I couldn't see what the tank was like as prev owner was sheilding covid, I think he's eaten a little bit know as I fed him with my new fish! 2 clown loach 2 firemouths as they now seem to get along wellDid the tank he came from seem healthy? He looks well fed, maybe a bit stressed from the move?
Could you find out what he was fed on previously?
The 2 figures we need are 412.25 ppm (mg/l calcium carbonate) and 23.416 German degrees aka dH. It is very hard water.
I put in my postcode and it says thisIf you check the Anglican Water website you should be able to find it - they have a specific section for fish keeping.
For some reason I hadnt twigged there was a dH reading on there just missed it - if your home water is similar you may need to think about what to do as based on the shops post code its going to be challenging.
I live in SuffolkBeing next to the sea does not cause hard water. Redcar, for example, has soft water and that's on the coast. Hard water occurs where the water flows over limestone or chalk rocks at some point between falling as rain and coming out of the tap. The strip of coastline from Winterton-on-Sea through Great Yarmouth and Lowestoft down as far as Aldeburgh then inland as far as Rickinghall comes under Essex & Suffolk Water. Do you live in this strip?
