Can anyone recommend some black aquarium gravel that's not sharp so bottom feeders done get cut, between 2mm and 5mm and preferably not gravel that's been coloured so in time will loose the black look.
Thanks tell what its like if you clean it soon, I found somewhere that stocked it and the got an email that I opened this aft saying from a supplier there was a 5% offer on but finished at 1pm today which I though had ended at weekend.I've got the Hugo Kamishi small grain (2-4mm) gravel in my tanks and it's pretty good. It's starting to look a little grey now though, but it has been in the tank a year and I haven't cleaned it recently.
I use this for my community tank with cories and clown loaches they are perfect. Colour doesn't fade,just as black as the 1st day I put it in.Had a look in today and saw the gravel and all things the bag had split and saw what had fallen out too fine.
Aquarium Volume CalculatorSorry to jump in and it has nothing to do with gravel but...... Going to be getting a bigger tank at the weekend. Got a bargain on a juwel 190. Now I have a aqua external pump which is 600L/H. Now I know I need to replace the water appox 4 times an hour but taking into account for substrate and wood etc etc do you think it will be ok? Works out I need 680 for 170l. How much space does all that stuff take up?
Maths was never my strong point. If you don't know which is the best forum to frequent where I would get an answer.......
even though I don't exclude them as apart from not being able to calculate for décor you do miss a lot of mass due to glass thickness substrate and headroom.You don't exclude the substrate and decor, you include them and base the filtration on the full tank volume.
I personally would never go for anything less than 6x the aquarium volume as it's always better to over filtrate rather than under. You can go up as high as you like though, my 110L for example has a 1200lph filter.

Anyway I have a 1200lph for my 40 gallon tank. and have the intake at one end of the tank and the spray bar at the other.
