Ok, finally took some pictures and got them uploaded to the net. This post might be lengthy but probably mostly pictures.
Charlie, with the shrimp tank, it was made in a way that it's a glass panel on a plastic frame. The plastic frame couldn't be removed without completely destroying the tank and being left with a glass pane. Attached to the frame was the annoying filter. Thankfully, it was not made all to well so it was not too difficult to simply saw it off.
I've gotten the flow under control, turns out there was a very effective switch that alters whether the flow comes out the top or the front, now most of the current is directed at the surface. Highly reccomend the eheim internal by the way, although only having it operating about a week I'm very happy so far. Breezy to set up and maintenance is simple for an internal. The flow adjuster is darned useful too.
Here it was a few weeks ago, as you can see the light is a no good yellow color and the premade filter made it difficult to scape.

The whole operation on the tank took about an hour all up, I lost my fine toothed saw so I had to use a larger toothed saw for logs and such which was not easy to say the least. I transferred the media across, took out the decor and did a large water change, then sawed the filter out and put in the new eheim internal. Here it was directly after the operation on Saturday:

Very foggy.
Here it is today, looks miles better than before and cleaning is a lot easier.
Happily, despite the massive changes there has been no spikes thus far! All things toxic come back a reassuring 0.
In other news, axolotls! Because they're cute and are doing very well at the moment.


The 90 liter has been heavily trimmed down as the plant were getting ridiculous, this is the most recent shot I have of the pre rescaled tank:
It was far more overgrown than that at the time of the rescape.
In that rescape I replace the airpump, switched the driftwood, plants, rocks and moss balls around and added some cryptocoryne species.
Here is a recent picture of it;

It's a lot less busy looking now and the fish are enjoying the extra space, also the kuhli loaches come out far more now than before the rescape despite less plant matter.
And finally in my little world is the progress on my new tank, the juwel vision 180. As mention a few posts earlier I got in some bags of aquasoil, which looks really nice. I haven't set up the tank yet but I am frequently planning and working on getting decor for it.
Here is a bag of aquasoil.
Sorry for rubbish quality of some of the pictures, phone is getting old and worn out.
