DONT USE BLEACH. This was discussed in this thread *four* times before already, and determined every time to be not good for Hydroponics.
You can use a little bleach in a spray for a cleaner, but dont go filling up your 55 gallon rez with bleach water then draining it out.
To clean your 55 gallon rez, use a sponge and water. No need for any cleaners or chemicals of any sort. ALL of that nasty brown residue that you see there is just nutrients settling. Add a cheapy recirculating fishtank pump to help prevent that, they are $6 at a Hydro store.
Just drop it in and let it run! No hoses required.
I never clean, nor change my water, until after each harvest. Its always a top off and balance ppm to whatever week the plants are on, and if there's any "new" nutrients for that week they get the full 55 gallon dosage of that particular product then just continual balancing after that.................... Each 8 week harvest uses about 150 gallons of water for every 3000 watts of lighting. Pretty low usage and low waste...........
Hope this helps
