Jmedic25 said:Tank looks sick D, Love it...You may have to adjust your flow some because your FX may push the sand around and cause dunes. I can tell but keep it shallow like 2 inches so you dont get gas build up. Also when your clean your glass on the inside near the sand line be careful you dont pick up a grain and scratch your glass. Also dont put any trumpet snails in like we talked about before. They stir san yes, but I had a mass explosion of the darn things and I do not overfeed. Take looks awesome, I may call tomorrow. Good work Bro
Gases can build up in sand but it's honestly not the end of the world. The biggest fear is if a gas bubble (and it would need to be a fairly large one) to get trapped underneath something and slowly have a constant flow of water across it causing it to leach out nitrItes. I've never once in my experiences seen it but you also need to think cichlids are constantly moving sand especially when digging holes. If you know of a specific spot that gets no attention from them every couple months just run an object through the sand to release any possible pockets.
Think about it this way. If a pocket builds up and eventually breaks through the surface of the substrate it forms a bubble. That bubble then floats to the top of the tank and pop, all gases are released outside the tank. Not really a big deal.
I know someone is going to say I'm wrong but I've done quite the bit of research on this and have never actually read of someone losing fish
HUKIT said:Anaerobic gas pockets are present but they are harmless, as the bacteria start transforming due to the lack of oxygen they start reducing iron and sulfur. One of the by-products of this is hydrogen sulfide which is truly dangerous but when exposed to oxygenated water it's utterly harmless...just another perpetuated myth reguritated on aquarium forums.
