I've been tampering with tanks for some time now. Through this
newsgroup I have also picked up lots of tips.
One thing I haven't seen mentioned as a quick easy cheap source of co2
is Club Soda. I seems to me that a dash in your tank each day would add
the co2 the plants need. Club Soda is just carbonated water right.? If
anyone has any thoughts on this please reply.


It may work, but be aware that club soda contains potassium carbonate, which
will affect your water hardness, and may even *raise* PH.
