keep it out of direct sunlight after 9:30 am and before 4:00 pm. It will get sunburned if not careful. But it likes more light than you were likely lead to believe.
And the ice watering routine has to stop. Phalaenopsis orchids are tropical plants. You are putting ice on their roots. Does that sound like a good idea to you? Personally, I water my orchids 2 times a week. The phals in clear pots get watered only if they need it (roots have turned whitish). I try to use slightly warmer than room temp water with 1/4 teaspoon of fertilizer per gallon. I pour it thru the pot, let it drain and then put the orchid back where it lives.
