Cheers guys, I'd prefer to have the baffles stopping the sideways movement, My old tank is full of drain pipe, jammed solid and i never experienced anything, i was going to stick them in, but they wont fit
I've mailed the tank supplier to see if they can offer any solutions... Thinking of land drain pipe coiled inside at the mo, but will wait until i here back from them.
