Excited about my marine project :) Suggestions would be very helpful and appreciated

Hi All,

I have kept freshwater fish for years and years now and had pondered the change to marine for a long time.
I was put off for so long by the costs involved and although I still can't say I'm excited to spend almost 2 grand setting up a tank (before the cost of corals & fish), I have finally decided it is going to be worth the change.

So, here's the story...
Any advice or tips will be greatly appreciated and taken on board.

The tank is a 6ft/2ft/2ft which is drilled with 3 x 25mm bulkheads. (1 input & 2 output).

There is no overflow currently but I plan on putting one in.

The tank is sumped with a 5ft /15in/ 15in and there is a 4,500 lph power returning water to the tank and also excess back into the sump.

(i will be adding pictures so if this isn't making too much sense, hopefully they will provide a bit of clarity).

In the sump is jap mat and noodles.

So I want the tank to be a coral tank with small fish so the coral doesn't get eaten. I was told to use crushed coral as a substrate....

getting back to the overflow... currently my two output bulkheads are over on the left hand side of the tank, close to the surface of the water. I was thinking to increase my output, either to redrill the same holes and put a bigger bulkhead on them or, to drill (& plumb) another 2 x 25mm bulkhead holes. Suggestions here would be greatly appreciated.
If I do increase the output, I can obviously increase the input (as most of it gets cycled back into the start of the sump via T bar plumbing, (see pics)). I currently just have a stainless steel strainer on all three bulkheads but was thinking of using a spray bar for the input.. Does this also mean (if the input is strong enough) that i will not require a wavemaker/pump?

I have been told there is a couple of options with the protein skimmer. external, hang off or internal. My preference is to have the protein skimmer working in the sump. is this an option and which one would be the most suited for my situation. I don't mind having to alter the sump or tank or even replacing the current sump for something more appropriate if that's going to be the best for the tank.

Lighting - Led seems to be the way to go? suggestions on the best suited for a 6ft long 2ft deep tank would also be awesome.

I can fully appreciate the expenses involved and know that it is a lot of work. I am recently single so bring it on. hahaha.

I will make a journal with heaps of piccies for this one as I think it should be helpful for others that are just starting out in marine too.

Thanks in advance for your help guys and as I said any advise to make my system more efficient, no matter the cost would be greatly appreciated.
I should also mention that this is not the exact tank but set up the same way and is now empty. The tank i'm using doesn't have submerged bioballs.

Well the first thing I would say is welcome to saltwater. Second I would say is to get rid of the ceramic media and bio balls. Nasty nitrate factories and will cause you major problems in the future. I would invest in a couple hundred pounds of live rock/live sand. This will help better with your filtration then that stuff will. You can definitely do a skimmer in the sump. I run an SWC 160 extreme and love it. I've heard a lot of good stuff about the reef octopus brand as well. LEDs are going to be a larger up front purchase but will save you on monthly lighting expenses. I myself am setting up my 125g with five MH bulbs.

Good luck with the build and I look forward to seeing your progress.
 
Agreed, lose the bio balls and ceramic noodles. Live rock will be enough for bio filtration. Also, submerge those pipes coming of your drain or be prepared for tons of salt creep.

Go with an internal or external skimmer. Your choice based on how you want your set up to function. On this size build, HOB is not going to cut it.

Substrate is a very personal choice. You will hear a lot of people tell you to NOT do crushed coral but I think it depends on how you plan to set it up and your maintenance regimen. Do a LOT of research in this area and make your own decision. You have a lot of options here from bare bottom to sand to lots of different size subtrate up to crushed coral.

Good luck!



Oh, and if you keep the foam, keep only the top piece and plan to clean it often. That too is a potential source of nutrient build up but can also be good nutrient export if attended to right.

My biggest question with this all is about the plumbing and sump setup. I want to make sure I'm setting up correctly and if I'm drilling more holes, that I'm not going to drill one I didn't need
