Right, so I am currently consolidating my hobby. I plan to reduce all my Freshwater into my Red Sea Max 130D and leave this as the office tank. At home I will have the 5G which I am currently running and will begin on the work to the 60x30x30 freshwater that I have to turn this into a reef. The 5G will then act as a QT/Observation tank for new arrivals.

So the 5G, very simple build.

So i pinched the floating rocks idea from @Animal, cheers Dave. 3 Kg of Dry Rock was siliconed to the glass, this was structurally supported by forcing crushed coral into the silicone to form a hardened seam under where the rock meets the glass improving the structural strength of the join by spreading the load over a wider area.

Added 7.5KG of "Live" Sand, Samoa Pink, which is finer graded than Fiji Pink and personally i think looks and works great in Pico's and smaller Nano's as the weight of the grain is still substantial enough to stay mostly in place. Over the month of April i gradually reduced the depth of the sand bed until I was satisfied with it, most Kelley i have removed roughly a third, so we'll call it 5kg of live sand.

The rock that the Fan Worm is on, is one of the first that i bought in the hobby over a year ago now. Fully encrusted with worms and life. I used this to seed the rest of the dry rock in the tank (perhaps 300-400G cycled rock) , interestingly it never seems to get covered in any major algae growth...

Blue Legged Hermit was the only Clean up Crew i could find until last week when I placed an order for more CuC (and a Hammer), it has done okay to be honest. The majority of the rock on the sand bed has been kept clear as have the undersides of the rocks, the upper shelf however i will ignore until my snails arrive!

I aim to focus on two, possibly three different Euphyllidae Genus Corals.
Hammers - Branching and Wall
Catalaphyllia Jardeni (Elegeance)

Fox Coral - Is a long term item on my wish list!

Looking good Ratvan. The 60x30x30 tank that you mentioned, is that in inches? If so, it'll make for an interesting tank.
I mention this as my tank is about 60" long, I could easily have had it smaller, but something occured to me about caged animals, if we can give the illusion of more space, surely they'll be happier?
Considering that most our pets are going to be reef shallows occupants, I never thought that too much depth would be important over the distance they'd have to swim to get from one end of the tank to the other-just my warped way of seeing things 

No centimetres, it's about 60 litres. I'm planning on cutting it down so it's more like 60x30x20. Really love shallow reefs, just keep it simple and got for a fringe reef theme of tabling corals (scroll, pagoda cup etc). Sadly I rent so can't have the tank of my dreams just yet. It is a 5 foot long so I can Tang

Small systems are harder to control due to swings in the finite water volume. Good luck, I wouldn't be bothered with the water changes!

Very true, I hope eventually to be able to push out water changes to once a month when things settle in. Another 2 or so months and some purchases to make yet but should be workable.

It's got perhaps a 12 to 18 month life before I upgrade to a decent shallow system, was looking at a XL425 but think I might order a standard and cut it shallow and run on same principles as this one, water movement, heat and fish waste

Amazing how powerful those little lights are. Looking good there!

Urgh I hate waiting

Hammer has potential, nice and bright

Most likely a monti

I'm thinking that the bonus free frag I received is a superman montipora as it is blue bodies with red polyps. Might stick that in the spec 3.

Need to work out how to take good photos of red corals under blue lights...

Result!  I had one of those and it was a good grower and very brightly coloured.  👍🏻

Is that in the 85L? I need to re read that thread
