Isn't the media suppose to bubble if it's not good for pH?

Comment by Jim Fisk on July 25, 2017 at 7:00am

I get my granite directly from the quarry so there is very little chance of contamination form say limestone. Just a thought.

well I'm S.O.L on the media I chose. I had checked some and it did not bubble on my test now I go through my grow beds and get really selective on rock and boom found the ones I was told were not in the gravel. The cost is not much the time and energy to dig it up. Time to keep looking for a source that knows what they truly have on the lot. I have low spots in the drive anyway.

thanks guys

The best I can come up with on hydroxides vs bicarbonates is the bicarbonates buffer the system and slows pH changes. My system is the same size as Anthony's and once they're established will maintain a more constant level of pH. In Anthony's case he doesn't need to raise pH so he'll need to use something to add potassium but not buffer the system. Check this out:

No one should be scolding anyone for they're choices here but rather advising.

I'm not familiar with Maxicrop but even after your system cycles you'll need to add Epsom Salt (magnesium sulphate), potassium sulphate, calcium, and iron chelate to your system on a regular basis so you could start there. You could use lime for calcium and potassium hydroxide but those will raise your pH and it looks like you don't need to do that. Check out these videos for more info:

I probably should have recommended these to you a while back. There's lots of great info here.

Hay can anybody tell why maxicrop seaweed with iron is not good for food crops please. Is there another product I can use to give my plants a boost as I'm waiting on nitates to show up

Comment by Anthony Payne on July 19, 2017 at 3:30pm

Thanks guys, Jim just ordered the Ph down will give it a go and see what happens.

Comment by Jim Fisk on July 19, 2017 at 12:13pm

Anthony I got a bottle of PH Down from this sight back when we were starting up and it worked great in our @ 2400g system. Been using ashes from the GH wood stove since it was established and tends down on it's own as all seem to do. It should be here somewhere:

OK I have been cycling since 7-1. I added 3 oz ammonia system went to 3.5 ppm and now it's 0.00 ppm, no nitrites, no nitrates. My ph coming from the well is 8.2 used a gallon of vinegar did nothing. thinking of getting muratic acid now. Questions As my system develops will the Ph go down? Does the high Ph make the bacteria grow slower or not at all?
