Re: [APD] RE: cables and such

My opinions: Three substrates that I recommend are
SeaChem's Flourite, SeaChems' Onyx Sand, and CaribSea's

Each of these can be used by itself without supplemental
subtrates. Onxy Sand has a slight buffering capacity; the
other two do not. Eco-Complete is nearly black in water.
Onyx Sand is grey-slate colored. Fluorite comes in a
reddish color and in a darker version that is very popular.
You can check them out on the SeaChem.com web site and
Carib-sea.com (at Eco-complete is the last item on the 8th
page of the product catalogue on the website).

If you don't find them in your lfs, you can order them
online, and even with shipping it might be cheaper than
getting it from your lfs.

These substrates are porous (clay or clay-like material),
which is good for planted aquaria, unlike the epoxy-coated
gravel available in lfss in a wide variety of "natural" and
artificial colors.

If you use plain gravel/coarse sand (not epoxy coated, of
course) a thin layer of laterite mixed into the bottom inch
can help compensate for lack of porosity of the

It's the contest that started international competition in aquascaping
planted aquaria! AGA's 2004 Aquascaping Contest is open for entrees:


Novices and experts alike show their skills. Past winners have been
novices and experts, too. You can view all the entrees at The 5th AGA
Annual Convention. Details/Registration at www.aquatic-gardeners.org &
