tigger pods

[scooter413]

I have been culturing pods for about 4 months now and the Tigger pods and Tisbe pods had been doing well. But all of the sudden they are all dying and the water smells like rotten eggs. I have been adding new water once a week and doing water changes but it is getting worse. Changed one quart of water tonight and had a bazillion dead ones in the bottom. I am feeding them Nano and Tetraselmis live cultures but they are crashing very quickly as well. Any ideas of what could be going on.

I changed to Spirulina powder mixed with salt water this week due to the fact that I did not have a successfull phyto batch for two weeks now.

Water specs:

salinity 1.020
ph 7.8
low light
Use a rubber maid short tote for larger surface area
temp is 68-72
