Ok i have never had a saltwater fishtank before and i wanted to start one i work at a pet store so i am around alot of fish everyday. My first question is if i buy a used 90 gallon fishtank on ebay will i have to go thru the cycle?

Also it comes with
90GAL TANK SETUP FOR REEF AND SALT FISH AND MORE

OAK STAND AND HOOD 48" WIDE

150GAL WET/DRY FILTER WITH PROTEIN SKIMMER

2-175WATT MH WITH ELECTRONIC BALLASTS

2-22" PFO FLOURESENT LAMPS

MAGNIUM 350 COMPLETE W ALL PARTS

WAVE MAKER SCWD WITH HOSES

7-POWER HEADS

A LOT OF MISC PARTS,FOOD,HARDWARE AND MORE

Will this be good for some saltwater fish like a stingray that are place has?

Also what types of fish can be added with a stingray?

Well I have a 29 gallon Oceanic Biocube and I have had my tank setup for about a month. I got two fish a couple weeks ago. 1 false percula clownfish and 1 royal gramma. I am just wondering what other fish I should get. I was thinking maybe 4 blue/green reef chromis. Is that okay? Thanks!
Okay i’m not going to get a shark… or a turtle.

Ok i just picked up all the live rock i need…here is my tank setup

55 gallon
30lbs agronite sand
20lbs live sand
1lbs live sand from an established tank
60lbs (or more) of FULLY CURED liverock/that i bought from a established tank (/lb)

Fluval 305 filter (new filter media)(no access to used media)
Coral life Super Skimmer (65gallon)
Coral life Actinic light 260watts/10k

now thats out of the way, i was told by someone to do a FISHLESS cycle, and to add pure amonia (about 3-4ml a day) for 5 days….its day 3…i have gotten the PPM up to 1.5 or so….

nitrites and nitrates still read 0, pH is 8.2, salinity is 1.022

CONSIDERING i have 1lb of livesand from an established tank AND 60lbs or CURED live rock, should i even have to cycle the tank? or should it not already by cycled? kind like a clone tank…

i was assuming i should stop adding ammonia and check the nitrites every day until they spike? or will that not happen since i have so much from an old tank?

I want to get a small one for my room. I already have a bigger regular tank setup in the computer room…but I am looking for something that is low maint(for a reef tank any ways) stylish and quiet. I’m thinking more along the size of 12 to 14 gal.
