Complete rebuild

Hi, I'm just posting this thread in case anyone is interested.
In January I started a heavily planted dirted Nano setup (30L) stocked with neocaridina.

About a month ago overnight almost every shrimp died to my absolute horror. Immediately I set about setting up a large plastic container and transferred the heater after cleaning it, and cleaned the filter thoroughly of any dead shrimp that may have been sucked into the inlet. I then had to completely dismantle my setup and painstakingly remove every dead shrimp from all the moss and roots of the epiphytes. Once I was satisfied I had enough I then started netting out as many shrimp that were still alive as I could but none of them were healthy or lively at all.

After the new hospital tank was up and running and stable I emptied the tank completely and got onto Gumtree for a cheap replacement. This time I decided to go with something relatively much larger and found a 70L tank going for £30. I bought it and got it home to find upon completing the watertight test that it was leaking all over.

I now had to completely dismantle a tank and rebuild it for the first time in nearly 30 years of fishkeeping. This was an absolute nightmare if I'm honest just because the plastic rim was hiding a whole plethora of serious issues with the front pane. I just ordered a new pane for a few quid and reassembled everything.

After a week I started rebuilding the hardscape and decided not to use dirt this time and just stuck to conventional gravel, sand and some aquascaping soil mixed in for the roots.
I also got rid of the hygrophila difformis because it was a nightmare in such a small set up due to the rate it grows. I'm going to use the hygrophila pinnatifida in place of it.

After planting and filling the tank I let it run using the old cycled filter and a 75W Jager I found in the shed for a few days, did my water checks and started introducing the shrimp a few a day.
After the three weeks in the hospital tank the shrimp were looking much much better, some females were berried and the colour of all of them had improved vastly.
Now they're looking happy and settled into the new tank. Once the vegetation has grown significantly I'll start adding a small number of ember tetra or galaxy Rasbora.

The cause of the die off remains a mystery but the most likely cause was a piece of vegetation or contaminated matter getting into the tank from a friend's garden who it turned out had recently used fungicide on their garden for blight.
