hi! i'm new to this hobby and i think i've had my tank setupped for... five months na! so far everythings doing fine with my fishes and just this week, i added corals and they're like wow! so cool! my tank is 50gallons and i only use undergravel filters w/ powerheads on top of the tube. i read a book that sez that this type of filtration is rather effective but i dont really know about that, thats why i'm here to ask the experts. say, i've read some of the forum topics here and i was like blown away completely! u guys really know what you're doing and i really want to learn more from you people, like take this hobby a level higher, help me pretty please!
i just want to know what exactly do i need- equipments etc. like the sump? or the fuge or chaetos? i mean what are those? are they really necessary? in kartimar they just tell you that you need this and that and i don't think they actually know what they're saying.
oh, will you look at the time, i'm late na! hope you guys reply, and by the way, this site rocks!
