600 biomaster 2 vs 350 biomaster.????

I dont think there's much between a 600 or 350 for flow..depending on your media or how much you put in..you get an extra tray.its not like there deeper trays..but its the same diameter...I basically swaped all my trays and media over..there's no difference.quite disappointed really..im also getting continuas purging of air Of which i thought the whole redesign of the heater was about..?..and I'm having real trouble with the heater keeping heat if at all..I don't think there's enough flow..and my filter is not packed either..so basically if I'd known before I'd put everything together I wouldn't of swapped it out...so yeah DISAPPOINTED is the key word here.!!

Great item but should be checked before packed

Item is brilliant with a great adjustable flow for that smaller tank. However item plug was damaged and I was not able to replace like for like even though item was in stock. Resulting in an electrical engineer dealing with it.
