adjust the rays to your ph, a stable ph is alot better then trying to keep it at one level when its trying to be at another.
yes the filters sound fine 2 xp4 will cope just fine aslong as they are full of decent quality bio media.
as far as water changes are concernd, less water more often is best. one huge WC a week is ok but its alot better to do a few smaller ones threw the week. it stops the large change in water chemistry so its better for your ray.
i do around a 35 to 40% WC every 2 days on my system.
mine is a rio 400 which is linked to a 4ft x10x15 on the wall above.
filtration 2x ehime external, fluval 4 internal and also ha HOB filter on the top tank. i removed the stupid plastic flow plate from the HOB and filled it to the max with bio media.
then i do around a 35% to 40% WC every 2 days.
