Picked up a 40gallon breeder from petco thanks to the $1/gallon sale a few weeks ago i couldnt help it. So on starts the long process of trying to save money and set this tank up better than my last one. This will be my second tank (the first was a standard 55gal mixed reef about 5yrs ago) I never really wanted to get rid of my 55 but we moved and didnt really have the space for it so out the door it went. I really want to try and do this right. So input is the reason for the build thread tell me if im doing something stupid lol. Going for a mixed reef. Heres a list of things i will need to do 1. Build stand (I have been working on it however i am no bob vila so its taking me some time) 2. Drill and Paint tank with glassholes overflow and return kit (did this last night and am very pleased with it so far) 3. DIY sump (plan for a 20 long from petco). Need to figure out where to get the baffles cut and what i should use for them glass plexy acrylic?? 4. Plumbing (going real simple with the plumbing straight down and straight up for the most part) 5. Return pump (need advice on this was considering a mag 7 as suggested by someone else on her, but i am open to other options. Like anyone else i would like it to be relatively quiet. 6. Skimmer (i have a reef octopus skimmer that i had bought for the 55 a few years ago and a buddy of mine has it now and he is open to me taking it back however he said he thinks the pump is giving off some voltage into the water. I havent looked at it myself yet but i will most likely replace the pump on it before i use it. I believe its the classic 110) 7. Powerheads/Wavemaker (this i have no idea on what i need or how many or what so input would be appreciated. I know these suckers can get expensive and i am not trying to spend alot on these if i can help it.) 8. Rock and sand (i am open to suggestions for rock and sand, i would like to start with all dry rock and add some bacteria to let it cycle instead of adding live rock. I had pretty fine sand in the 55g and it was a little bit of a hassle to get to stay put so maybe something a little coarser this time around idk yet. 9. Light ( i have been back and forth on what kind of light i want first it was an ai prime hd but i didnt thnk that would be enough so i went to a chinese black box and now i think i have landed on the Ocean Revive Arctic T247. The controllability looks like a great feature for a decent price. 10. Need an RO/DI unit still Here are a few pics of what i have so far Let me know thoughts and suggestions on equipment thanks.
