Sorry, I've not had that brand, 2 of mine are the ones that came with the Top Fin aquariums & the 3rd is Aqueon. I would call the manufacturer, you should be able to look them up online or if you happen to still have a receipt take it back to the store. Were they both the same brand, if so I think I would stay away from that brand. I'd definitely call or write manufacturer and see if they'd be willing to do anything.
