Best cleaner for flood tray that started getting green mold? PLain old soap? Bleach?

So at the end of a run, the tray started getting a little green mold going on... I fought it off but the last week or so I was unable to tend to the op so it has a good hold in the tray... So i wraped the op up and called it done... Now I need to clean up all the gear and wondered what is going to be effective enough to kill/stop the mold and leave me a clean & sterile tray without any ill effect for the next run...I know that bleach can leave a thin 'film' behind so I was trying to avoid that... and H202 might not be cost effective for cleaning purposes (the store bought stuff, not the 33% stuff)...Any suggestions?

Anyone know about the Ona Bleach stuff?

No one? I'm thinking of just going the bleach route and knowing I need to rinse, rinse, and then rinse some more...

The green stuff is algea, not mold. Harmless but ugly.
I would just wash with soapy water and wipe with bleach water and rinse.

Or use h202 and rinse

H2O2 is good and just plain, cheap, Clorox (sodium hyposulfate) bleach will do a great job.

Man, I would say very light water/bleach solution or H202. Get some gloves and a nice scrub brush and knock it out in 20 mins ! I have black trays and i haven't seen any "thin film" left behind. Also just for a heads up, i just started using a product called "Drip Clean" from house and garden. I add this to my res during feeding, it prevents salt build up in the roots, hoses, reservoir, etc . You might want to try that out.
