I have a 5.5 gallon with 6+babies red cherry shrimp. I have a piece of driftwood in there that makes the water SO stained. I know shrimp don't like or need big/frequent water changes, but I can barely see my shrimp! I was so peeved by it I did a 60% water change a few days ago, and added the new water over the whole day to avoid shock (everyone seems to be doing fine) and the tank looked so good after! It was so clear! But it's already stained like crazy again. So what should I do? I really like the stick and so do the shrimp, plus a bunch of my plants are growing on it, so I'd rather not remove it. I don't mind frequent water changes but of course I don't want to stress or harm my little friends.
