Setting Up A River Tank - Littlefish

Today is the day that I have actually started the tank that is suitable for the fish that I fell for over a year ago - Sewellia lineolata.
When I got my first temperate tank(s) with zebra danios and v. platies I started looking at other fish, and when I saw a picture of that particular hillstream loach (picture below) my mind was made up. I spent a lot of time researching requirements, and getting distracted by my multiple tank syndrome, but  last Christmas I had a tank delivered that I set aside for the project.
Over the past few weeks I've been buying bits and pieces, plastic tubing, a pump, etc. and this morning I made a start on the river tank manifold.
As you can see, I'm a bit of a girl when it comes to this sort of thing, and I work on a towel on the floor in the living room, rather than a workshop or shed, but at least I'm getting stuff done.
Just stopping for a coffee, and to give the silicone on the base of the manifold a bit of time to start drying, then it's time to carry on with making the in and outflow sections. 

The tank on the right is for the river tank.
The tank on the left houses my 6 mature male axolotls. They were one of the many distractions. 

Nice, I've seen this kind of river setup in videos.  Hillstream loaches are perfect for it.  Will you be putting other fish in or packing it with those ones?

All nice choices.   I'm particularly keen to see some shiners.

I've done some more work on the river manifold tonight. I can honestly say that I have not improved my skills with either super glue or silicone.   
Leaving the pipe work to dry and will try putting it in the tank tomorrow.

@Andy the minion thanks for the offer, but I've just put the manifold in the tank, with the assistance of my ever present helpers - brute force & ignorance.
I ended up buying a dry pump, so I have hose going from the manifold, rather than having the pump heads attached to the pipes. I have some large pieces of wood with which I hope to be able to hide the hose in the corner of the tank.
Most of the pipework on the manifold will be hidden by the sand & rocks, which should also help to hold it in place.
If the whole thing explodes the first time I turn it on I'll be in touch immediately for your sketch of a simpler plumbing method.
I still need to add the filter sponge to the uprights on the left, and will pick that up during my trip to collect the live food from the LFS tomorrow.
Phew, this is quite hard work.

@Andy the minion I had to look that up 
The particular LFS I go to on Fridays have a substantial pond section, so I was hoping to pick up some suitable sponge tomorrow. I'll also be using an FX4 external filter in the tank, so the sponge on the manifold intake is just to stop bits going into the manifold and into the pump.
You are very technical/engineering minded, whereas I'm currently just bumbling along having a go at recreating what I've seen on other sites. I am slightly concerned that the whole lot will explode when I switch it on, but it's all part of the learning curve. At some point on the weekend expect to see pictures of the whole lot in pieces.

All the electrics should be fine, and I've got an FX4 running on the axolotl tank, so I should be ok setting that up. Regardless of the amount of super glue & silicone I've used, I'm still expecting the water pressure to break the manifold, so it should be quite exciting when I switch things on.
I have my usual safety precautions already in place - letting a friend know that if I don't email or text them by a certain time then it may be worth some minor panic, so I may have to extend that to getting them to come over with plenty of towels and a wet/dry vac to help me clear up the mess. 

It's still a work in progress, but nearly done.
It's currently cycling while I grow more algae on the remaining rocks in a tank on the windowsill.
The river manifold isn't running while I cycle, mainly to give some of the plants a chance to root well enough not to get swept away later. The flow at the back of the tank won't be quite as strong as the rest of the tank, so I'm hoping that everything will be ok. If not, then I'll just take all the plants out and put more wood & rocks in.
I've got 2 sets of bright lights on the tank to help with algae growth.
My biggest problem now is narrowing down the final list of fish. 

Lol took me a while to spot the Otto... wasn't looking for that!

Tank looks great Littlefish, have you tested the manifold?
It will look brilliant when the rocks are added.
