That is correct. Same EXACT ingredient as EZ Clone Clear Rez that sells for $20 a QT.
Get your self a 1 lb bag of HTH Pool shock non PH buffered available online and most hardware stores (bought mine from Ace). Mix 1 GRAM (450 in the bag) per gallon of solution. Will make the SAME EXACT concentration fo the SAME EXACT product. $4 will make you 450 gallons of the stuff and will treat over 286,000 gallons of water !!
Should last you a little while ... Can you say markup ??
Been using this on all my clone machines and all my ebb and flow reservoirs now with great success. You use 1 OZ per 5 gallons. I actually make it a lot stronger at 24 grams per gallon then only have to use a teaspoon per 5 gallons. Works very well in both systems. Works better then H202. You need to reapply every 3 days to keep bacteria at bay. You can actually use much stronger doses if you like. City water is 1-5 PPM of chorine when you add this it only raises the PPM level of chlorine less then 1/2 a PPM. Very safe and very effective. Found my PH levels to be much more stable in my larger reservoirs compared to using 2 doses of 30% H202 per week. Its doing a better job of killing the nasties
$4 of this
Makes $2200 worth of this
