I am considering purchasing this as a compromise with my mom, I want a 55 gallon saltwater set up, but she thinks it's be to expensive, so it's out of the picture....... anyways, i dont know how hard it is to care for one like this, or how much it cost.... if anyone knows please let me know. I also would like to know anything else you hve to say about a setup like this (like is this a decent price) please reply asap, thank you.

you need to do a 10% water change then test again tomorrow thats the only thing that will take the ammonia down, you probably had some die off during the move.
you might have just gotten a mean clown some can be mean give him so time and see what happens.

will do, and aren't clowns supposed to be nice and make balloons and pack into tiny cars? lol

did an ammonia test a moment ago..... down to .25ppm so it seems to be going down, i think the spike was caused by me not knowing that the pump/filter wasnt working properly ted first day that i got it...
