Most out there contains to much white silica pebbles
This is the biggest problem I have.
Thanks for the pointers I will try having a Google and see what i can come up with from your suggestion.

I do still wonder what ADA used to provide and also why they stopped like used in the Escape aquarium.

saw these at a local garden centre. I took a photo as I was looking for gravel to use on sand. They had two different sizes.
Thanks Harry; I can find some a little bigger I could pick through but smaller gravels is a struggle and larger stones too. A lot of what I've seen has the orange/speckled type colour hues I don't like too.

I've found some Icelandic boulders which might work but it still misses the gap out.

Am I the only one that looks for a stone that goes from a sand/gravel right upto the larger stones with the same type and maybe that's why ADA stopped the variety?

I guess I should voice my interest in this thread as well. I have been lurking in the background but share your frustration. I love pebbles and round stones and have been hunting for something that matches my beige sand, to no avail. I also have the Dennerle river pebbles, but was disappointed to see that they are quite cold in color and dont match as well as I had hoped with the beige. Im currently going through the bag picking out the brownest pebbles, but only about 2% are close enough.

This still leaves out the smaller sizes as well.

I have been looking at the gravel at https://www.flisbyab.se/produkter-ute/dekorsten-grus/sma-sackar
But these gravels have been reported to have a lot of limestone in them and has raised the PH for several aquarists.
Maybe it can be mitigated by picking out the white stones?
I ordered a bag of the biggest size a while back, but was disappointed. The pebbles are not very round, and they are a bright orange color.

Local gardening centers sell norwegian stone types in their pebble selections, which are very mottled and patterned stone that I find distracting in looks. Also only fairly big cobbles.

I quite like the look of "Scottish" Pebbles that seem to be sold from various retailers in the UK, they come in a variety of sizes and have nice uniform colors. Seems impossible to get them to Norway without paying some serious money for shipping a bunch of rocks though, and my common sense feels like having stones imported at great expense just to match a bit of sand is kind of ridiculous and a waste of money.
These might be too warm in color for your taste Andrew?

It's a shame you're not closer as I don't really like those and prefer the grey tones!

You might be surprised with the bigger, and even smaller ones there is also that mottling look from what I've seen.

You have to watch photos - you need to see them wet. Often then look fairly uniform different tones of grey/brown but they can end up very different colours wet! If you get enough you can pick through if you don't want any outliers. The unipac natural gravels match quite well for small stuff, but their idea of 'round' is a bit hit an miss.

Have you tried visiting your local garden/landscaping supplies?

The scottish cobbles I have seen online have had wet pictures and look like the colors I want, but getting them shipped over here would be difficult.

My local places all have very mottled stone types in their bags.

As did all the ones I saw, in reality they're not like that as @tam says and it's even more obvious by a long way when underwater.
They're a whole mixture of different stone types that over the countless years have drifted from various places.

I was unable to find anything that matched throughout size range easily so decided a contrasting look of a lighter coloured sand with darker stones is probably the way forward for me.
The ones I have seen seem to have people sourcing the larger stones from the seaside themselves.

Thanks @jaypeecee I've looked through the gravels before and had a couple of different types to look at, the problem was following that through with something bigger in size increments of the same size. I could get sand/gravel although most of it still contained quite a lot of white unless I went very dark, small stones that matched not so much and working my way upto big stones I just couldn't do so I gave up on this idea in the end.

Hi all,
And is that for aesthetic or other reasons?
Other reasons really. When I had some higher flow tanks (I had an excursion in Loricariids) <"I used coarser substrates"> and let the current sort them. If I kept Hill Stream loaches etc. I'd return to rounded gravel as a substrate. Have a look at @doylecolmdoyle <"loaches thread">.

I've mainly kept Apistogramma and Corydoras in recent years, and they both <"naturally feed from the sand">, and usually occur in <"habitats with fine substrates">.

I also have <"structural" leaf litter"> in the tanks, so sand is just so much easier to manage, with the leaf fragments etc sitting on the top of the sand. I keep Asellus and MTS in the tanks as "tank janitors".

I'm pretty sure that gravel vacuuming isn't good for any substrate and it isn't an activity that I'm going to engage in. If I had gravel I would need to find a new range of organisms that would perform that janitorial role in among the gravel fragments.

Gravel is my second favourite substrate (after uncapped dirt), I've always loved how sediment collects within the gravel - always has aided organisms in my tanks to thrive. Only recently moved to sand, and in the next tank I will be using gravel and sand in a 70/30 split. I don't like pure sand tanks.
