I use RW with an ounce of consan 20 in it to keep the algae down..Indeed it starts to smell like it has fish in it if I dont..The tank holds 5 gallons so its negligible amount to the phrags but not any slime that might be alive..I change out the water weekly for fresh too ...I have an updated pic ..
the phrags you can see them growing already
the andean tears has put on a full half an inch in leaf span since I got them..
notice the temp is 71 and humidity 65% ..cool and moist
the frog fogger
is now a PHRAG phogger
CAUTION!!!
I would like to add that anytime you place electrical devices in close proximity to water ,you need protected circuits, I.E. protected power strips with a breaker or a GFI wall outlet in case water gets to it you want it to shut down. This is very important for your safety as we all know water and electricity do not mix well...The power is 4 ft away from all this but its still a hazard if not properly protected.
