No, I use silica and it holds stable. Ph adjusters, especially organic ones can drift as it breaks down in the resivoir. But once you balance the ph with nutrients and silica it shouldnt drift unless you are pumping air through it or using cheap nutrients or organic ph adjusters.Thanks. I think it may be the liquid silicon I put in the water on there.
I make a fresh resivoir every other day and over the course of 48 hrs it doesnt drift 0.1. Nothing.
I use quality nutrients, botanicare specifically and I dont use an airstone. I've always found pumping air into a res made ph drift and since I stopped years ago I havent noticed any I'll effect.
If my res was sitting for several days or a week then it's a different story.
Would you use a recirculating submersible pump if going longer?
Thanks. I am not using the airstone in it. I have not set up the reservoir yet. The autopots recommend hand watering for like 2-3 weeks then putting it on the reservoir. While hand watering I have noticed that after I mix in the gh calmag with the gh silicon then use gh ph down to get it down to like 6.2 then when I test it the next day to use that day it usually has gone up by like .5 on there.
Wait your afraid of pumping dirty air into your solution?
It's the same air you breath every day all day. I can't see how the air would need filtering first.
Besides would the stones not be a sort of filter?
I've found when I was using additives I had nothing but trouble with ph fluxes. Sometimes major fluxes and not always up or down. I stopped using additi e's and use only the base nutes. Got my rez temps steady at 65-68f. Haven't had a problem besides yellow spots I assume are light burn now from spraying them down hour before lights out.
Silica does not want to dissolve in anything but pure water. I've not much experience with it but it's to be added only to pure water first before calmag so it dissolves completely.
DWC is a different animal... cant really comment on it as I dont have enough experience with roots in just water. But theoretically I dont see why not if the water was flowing fast enough and there was enough churning and turbulence.Sorry Dbag not knocking the how or why you do waht ya do with filtered air comment.
In a recerc system I've seen ppl use stones but would the recirculation not oxygenate the water at least a bit?
Also I run dwc so these are just thoughts but with the rdwc could you on the feed side using gravety and a slope use bigger diameter pipe then say hang a bunch of objects ramdomly thru the first part if it Comming from rez to make a babbling brook kinda thing to airate the water?
Kinda like a waterfall
No i know I just have to look at my ceiling fans they get pretty dirty or my cars air filter but I mean you breath the same air so I would figure it's not doing any more harm putting said air into water for your plants.
Now mold in the room or potential for it that's another story. Although not all mold is bad mold lol
