Bored into leaving
im guessing you are getting ich from low water quality. or stress on the fish
Then you are guessing wrong. You get ich from bringing something afflicted with ich into the aquarium (such as a fish, decor or plants). It has no dormant stage and if you get it and treat effectively so that all the ich are killed, it will not come back unless re-introduced.
As a side note, ich cannot tolerate being dried out. If you want to make sure a tank is clear of ich let it completely dry out.
water changes should be caryed out with room temp water, you acheive this by making the water 24 hours before adding it,
Should you? I have been doing mine straight from the tap, as does pretty much everyone with a large tank. When I am changing 100 gallons a week I am not going to be leaving vats of water around the flat. Even in the middle of winter changing a regular amount (10-20%) is not going to lower the temp by more than a couple of degrees C, and this is more than fine for any fish to take, even the somewhat fragile rays.
weekly water changes are essentual, i'de say twice weekly both 10% so you do a 20% water change weekly.
2 10% changes are not the same as 1 20% change. The second 10% change will removes some of the water that has only just gone in at the last change. After the first 10% change, 10% of the water is new water, meaning the second change will remove 1/10 as new water. The result is that 2 10% changes are actually 19% of the original amount changed, not 20%. A small amount when talking about 2 10% or 1 20% changes, but it becomes more of a factor when comparing 2 25% with a 50%, so it is important that people reading (rather than yourself) understand the maths.
diet (the high lighted are not nesasary, it will say what they are for)
diet should be varied to keep you fish in good condition.
Actually, flake foods are designed (after scientific research) to contain all the nutrients a fish needs for life. If a fish will take flake then you can feed it on flake for life and be sure to get it all the nutrients it needs.
