My son and I would like to set up a 30g tank. We want to start with live rock, live sand and fish. I have a Eheim Pro II canister for filtration. It has 2 baskets of media & each is covered with filter material. Is there a difference in quality of live rock?? I have seen several sites that carry 12 different kinds...what is good? Good place to buy it from without having to take out a second mortgage? I think I want a hang on the back protein skimmer (good brand??). An inline uv sterilizer (good brand? ). A heater that I can set the exact temp.... and either T5 lights or LED but find that there are so many choices in this department that I don't know what to select .... and keep the cost down. I have an old hood that has a fluorescent lamp but not sure if this will produce enough light to keep the live rock alive. Don't know if I will need a power head for extra water movement or not. I need to buy a portable RO device that I can hook up to a bathroom faucet. A good brand to buy that works well? Have I missed any equipment?? I need a good testing kit....what would be a good brand to buy?? Lastly, how do I find my post...is there a button or link where I check on just my post?? I have been on the internet and other sites reading and reading..... the articles haven't made me more comfortable about setting up a tank...just scared the heck out of me. I have a catalog from Dr Foster & Smith....is that a good place to buy things or too expensive. Is there a better place?
