the wave makers are mainly for the marine trade but freshies ( as the marine lot ) call us ,,,, can use them as well if u want.
the normal powerheads can not be used on timers ( wave makers ) as they cant take the change of power, this is all info given by paul i think it is ( the main UK hydor rep ). and some marine users have ignored this and used them on wave timers to find they die within a month, those of use who have them will know that when we un plug and re plug in they tend to rattle until they bed in and get going. this is why they cant take the continual change of electric to create waves.
they do have larger powerheads out as stated but these are only available as normal powerhead usages not on timers in the UK ( i believe anyway ) this is based from my experience from the marine side and still talking to a few mates and people in the trade.
instead in the UK after several years we now have the new polario pump which is not hydor.
but this is rather big and chunky bit of kit which sucks from one end and blows the other then switches to suck and blow in the opposit direction and is powerful.
there is also the VorTech powerhead which the main motor sits out side the aquarium and only the prop is inside thus no heat is given out into the water. it works like a magnetic holder and transfers the current this way also , people have said this is a fantastic thing but if not lined up exactly with the outter section is noisy as anything , and will remain so until u line it up.
