Dimming Ballast/Snail Dip
Hi,
I have some questions. First, I want to upgrade my hood to use a 4 lamp T-8
electronic ballast. Looking through the Grainger catalog, I see some that
are dimmable. What do these do to the life expectancy of the bulbs/ballast,
and how do you wire a dimmer to the ballast to control it? I have my hood on
a timer and it turns on/off by itself but I'm sure my fish don't appreciate
the flash of light in the morning. Can you wire a device to dim on/off
automatically? Next, I've looked through the archives and FAQ and have found
treatments to kill/reduce snails on plants. One method is to use potassium
permangate, but the stores I go to don't carry it. The other is to use a
dilution of bleach. What is the ideal concentration/time to eradicate snails
and their eggs on plants before adding them to the tank? Thanks for the
advice!
