It seems to me as slightly hard to moderately hard.Sorry, I thought I'd attached it!
I wouldn't get too hung up about this. At least the fish store warned that your water is too soft for guppies which suggests the person you were talking with actually knew what he was talking about. Many fish stroe staff don't even recognise hardness matters.So interestingly the website says it's 'slightly hard' and the general UK wide maps suggest the same, however I had already checked it this way and the one bit of consistent advice I have had from all the stores when questioning this exact issue (all within 10 miles of my house, two within 3 miles) is that the water in the area is actually soft which has been 'confirmed' by the store doing the test.

edit: Just seen your last post. That water is fine for neons and is indeed not fine for guppies
Personally I would keep them. Yes your tank is slighly smaller than ideal but it looks like a good environment. Adding floating plants would make it better for the tetras as they are naturally found in forests so are not great with bright lights. You can probably add another 3 or 4 as long as you jeep up with regular water changes (at least 50% per week. Are you aware of the nitrogen cycle? You can read more about it here https://www.fishforums.net/threads/cycling-your-new-fresh-water-tank-read-this-first.421488/Yes it's a subtle thing but the fact they did say that, and the fact they warned me off certain other types of tetra, is why I've gone with their advice on the neons but that's obviously not gone down well!
That is a good approach. My only nervousness is that 2 weeks seems very quick. It is worth investing in tests for at least ammonia and nitrite - even if its just for your own peace of mind.In terms of cycling it, ive used a combination of Dr Tim's Ammonium chloride and Tetra Safe Start over about 2 weeks, the LFS has run a few water tests on it, sent me away a couple of times then told me a few days sgo we were up and running. Again, will confirm when I get a better testing kit and won't add any more in for a while.
Shrimp or snails won't really thrive in soft water, you'd have to add calcium and other mineral supplements for both which would harden your water I believe so with neons this wouldn't really work IMO.For a tank this size, what's the thoughts on snails/shrimps? What's a good way to go? I've inherited a couple of very small baby snails that must have come on the plants but the store seems to think these aren't good news?
