Aquatop CPS-1

My cps-1 wave maker is just too strong, the only coral I have that likes the high flow is my torch, oddly enough my hammer hates it. Is there anyway I could somehow tweak it and make it less powerful or do I have to buy a low flow wave maker. If I have to buy a new wave maker, could you suggest to me some that aren't super pricey?
Thanks :)
