The fish I have a tetras (neon, flame, albino glowlight, yellow
phantom, rosy), silver shark, king tiger plec, moonlight gouramis and
of course clown loaches. The shark, loaches and plec have not shown
any signs of disease.

What additional filter are you using? The Juwel filter is rated for the
tank with a community of small fish, not a highly stocked tank with larger
fish.




The Juwel powerheads claim 1000l/h, standard on 240litre upwards, is enough
for tanks up to 500 litres, reading that of box with new powerhead. The
boxes tanks come in show angels, which need very clean water. If your
information is correct, I wish Juwel made that clear before we buy their
tanks. I am running 4 Juwels. My Rekord 96 was overstocked with over 60
platy fry from 2 mums, and the cycle held, low nitrate with 2 water changes
a week. My vision 260 has 8 clowns and 10 female platies, and I am thinking
of putting 150l/h powerhead on, as their huge treetrunk home has really
reduced the flow, although cycle is fine with low nitrate. I am very happy
with their filtration, even thinking of putting 2 on a new 6' or 7' tank for
the clowns soon. I know some like filtration that filters water 10 times an
hour, but I have the 6 times an hour on rekord 96 with 600l/h is fine,
enough movement for no algae. What do others think with Juwel tanks? Mary
