any tips on getting rid of the generic textures in the distance?

Is there anything I can do to get rid of the generic water textures that draw in the distance, especially when flying higher than FL20? I have tried all types of add-on water and everything causes this problem. Is there any add-on water that works better? or are fs9.cfg settings I can change? I fly with real weather so changing the visibility everytime isn't an option. Thanks!
