Thanks to all for the excellent responses - I have set the CO2 bottle
in
place and is bubbling away - new stronger lights have been ordered.

I suppose my only remaining puzzle is why a company like Juwel (my
tank
is
a
Juwel Rio 240) include carbon impregnated pads in their filter systems
if
they are detrimental to good plant growth and aquarium conditions
generally?


Carbon is good in a fish-only tank, as it removes a lot of toxic
substances
from the water. It's only a problem in tanks with plants or live corals.

Nay .... it isn't good even in a fish tank full time. It still removes
all
sorts of traces fish need.

It just makes the tank clear and makes them money.

It removes some trace elements, which is bad.
But it also removes traces of cleaning chemicals, paint fumes, etc.

Sometimes it helps, sometimes not.

I usually don't use it, but I do put carbon in the filters if I do any
painting or heavy-duty cleaning around the house.
