Upgraded Axolotl Tank - Littlefish

Phew, this is taking more effort than I expected.
I've got the sand and 300L of water in the tank.
I set up the FX4 today, which was more of a struggle than I was led to believe. I'm certain this was more to do with me being quite short, and dealing with a larger tank than I have previously. The small step/stool thingy I use is good, but I could have done with being closer to 6ft tall to have made it actually easy. 
I'm currently having a very serious think about the placement of decor. I visited a few LFS today to pick up some bits, saw a turtle ramp, and wondered if the axolotls would like it. The younger ones do climb to the top of the large hide they have in their tank, and ther older ones climb the rocks and decor they have in their tank, so I thought I'd give it a go. Just not sure about placement, along with the placement of other decor.
I'd post some pics, but my moving of decor has stirred up the sand a bit and it's looking a bit cloudy.
Hopefully this will be settled by the morning, then I can finalise the decor placement, test the water (due to my dodgy pH change issues), then perhaps consider moving the first 3 'lotls into their new home. 

The water has cleared overnight, so I should be able to get some pics today.
I'll probably get some pics with the tank as it is, before I do any more planting & placement of decor, as I expect to stir up the sand a bit again today.
 

Oh wow, @Littlefish - these look absolutely fantastic... like a dream home for the axolotls! Would be fantastic if you could take video footage of their exploration of their new home but, if not, a very detailed description of how they find it as I reckon they'll be chuffed to bits!

All my other planted tanks have appropriate planting substrate with a layer of sand on the top, but axolotls tend to move the substrate around, so I've gone with root tabs and rocks to avoid them digging it up. I've not relied just on root tabs before, so I'm hoping it works.

Hope everyone settles in ok.  What's the axolotl equivalent of a brew and biccie?

Let me know how you get on re plants as I'm on root tabs only and must admit some of the plants are struggling... think those were swords I saw, fortunately they are doing ok.

Looking... er.... towely. 

I hope they're appreciative of all the effort you've put in for them.

@ColinB We have the special marine versions - Beach towels 

They are such amazing, almost comical, creatures - they must provide hours of entertainment.

They are adorably goofy, and far from elegant. They are not the most active creatures, unless it's feeding time. 

I can certainly say that the output from the FX4 is a bit too strong for their liking. Unfortunately strong flow can stress axolotls, so I'll be putting some filter sponge over the outflow for now, until I can sort out a spray bar.

Have done some more planting and added a divider.
The older 3 axolotls have been moved to the other side of the large tank.
The lights are off and the tank is decorated with towels for this evening, but I have managed to get some dark pictures of El Bandito standing on a rock, Mr Pringles quietly sitting on a hide, and Dafydd investigating the underside of the turtle ramp.
Hopefully they will start to settle in this evening, then tomorrow I may be able to get some better pictures of the whole tank.
