Re: [APD] Re: replacing existing gravel

The easiest to find HCL (muriatic acid) is swimming pool acid, which comes in one gallon plastic jugs. That is what I would use if I wanted to do this, but working with that acid is a real pain. Also, taking a breath of the fumes is extremely hazardous. Disposing of the used acid is also a problem, since it isn't supposed to be just dumped anywhere, and it will kill grass if you dump it on your yard. Our environmental regulations say we have to take it to a hazardous material dump to discard it. So, why not just buy quartz sand sold very cheaply as masonry sand by places like Home Depot? No acid should be needed then, because carbonates are not supposed to be in sand used to make concrete, and the sand is certified as free of carbonates. (If I am wrong about this, I hope someone corrects me.)

Then for acid wash, buy the HCL(muratic acid) used for bathroom cleaning
and pour some amount of it in the same tub.
The sand will fizzle. keep on pouring some amount & stirring till the
sand stops fizzling. Then again wash the sand with plain
water till the acid smell goes away.
While using acid, take due precautions to avoid acid burns,
e.g., use gloves, keep children away, don't shake vigorously and splash,etc.

For adding the new sand to the tank, get a large 1or 2 -inch diameter
attach a long (e.g..3 feet) plastic pipe to it and then position this into
the tank where you wan to introduce new gravel.
Then slowly pour new sand though
the funnel and slowly remove the pipe upwards,
so that new sand does not cause a storm!.
You can either remove some old gravel or just pour this new sand
where you think there are gaps in the old one.
I don't think there is any harm if you bury the old detritus under this new
gravel, and further it will act as fertilizer.

Hope it helps

To: aquatic-plants at actwin_com

I've been wanting to replace the large gravel in my biggest tank
and read a while back that play sand was a good plant base. I bought a
couple of 50 pound bags today at Lowes. Any thing I should do about
rinsing it (hints how?), and/or soaking it first? I am thinking of
removing the gravel in sections and replacing it with sand. The front
of the tank (44 gal. corner tank) has onyx sand and the clay plant base
stuff which name escapes me at the moment.. mixed with the gravel.
The tank is setup, has a bunch of swordtails, few corries, ottos,
and pleco, and a couple clown loaches who spend most of their time in the
hollow of the drift wood. I'm sure the corries and pleco will like the
change from gravel to sand. I've had trouble with the Pleco digging the
sand out of planters to hid in..
Plants, I have 10 Narrow-Leaf Dwarf Subulata along the front of
the glass, an Amazon Sword, a Needle Leaf Lud and a mystery plant in 3
small planting rocks, some floating Anacharis and Hornwort. This along
with a good size piece of drift wood take up most of the bottom of the
Any advice on replacing existing gravel with sand and any
I should be aware of? I expect the plants, corries and pleco will do
better. The current gravel has such large spaces between them the
swordtail fry hid in it.. Needless to say this is a major trap for food
and debris.
