Thanks for looking.I have a 75g tank,with 2 emporer 400 filters,2 aquaclear 4000 powerheads.I bought playsand and how deep of base should it be and how much livesand should I mix(ratio).This is going to be FO(damsels and clowns) for now but I will like to get liverock when funds permit,but people tell me different answers on lighting.I have a regular striplight(flourescent).Will this suffice or can or do I have to get different bulbs or a whole new lighting setup?Also about skimmers?to skim or not to skim?LFS said no,but some people say yes??Will the emporer filters be sufficient for my needs?I've been doing freshwater for eons and thats what I had for the tank when I bought 5 years ago.If adding liverock later do I need to qaurentine it?I have plenty of questions and had most of them answered by reading this forum.I appreciate your help and knowlegde saltwater gods :bowing:
