Hey, my name is John and I can't grow corals.

I've been in the hobby a year now and have had zero success growing corals. They open and close everyday and slowly wither away over months and months of time. I've been brainstorming on this page and with my local club, and nothing seems to work. I, like many other newbies, caught the reefing bug and moved too fast and was trying to be cheap about things. I bought my used 46 gallon bowfront off craigslist and was dying to get it started.

I used a HOB filter along with... you guessed it, tap water! I cycled the tank using BioSpira and threw a pair of clowns in there. I did my weekly 10% water changes with Reef Crystals mixed with tap water. After my diatoms never went away I decided to buy a cheap RODI unit but skipped the TDS meter (trying to cut corners). I added a purple mushrrom that somehow survived all my errors. I was using Orbit LEDs on 100% both channels for 12 hours a day. I put some baffles in a 10 gallon tank and made a PVC overflow. I added a SCA-301 skimmer and I thought I was on top of things.

I found a cheap TDS meter on Amazon and my RODI water was reading 250 TDS. So, I decided to buy my RO water from the LFS and it read 89 TDS. I stuck with that for a while and never tested my water. I bought a refractometer and to my surprise my salinity was ok at 1.025. My substrate was crushed coral. I continued to build up my fish list and was feeding them NLS cichlid pellets... I know.. I know... I finally coughed up the money for some Salifert and Hanna test kits. My levels were as follows
N - 50
P = .04 (how in the heck???)
ca - 320
Alk - 8.15
Mag - 1020
Temp - 78
Ph - 8.1

I talked to my LFS guy and he recommended some Kent Marine products to manually dose, and I did that once a week. I kept things kind of stable for about 2 months. Along the way I killed zoas, duncans, hammers, blastos, montipora digitata, kenya tree, and 2 leather corals. My blue xenia is sowly melting away as we speak. I've got my nitrates down to 25 and my other levels are somewhat in check.

This weekend at the LFS we were talking again and I told the owner I bought my tank used from a cichlid guy (hence the NLS pellets). He told me that the previous owner may have dosed copper in the tank and that could be the reason for all my troubles. I went online and found a used 72 gallon bowfront that was reef ready, had a stand, sump, and broken T5 light fixture for less money than I paid for all of my test kits. I bought it.

Now, I'm going to take a years worth of learning combined with a used SW tank to make my dream of keeping a reef true. So, if you wish, follow along and throw out suggestons as a re-build this 72.

No, that is a custom LED fixture my LFS guy makes. It's an aquaticlife 48 inch 6 bulb fixture that needs some work (not in the picture above)
 
What kind of par are you getting in the tank?
 
In my current 45 gal, I have no clue. The 72 gal is not set up yet. The above picture is what the seller posted. The LEDs in the pic did not come with the tank. The tank came with a T5 fixture in need of a new ballast. I've adjusted the Orbit LED fixture on my 46 gallon slowly over the past year and nothing seems to produce growth, just slow melting of corals.
 
You want to get your baselines in better sync. Mg & Ca are little low.
 
Here are some pics of the new tank before renovating it/

This tank was not maintained well. Salt Creep all over the inside of the stancd, the paint on the back is chipping, the sump is ok, The tank is drilled, but I bet it is a loud one. I plan on cleaning it up and painting the inside of the stand white, doing a blue plastidip background, and drilling the tank for a ghost overflow and return.

This switchboard came with it also to be mounted behind the tank. Is this safe to have behind the aquarium? Should I build a cover for the outlets, or ditch this idea all together?

Now for the T5 fixture... I contacted aquatic life and they sell a new ballast and the replacement LEDs for a little over a hundred bucks, so it should be a cheap repair. Does anyone have any experience with these lights? It's a 48" T5 HO with 4 lunar LEDs.

I would ditch that wiring harness, Too dangerous..
 
I'm going to work on the stand first. I plan on cleaning all the salt creep off and prepping the wooden stand for plastidip spray paint. White on the inside and flat black on the outside. Is there a good way to clean off the salt creep other than a wet rag?
 
The plastidip stuck to the tape in some areas. I would choose a different product if I had to do it again. I had to put 10 coats of white to fully cover the black original color.

Great Job!! It looks like you have put a ton of time and elbow grease into this.

I personally would ditch the switch board, it looks like a safety issue and an eye swore. But it looks like you are headed in that direction anyway, with the ADJ Power Strip. I considered getting a large power strip for my new build but couldn't find a place to mount it. I think that the Power Strip is a great idea!

Here is a tip, many reefers use filter socks, I personally don't like them (I hate changing them out every other day). But what I do (and I see them in the background of your pictures) is, take a bio-bag and rubber band it in the sump on your return from your display tank (the same place you would put a filter sock). This doesn’t do a great job of cleaning the water, though it does help. But it really quiets down the return. When you first put it on, it will make a sizzling noise but after that it is quiet.

I am excited to see how this turns out!
