Hi razor,
Well, i actuall like sand better myself but, have all gravel
The benifits of sand are that it is compact and won't let in things like excess fish food.........the bad thing is the water changes, if you use a siphon which will probally take up some sand. >
One more thing there is if you use sand and plan on using a UGF(
) you won't be able to because the grains will go in between the grate.
The benefits of gravel are that you can choose from a variety of colors,probally lets the water flow through easilier which then the "good" bacteria may help with biological filtration whch will help before it flows into the filter.One of the bad things is that it will let in food into the crannies and the cause it to decay and foul your water.Yet again another bad point in gravel is if you have fish that dig because sometimes the eat the gravel and it either gets in their organs or it has them unable to eat other food and eventually die.
Hopefuly that was right about the organ thing but, i think it is :
Tell me if you disagree
* Both I think are good with plants unless you are using an UGF.
So it is really a matter of taste
Good luck,
Daniel
