Wow its been along time since ive been on here. Well ive had my 29gal up and running for over a year but in the past two months ive just had LR in my tank and no fish or CUC. The reason for having it empty was that i had a 55g tank just sitting around but i never got to setting it up for SW. Now that i have time i want take a swing at a bigger tank. My Question is, do i have to have my tank drilled or can i just have like 3 powerheads, kind of like the setup i have for my 29.? its been awhile since ive been on here so im going to have to check some things out. im a little rusty. more questions to come
