Rocks, slate, wood

[777james777]

I have had a tank now for almost 2 years.

160 litres and home to cardinal tetras honey gourami, rummy nose and a large shrimp.

I have lots of plants and some ornaments (the plastic fake kind)

I REALLY want some real rocks or wood or slate, something more real. But im
Concerned what they do to the water,

any advice?

I have used slate for many years with no affect on the water quality. It is great for breeding Angels. Rocks in general need to be checked first to ensure they don't alter the water. Granite is harmless. You can take a rock and pour some vinegar on it to see if there is any fizz. If so, pass it up. Get something like Mopani wood for your tank.

If you get slate just check it doesn't have pyrite crystals in it, otherwise it is a normally safe chose. Some slates have a lot of pyrite crystals in them. I typically like metamorphic rocks in general as they have nicer shapes.

I have little slate "bridges" I made in two little betta tanks, and there haven't been any problems. This slate is from a local quarry that stopped being used in the early 1900s!! That makes it very easy to find small, tank-friendly specimens. I DID, though, boil them in water just in case.

How would I know what pyrite crystals are, Iv seen quite a bit about not putting slate in

All I’m seeing on google and YouTube is not to get this wood as it causes issues. There’s a lot of mixed views when it come to tanks im
