Pool Shock, Wanna check before I throw this in my REZ!!!

Alright so Im at home depot for something completely unrelated and I remember last second that I wanted to pick up some pool shock as I heard its part of a DIY clean rez recipe. Thing is when I get home I look up the recipe and Im not positive I picked out the right pool shock, so I wanted to check with RIU before I toss it in. The kind I have is called Pool Time shock plus 4-in-1 pool shock, says its not gonna raise my pH and that the active ingredient is Sodium dichlora-s-triazinetrione 58.2% and other Ing 41.8% I thought it was supposed to have calcium in it? and 41% OTHER SHIT? Im a little wary to throw this in. Also if it turns out to be the right one tespoon/ a gallon diluted sound bout right??? Shit I need help....-S0uP



Edit. This is for preventative maintenance BTW my rez Is looking healthy as well as my roots but my temps stay from 69-72 and I wanna keep it as sterile as I can before there is a problem so I thought pool shock at a low dose a good option. If there are horror stories out there I wanna know...

pool shock is nothing but chlorine in concentrated amounts and mostly salt. I don't suggest it but I haven't read or tried it. The best thing you can do is use a beneficial act tea. There is a sticky in the DWC forum. I can shock my pool with Expensive "shock" or just add lots of Chlorine.

^^^Thanks, I should have mentioned that Im not gonna go down the bennie road, Ive done the research and prefer just to keep a sterile rez until I upgrade to a bigger ebb and flow system (My current rez is only 20g but Ill be adding to a 60g soon). I have heard of people using Pool Shock with success??? No rush on this just dont wanna continue using H2o2 when there something cheaper and MORE effective. -S0uP

why not the Bennies. Man its cheap and it works < no Chems and it last longer and cheaper.

The kind of pool shock that works best in hydro is Calcium Hypochlorite, not Sodium dichlora-s-triazinetrione. The calcium is used by the plants where the sodium just poisons them. Some people, including me in the past, have succesfully used Pond Zyme which is enzymes that keep the rez clear by digesting dead organic matter. I use a product called Down Under HF (HydroSparkle DNF in Canada). Down Under HF is similar to the Pond Zyme with the added benefit of preventing the growth of the single-celled pathogens that cause root rot.

I have heard great things about pond zyme. almost forgot.

yes-

pool shock is calcium hypochlorite and is fine. same stuff as clear rez. i used to use it but don't do water culture lately and have forgotten the ratio i ran it at. i wanna say around 5 ppm.

tri or dichlor is a different chem and i have never used it in the res. it contains an acid meant to bond to the chlorine molecule and prevent it from being stripped by sunlight, and a buffer.

i would stick with 1 ppm free chlorine residual. as a 1ppm concentration will kill all of most strains of pythium in 20minutes.

sodium hypochlorite (chlorox) has worked accepatably for me, in my cloner the last few runs. if you run a residual of 1ppm free chlorine you will never get over a few ppm sodium, which is fine.

that or you could just use white vinegar and pump that through the system for a couple hours. also you can take the res/buckets and hand clean it with dishwashing soap

Actually that dichlora-s-triazinetrione is another name for hydrochlorous acid. Hydrochlorous acid is the active ingredient in Ez clones clear rez product. I'm using aqua chem shock plus and it has the same active ingredient as clear rez or rez clear whatever its called. I think either will do the job. I have pondzyme with barley and it doesn't really work that well in cloners or aeroponics. It works better in my soil grows.

Di- chlor 1 lb bag is the same stabilized chlorine as in a pool 3" tablet. The "other" ingredients also include but are not limited to cyanuric acid, 4 in one also often includes copper.

Where you buying the down under HF these days.. looks like the groovyhydro site is down

Got my hth pool shock and applied it yesterday. I've read 2 different ways to dose your rez. One 1 oz shock mixture to 5 gal of water and also 1 oz to 1 gal. Which is it? I went with 1 oz per 5 gal just to be safe.

I use the Pool shock at a rate of 1g per gallon. Then use 1ml of the mix per 5 gallons in the reservoir. https://www.icmag.com/ic/showthread.php?t=219683

Sorry to bump such an old thread but I'm just starting out using pool shock but took the advice of 1oz to 1 Gal, did the lower dose work for you? I've been running the higher dose for a week now and can't say I've seen any ill effects, just wondered if you upped your original dose or stuck with it? Thanks

Hi Budafinger,
The amount of available chlorine is varying between different brands. Jillandfarmgang started a thread on this topic and explained how to do the calculations:

///
I have some calcium hypochlorite (pool shock) that says 49% available chlorine. How much do I add to get 2 ppm of chlorine to a 100 gallon reservoir?

To figure for 2 ppm of TOTAL chlorine is simple.

Remember 1mg/L = 1 ppm

So 2 ppm would be 2 mg per liter of water.

100 gallons = 378.5 liters. So 378.5 x 2 = 757 mg

But its only 49 percent strong. So 757/.49=1545 mg or 1.545 g

I have not experienced any problems since I followed the recommended dosage. I hope that it will answer your question.
