Joining the Ranks

Hi, I have been reefing for just over 2 years now, starting with a 15g, then a 29, then 75... You see where this is headed, right? So this week I am taking the plunge and skipping up a few steps - and getting a 500 gallon tank.

My plan is to DIY most of the rock structures myself and use maybe 20% actual live rock. After building all the rockwork, I will fill the tank and add the LR and go bare bottom FOWLR with ceiling mounted track lighting overhead for about a year. This will get me through the door but it's just phase one.

I will save up and gather sand until I have enough to fill the tank about 8 inches deep, then add the sand over the course of no more than a week. This is phase 2, establishing a DSB.

During the following 6 months (give or take) while the DSB and tank inhabitants learn to love eachother, I will save up again, and replace all the track lighting bulbs with LED fixures built with narrow optics. Phase 3.

Assuming these phases are all relatively successful, I will have an established reef ready tank with a DSB and coral-supportive lighting, so I will begn gradually converting the tank to a mixed reef.

This will be a massive undertaking, unlike anything I have ever done, so before I even move the tank into my house I wanted to start this thread asking for advice and tips. Here are a few things you should know:

1. So far, all I have is the tank and stand. All equipment is yet to be determined. However I am thinking several powerheads for flow and 2 returns (Mag ??) from the sump, and definitely a good sized refugium + turf algae scrubber + protein skimmer. Probably GFO, carbon, and bio pellet reactors as well, but I don't anticipate much need for a calcium reactor.

2. The sump will have to be located in the tank's stand. A potential upgrade to a remote sump isn't going to be an option for at least 2 years.

3. I know, adding the sand after tank is cycled and holding fish is a terrible idea. However, I've done it on a much smaller scale, and I know this - if I decide this tank is too much for me, I want to decide it before I have to scoop out all of the sand!

4. With no set timetable, here is an idea of my most desired stock list:
Niger Trigger, Tang/s (undecided species), Angel/s (undecided species), Mandarin Goby, Diamond Goby, sixline wrasse. Optionally, a small group of chromis. For inverts/corals, I will probably avoid SPS, except maybe some monti cap or tabling varieties. The rest will be soft coral and occasional LPS. My main gem will be anemones, including multiple BTAs, a H. Crispa, a H. Aurora, and at least 3 carpet anemones, 2 being Haddoni, 1 blue 1 red. These will host an undetermined pair of clowfish (I hope).

I would welcome any help/links/insights/warnings you can offer. If you see something wrong with the stocklist, call me out. And if you have suggestions on other fish I could have, let's hear it! I intend to have alot going on in the end, and I hope to have a well-laid plan ahead of me the whole way. :dance:
 
Nice, welcome to the big boy club :) Your plan looks good from what I can see. Powerheads I would definitely recommend Vortech's.
 
Thanks for the encouragement, and James404, thanks for the tip. That will set my startup date back quite a bit due to the price, but I am forcing myself to learn patience and do this one right. Can you recommend size/number/placement? I've never used Vortech, and never set up flow for a tank this size. It's kind of ridiculous to think that my garden hose at full blast would barely make a dent in the overall flow!
 
No problem, cost is definitely a big issue with the vortechs. They are well worth it in my opinion. Your other option might be a closed loop or some tunzes, which are expensive as well.

Personally if it was me setting up a 500g, I would probably try to do 2 MP60s and 2 MP40s, thats a lot of dough though. I'm running 4 MP40s on my 225 for reference.
 
Ok, well that's gonna be my early Christmas gift I guess, lol. But hey, you don't start these projects with empty pockets and expect it to fly. This is good stuff to know before I try to fill it and screw around with flow in a full tank. Thanks for the insights! Just to clarify, I have a 96x30x36 (or so) tank to work with. So I am thinking 1 MP40 3 feet in from each side on the back and then 1 MP60 on each end facing each other. Good? Bad? Irrelevant? I might try to build the rockwork so it stands in the center so I can point 1 MP60 across the back and 1 across the front...

I think that would work well.
 
Have you thought about going "sandless". I find sand holds in the nitrates.

I am putting a premium on owning sand dwelling anemones. If I am having trouble keeping the tank clean I will not add sand and may never even go beyond FOWLR. But if I am doing corals I want Haddonis too, and they live in sand. I am hoping that if I make it deep enough, the DSB properties will help me more than hurt me in dealing with nitrates.
 
A shallow sand bed should not hold nitrates, it should actually lower nitrates by turning it into nitrogen gas bubbles that eventually float to the surface. You can also vacuum a shallow sand bed.

It was my understanding this only happened in deep sand beds, where the lower levels didn't get any oxygen and turned anaerobic. Also, sand anemones require at least 4 inches of sand when full grown.

Is there something bad about running a DSB in a tank? I had always read that it was beneficial as long as it was undisturbed..
 
No worries, I am always looking for helpful tips so I appreciate the intent. I'm not rich so with a tank this size I can't afford to screw up too much. So I welcome as much insight as I can get. :)
