Hey just got an oxyclone 20 site. It came with a recirculation pump and an airstone with its own air pump. I bought an upgraded pump so I can run 2 airstones at the bottom instead of one. Is it necessary to use the recirculation pump? I've seen diy clone setups that only use the airstones and they seem to work great. Just wondering if it's actually needed? I've heard they can raise water temp which wouldn't be good in my case. Thanks dudes!!
