per gallon,his first post says 15ml per gallon to fight the root rot.10 ml is for preventive maintenance.And yes US gallon

Makes sense if tis is the case Myke!!

I agree with mike, the container should have some holes around, the inner container, like a net cup, that's my opinion.
I personally don't recommend any chemicals do clean the system, can get into the plastic and take really long to release, some times you even smell it after some time. I used before some products from grow shops to clean the systems, and honestly, wasn't worth it.
How i wash my systems? Water + Sponge +Patience (every corner), the tubes i use a bottle cleaner, you can adapt it to go any longer you want to.

I dont have air stones in res, but I believe pump for chiller make the res recirculating should make enough oxygen.No worries man.
Not sure about ebb as I’ve never tried it. Could your root temps be high in between flood cycles?
Also do you oxygenate the res for your ebb? I’m not sure if this is a done thing with ebb? But I would imagine it would have nothing but benefits.
Itl keep the solution from settling, give you highly oxygenated water and keep res water healthier for longer.
I grow dwc. And aim for lots of fine bubbles from my air stones.
I’ve used h2o2 for root rot and did not help I’m my case.
Personally I think You shouldn’t need to use it as a preventative if you have temps under control and plenty of fine bubbles with no light leaks.
Although it’s not ideal for your bennies and general health of the plant, using a res with chlorinated tap water for a week here or there helps keep roots nice and white......
Just some food for thought. Good luck!
It could be high temps water in the buckets in between flood cycles.
I just set the bucket higher to make sure there is no much water in the buckets when water drain.
Thanks again
cheers
Thanks again for the feedback
does that mean if I use H2o2, I should not put anything organic in res? my base nutes are synthetic(GH maxi), but my kelps, silica, fulvic Acids,
Humic Acids, Amino Acids are organic. Im not sure if its ok to use it with H2o2
This is what I use: https://www.kelp4less.com/shop/powder-extreme-blend/

@futuretech thanks for the feedbackI see there 3 Issues, the first one is a nutrient lock, caused by the second one that is big PH fluctuations, the third issue is overwatering, so possibly there is lack of oxygen, you maybe need to make the watering timer with longer breaks.
Now the PH dropping was possibly caused by an excess of K (Potassium), and that happens often on F&D and drip systems cause of salt build-up, make sure to clean the whole system on the next run, including the tubes.
Anyway i don't know how much 0,8ec from your meter converts to PPM, but i would do 1 flush, i would start by changing all the water to 150PPM or ROI if possible for 12h, then take all that out and change once again and keep it running on a steady ph for 24h.
Make sure to figure out why the plants show overwatering symptoms, possibly lack of oxygen is due to watering after watering without time for the roots to breathe.
I did flush it with H2o2 for two days, roots zone look much cleaner than before, but i dont see any recover from plants.
I flood four times a day( only when lights on) for 15mins. I use this setup for few years without any problems.
My friends use the same system even flood more than me. no over water symptoms. so I really dont know why.
Do you think stagnate water left in the buckets in between floods could cause overwater symptoms?
cheers
Thnaks for the feedback
I flood four time a day, just cut it to two.
lets see how it works.
cheers
Thanks for the feedback.
I thought water left in the buckets would be live saver for plants if flood controller broke...
I just set the buckets higher, that way not much water left in the buckets in between floods.
cheers
Yes the inner buckets sure have holes, but when water drain it still have some left in the outer buckets.I agree with mike, the container should have some holes around, the inner container, like a net cup, that's my opinion.

thanks for sharing how you clean the system....actually I have hard time figure out how to clean the tubes.

I flush with H2o2 for two days.
roots look much cleaner now, but plants does not have sign of recover.
Ph still drop 0.1 in 24 hrs
Even one branch die again today.
I change out res and put H2o2 and some nutes today.
also set the buckets high
Here are some pics of roots and plans

I have another veg room with the same ebb system.
PH drop from 5.7 to 4.7 in five days, but I dont see anything wrong with the plants.(leaf are green and roots are white)
EC also go up form 1.0 to 1.3
waht does that mean?
I change out the res with fresh nute.
I was sitting there to observe it flood.
Ph 5.8 EC 0.95 before the flood, after one flood PH drop to 5.75, EC raise to 1.0
Any feedback are welcome
cheers

Not familiar with this system but I am with hydroton.It dries quickly and having water in the bottom of the drain bucket is a must.Think of Fand D trays they have water in the grooves all the time this where the roots live.
I think your problem is not feeding enough times in a day.You have to have water sitting in the bottom,your roots are there it just needs to be replaced way more often so it doesnt heat up.

You can't use H2o2 with any kind of organics. It kills em off and renders them useless. The point in the H2o2 is to kill off ALL the bacteria -good and bad.
Did you rinse everything including the pots/hydroton/roots or just put new water in the system? Thats the only reason I can see the EC jumping up so high, so quick after only 1 flood minutes later is if you didnt rinse everything before putting in new water in the system. Root rot will make your pH dive very quickly.
If you cleaned em out and rinsed everything real good like I mentioned, you shouldnt have that brown nasty sludge in the bottom of your bucket still like seen in the last pic you posted. It looks just as cruddy as the pic you showed on day one to be honest.
You cant really half step anything here. You have to do every step I listed or my advice wont be helpful to you at all.

I thought plants dont need water during light off, but I never done top feed before.
I believe there is pretty high chance its water left in the bottom cause root rot.
I set the buckets higher so there is less water in the bottom of buckets.
Do you see over water sign in my pic?
I actually cut it to flood only twice a day during light on.
I really have no idea what my system really is. Ebb and grow? its like ebb and flow, but instead flood to the tray. it flood to the buckets
this the system i use: http://www.hydromart.com.au/super-pro-hydroponic-system
cheers
I see...I think I miss the cleaning part in the buckets...I only clean the res tank and refill water with H2o2
I thought it was rise the buckets with H2o2....poor me
@HydroRed thanks again for the clear out the steps for me
on the No.29 post on this thread its my another veg room. Not the one I post with pics before.
roots are clean plants look fine, but PH go down.
Do you know what could cause this problem?
cheers

Hydroponics is hydroponics,roots need to be living in cool oxygenated water.They can never dry out.How long does the pump run on ea cycle?If its only minutes then
put your timer on to flood once an hour,your plants will start to look better in no time.
I had a look at your system,very odd.It appears to have one pump to flood and another to drain??
With all the pails at the same level and the res the same
edit to add your system looks different,not sure what the idea is.Maybe someone here understands it.

I was also wondering how the roots get any air inside those buckets. I'm not sold on that type of system at all.

Do you have a bubbler or a venturi in the master res? If not, Id add a nice one since that will be effectively what feeds all the other buckets and there isnt anything to add D.O. to the water since theres no drip/waterfall effect anywhere throughout the system to add it naturally. I have a flood and drain tray that I dont keep a bubbler in the res because the waterfall action of the drain portion of the setup keeps the D.O. naturally in the water every time it floods and drains.

Is the rainbow coloured link not showing up? maybe you have sigs turned off.

Adding a bubbler to your res will make your water more oxygenated and keep things stirring up. Have you ever seen a fish tank that has minimal oxygen? Doesn’t take long to see alge!
