Question

my tank
I have a 55 gallon tank i have some driftwood that i have placed in the tank and the water has turned a brownish color i have noted online that this can occur but i was hoping to keep the water clean and clear i have yet to have any problems with my fish (gouramis, tetras, gupps, platys, and a knife fish and placostomus) all are in apparent good health. Is there any way to clear the water up? Also, I'm having trouble with freshwater crabs I've bought 4 now within a day or two they die. I tested my water and fixed the nitrate issue, it was off the chart (kids were feeding them behind my back!), but they still die. Is there anything I can do to help them survive

Answer
Hi Robert,
An easy way to get rid of the amber/brownish water that occurs from driftwood is to do extra water changes and use carbon filtration. Add some extra carbon to your filter or completely change out the old and the carbon will help take out the tint.

As for the crabs. Do you know what kind of crab they are? If they are Fiddlers (the most common available species), its not common for these little critters to perish soon in the aquarium. Its simply due to the fact that they need to get out on land several times a day so a half-land/half-water setup is best for them. Also they need brackish or somewhat salty water you can only achieve by using marine salt meant for saltwater aquariums. Your other fish probably will not tolerate the salt well at all. Water quality issues could definitely be responsible as well as stress from shipping and pet store life.

Again I'm not sure what species these are so I'm only taking a educated guess here. Another commonly available crab is the rainbow crab and they are a primarily land crab they are also wild-caught most of the time too, so if these are your crabs, this would be a good reason for their short short lifespan in your aquarium.

I hope this helps!
