im a newbie and have been researching saltwater aquariums for awhile now... and am planing on buying my set up this week...i plan on going with a fish only with live rock set up....im gonna start with a 29 gallon tank.... i was wondering how much live rock that is recommended....i know most say 1-2lbs for every gal but i was wondering if i could us alil less so i would have more room in my tank but want enough for my fish to hide in....also i was wanted to ask about how long it would take for me to cycle my tank with the rock and sand in it....i know im gonna need a light and was thinking about using a penguin biowheel to filter....is ther any other equipment u recommend me buying...and how big of a heater should i get for this tank... i want to get started on my cycleing sooon so any advice is great....(im completely new)
