Hello.. i just need some help/advice. i recently bought a 35 gallon tank and i decided to start a reef tank. YES, i know it can be quite expensive and its okay since I'm deciding on taking my time and not buy everything at once. The tank i bought it came with 100w heater(aqueon), canister filter(fluval 150), and powerhead(aqueon). I was thinking of adding a skimmer and ive done some research and read somewhere that a tank my size don't "really" need a skimmer as long i do 25%-30% water changes weekly. i also found out that my main filtration would be my live rock, but if y'all could give me any tips on what would be a good filter since I'm thinking of changing it. also what would be good recommendations for skimmers,lighting,live rock etc.... and do i need a sump for my size. THANK YOU!!
