hey everyone. i am looking at either getting a couple more MJ mods or maybe a couple hydor koralia ph. its been a little while and was wondering for those who have had the hydor koralia powerheads how are they working out? any issues or things you notice that might be of concern, clogging easy, ball joint gets loose, magnet/suction cups holding up? anything else? compared to the MJ mods what are the pro's and con's, if you know?
thanks for any input, i plan on getting a couple of them this week. one thing though, i dont want to sound *%&#$% but i really only want to hear for those that have had them for at least 3 months or so, just because most everything works good for the first couple months. unless of course you had issues before that, i just dont need to hear "they work great but its only been in operation for a couple weeks". the MJ mods i know hold up to running on a wavemaker, at least mine work the same as the day hooked them up a year ago. dont know about how the koralia's fair operating under similar conditions. can anyone enlighten me
?
