Hi Guys,
Decided this afternoon I would re-arrange my Malawai Tank, upon removing the Rocks etc I noticed a disgusting smell, said to my son " Can you smell that foul smell" He replied "Yup, it smells like a dead puffer fish from out the beach"
Have only had the sand in the tank for about a month, I do regular Water changes, usually twice a week, but don't probe into the sand just suck the crap off the top of it.
Not sure what is causing this revolting smell, have checked for dead fish, have found nothing, have done a good waterchange, not sure what I should be doing next if anything.
Could there be a build up of bad bacteria in the sand, giving it this shocking smell??
Beginning to think going from gravel to sand was not such a good idea.
