Hi to all,
My question is what kind of gravel is good for fishes in the tank. DO gravel matter a lot to fishes. I am using the golden sand as my gravel, it got lots of sea shells in it(smalll ones), the seller was saying it comes directly from sea shores. Also what kind of rocks are good for aquarium as i want to make some artificial hidden places for my fishes.
Heard a lot that rock also decays in the water creating dusts
Hi,
I can't answer all your questions, but I'll give it a try lol.
I'm not too sure, but I think most of the time substrate is just a matter of personal tastes. Some people have it, some people don't.
As for the 'golden sand', what sort of aquarium are you setting up? If you're setting up a freshwater aquarium, then you may find that the 'golden sand' has a lot of salt in it, which would affect freshwater fish (with the except of mollies and brackish species)
Now rocks in aquariums are usually safer if you buy them from aquatic stores. The main reason for this is that rocks outside, say for instance: from the ground, could carry a number of toxic if not lethal nasties that you wouldn't be wanting to put in your aquarium eg. pesticides etc
Another reason is that, rocks might have the right properties to make your tank ph swing wildy. Say you have a tank with a PH of 6.5 - 7. Brilliant

but what happens if you were to add a 'soft' rock with chalk or lime in it? you would see the rock (over a long time) dissolve and before you'd see that happening, you'd more than likely see your PH climb up to 8 or more (although I think anything over 8 is a bit extreme for FW. Although I could be wrong on that if anyone wants to correct me)
The best way to test if you have 'soft' rock is to pour some vinegar on it and see if it starts bubbling and fizzing. If it does, then it's unsuitable for your aquarium.
If you really want to add rocks from your garden etc, then I would boil them for a long long time. I would suggest baking them, but I had a rock explode last time I put one in the oven
As for amount required for your aquarium.. this depends on how thick you want your substrate. Anything from 1" to 2" is sufficient for your average aquarium
Hope this helps
