So, filthy water

I am going to have to change to twice weekly water changes, if I don't get the hydroponics going soon.  They get up to 100ish ppm of nitrate in a week.  They eat so much.  They clog several filters.


There is some pretty significant differentiation by size of these kids.  Some are over 6", some are about 5".  They are all starting to get beat up from being in the small, scratchy space I've given them.  Unfortunately, as this past weekend has shown, I can't be sure that the outside will be warm enough for them right away.  We had over an inch of snow, and winds of 80km/h for the weekend.  That creates some interesting design challenges.
Gave a presentation on the weekend about my setup.
