I am an extreme novice in saltwater aquaria, I have a 55 gallon tank that has been running now for three weeks with 3 clownfish. My filtration consists of an undergravel filter w/2 powerheads, 1 Fluval 304 canister, and one seaclone 100 protein skimmer (which by the way, Im not sure if I am using it correctly). I have a few questions, and I would exteremey appreciate any pointers that anyone may have for me.
1. I have been reading quite a bit and have decided I do not want to use an undergravel filter anymore, since it has been running for 3 weeks, would it be ok for me to completely take it out of my tank without harming the fish? Will my fluval be ok by itself?
2. I am definitely considering another type of filter, at the moment a Magnum 350 with Biowheel or an Eheim wet/dry. I do not have too much money to spare, but at the same time I want something decent. Any suggestions would be helpful.
3. I purchased a Coral-Banded Shrimp today, it died within 5 minutes of introducing it into my tank
. My fish have been in the tank since I set it up and they are fine, so I am not too sure what killed it. Again, any ideas helpful.
4. Last but not least, can I use any of the neat looking rocks that are abundant where I live? If so, can I mix them with live rock? Not sure what kind of rocks they are, I just know that they would look pretty in an aquarium.
If anyone can suggest anything that may help me on my journey, please do. I know I have much to learn, but I am willing to give it my best shot.
