a type of snail they are actually not a problem there alge grazers got a couple in my tank, like a little bonus with live rock i think there is a little more info on them in the hitchhiker furom might wanna check that out on here
if you look at your booklet that came with the bc it should say that any upkeep or replacing of the lights and ballasts is at like 9 months so if you contact oceanic they should be more than happy to help you since you are only at 6 and they have like a year warranty i think
keep an eye on that snail i had found one in my tank, i was just siting there watching the tank and i saw a cloud of like dust being flung off my lr so i thought it was a pod of some sort then a few days later i saw it again but it kept doing it then i saw that little guy and he was the one...
i had the same problem then the fan just stoped working and i replaced it now the other one is making the noise. depending on how long ago you got your cube, it should be easy to get it replaced by oceanic if it burns out.
hi i love your tanks by the way. i was wondering you said you run the biocube skimmer, i just picked one up and was wondering how far up th chamber do you run the bubbles. any help at all would be great thx.
