River irrigation

hello fellow riu users- I am going to ask something and it might be a really stupid question but im going to ask anyway
- what if i used a pump to pressurise one of the miracle grow irrigation garden feeders with jacks 321 mixed in it to use in drain to waste to take advantage of a rivers thats near me incredible dissolved oxygen

How are you going to check for PH?

You could use a barrel, make your mix and pH, use a pump and the hose thingy.

thanks guys ph wasnt a great concern as the pump is going to be flushing the medium so ph shift shouldnt be all that great

I have found youthat if use 3-2-1 you shouldn't really have to pH. Maybe try a small batch and check the pH to know for sure.

I run all of the water for my plants through a Hydrologic Big Boy whole house filter. Two stages sediment and carbon. PPMs are there but are very low.

The rest of the house gets plain muni water. LOL
