Re: [GSAS-Member] pH and gender

["A JACOBSON" <amjacobson52@msn.com>]

So that's my problem -- my tanks are all acidic, and my Endlers are almost all 
males.  So how do I gently boost the Ph in my EXTREMELY simple Endler's tank (2 
or 3 gallons, water sprite & hornwort, undergravel filter, & clip on 
full-spectrum incandescent for both heat & light.)  It's been going without 
anything but water changes for several months, so it's definitely on the acidic 
side.  Since it is such a small tank, I want to GENTLY nudge the ph, rather 
than make an abrupt change.

I'd be willing to set up a 10 or 20 gallon for them, if that's what necessary 
to make them produce more females.

  Fran, if you get down to Seattle give me a call (206-938-1583) and we can 
  arrange for you to pick up some females.
  The Endlers I have seem to be tough little buggers. They thrive on neglect. 
  I"ve never had any die.Maybe it's the flouride and other additives in 
  Seattle water!
