Can I just fill new tank with tank water plus rest with new water and add the rock I've already got to tank them move fish over so it's like doin big wc
Yes I've done it twice 36to46 then 46to 92. I looked at it the same way large wc use all your rock and water I used my sand and added more. No problems I added like 75lbs of base rock to .
scratch that there was casualty.
my leds took a dip on the side with the control board
now they turn on but i have no control over the timer or switching between light colors.
they turn on though, and all the lights work.
if anyone has any advice that'd be great
