So I know many people suggest using crushed coral to stabilize ph levels. Would crushed oyster shells work as well? I read some were these work well. Has anybody had any expiriance using them? Also is a 6.8-7.0 ph okay for my ryukins? If its safe I'd rather just keep it stable instead of messing with it. One of my ryukins has gill curl so the stress could make it worse.
