how big r the rays? a waterchange once a week isnt enough...
did it look like this?
Nic;2650796; said:you cant really say that... on moderate bio loads ive done only one change a week and was fine... at one point i had to do 3 or 4 50% a week... not knowing the tank or its params you cant say a water change once a week isnt enough... my friend pond is so well established he was only doing a water changed every month maybe 2.... it was topped off as needed but that was it..
