res cleaning with ebb and flow

So I'm just wanting to know how clean do I need to get it between changes. Using hollands secret keep temp at about 65-70 usually on the low side of that and use two air stones and a water circulator so it stays healthy. Just pain in the was to take a fifty gallon res and put it in the shower to wash it. Can't take outside because have to be descrete about it. Is washing it with bleach necessary between res changes.

I clean my 50gal res's after every harvest using a utility sprayer from lowes that attaches to the shower head. It is designed for higher pressure than a normal shower head and works great. For when I do res changes while in flower I just empty using the pump and refill, no need to clean if you have control of the environment like it seems you have.

I only clean with bleach at the end of a grow. I changs res every week and I clean just with water. You want to make sure you use a lot of water to make sure all the bleach is gone. I have a 55 gal res and I use a pump to get water out of res so I don't have to take it out side. match

As he said pump it out.

Bleach is great because it sanitizes your reservoir even if you don't get everything out. I use every time commercially. Rinse out well if you must pump it out flood the tub multiple times scrubbing the edges to ensure all bleach is gone.

use a pummp and hose to empty to drain... pnce you empty. take the res out bro..

fill it up let soak with bleach over night, then empty in morning and scrub down sides to get rod of residue, rinse empty and you are good to go bro...
