Question How to clean used gravel?

ok - STILL workin on my bargain 30gal - came with gravel...
what's the best way to clean the rocks?

I wondered if just a hot rinsing is enuf, or is there more I should
do to make the gravel safe for my new tank setup? Never know
what all went on in the previous tank (sickness/bacteria etc).

I imagine these same questions get posted over & over by newbs -
but I searched & didn't come up with these particular answers.

Any help appreciated!

I would put it in the bath tub or sink and poor boiling water over it a couple of times. That should kill any uckys it might have.

Kindest Regards,

Keeping fish its not a hobby it is a passion!

I have a 55 gallon, 40 gallon, 29 gallon, 20 gallon tank, 5 gallon , and a 2.5 gallon all with real plants.

please don't worry about asking :)
i like calmwaters idea,i think it's good.
you could always use bleach( i wouldn't know the ratio of bleach and water though )
making sure you really rinsed it,and then use a dechlorinator after.
i hope this helps,and have fun setting up the new tank.
what's going in there ?

all the above advice is good ;D
i normally just wash it with hot-boiling water when i got my used tank [my 20gal]
and my fishies are swimming all happy and dandy ;D
just use the dechlorinator and make sure they are rinsed off nice and good ;D

do you have any plans for fishies?

use the same method and you will get some good results. but since your gravel is used i would let it completely dry out after you wash it to ensure everything is dead. Money

Once again ty for all the advice!

I have an idea about a coupla oscars (because I raised them before) -
would that 30 (technically 29 gal) be a good starter size? I know I eventually had to move mine to
a 55 gal because they grew so big.

Started with my 10 gal & I now own 7 tanks! lol - local town-wide garage sales...also picked up a few 2-$3 bits boxes (now have 3 gravel vacs) & 5 air pumps & 3 filters - decorations - all sortsa fishy things etc... is fun & CHEAP! So... many cool things passed on (one woman's junk is another ones treasure)! lmao

Great time for this question

Thats super timing..
I to have some Rock... that need a good cleaning..
I purchased a tank about 2 weeks ago...
and the rock fills up a 5 gallon bucket... well that
what I have it stored in.. I am sure the Rock is still wet
down in the near bottom of that bucket....
so I to have been thinking as to how to clean it..
I am glad that you asked this question.....
only reason that I have not started to clean this
Rock yet is .... well there are finer pieces of WHITE
shell or Rock or somthing mixed in with the Natural
Color rock.. I dont like that look.. I actually thougt about
just throwing it out.. but I guess I will strain it some how
to get out the little white ones.. LOL.. sounds like a chore to
me... but oh well.. Great POST.... :o)

i would avoid bleach for rinsing gravel... some rocks may be porous and absorb the bleach, in which case turns the gravel in an aquarium killer. Boiling water, then a long time baking in the sun is what I do.
