You inferred. You don't seem to understand that distinction. I'm not here to educate you on reading comprehension. A rock in a bag of salt does indeed increase the weight of non-salts in that bag. If megacrop intentionally was putting rocks into bags I would hope, for their sake, they would be adding more than a pebble or two per bag lol. It's not like 1 pebble is a KG of salts. I don't even know why you're so hung up on this one thing. It was literally a single pebble on top of a 1" bottle cap.
You seem to want to focus on that instead of the potential for damage that it could have done to my system if I hadn't caught it... you know... the entire point of my post. Or the fact I wouldn't have caught it at all if their nutrients do what the company claims they do which is dissolve fully. I would have never had to run Cal/Mag through a bubble bag in the first place. I would have damaged my pumps and been left none the wiser as to the cause.
As for why I don't have filters I mix a fresh reservoir every 24 hours my reservoirs have lids where a hard line goes in. There's no way for anything to fall into, or climb into my reservoir. There's just enough room for air exchange so my pump doesn't cause pressure issues when it's on. Even with an inline filter, which I am not arguing is a good idea to protect my manifolds, there's still potential for damage to my pump. I don't think there's ever an instance where rocks in your nutrients is an acceptable thing.
What kind of pump were you using? Mine doesn't have a prefilter at all, which furthers your point that I should be using an inline filter. These floraflex manifolds require a lot of pressure I've been forced to use a 1/6hp pump to supply enough water.
I seen the pebble and I switched immediately.
edit: I ask what kind of pump you're using just out of curiosity if it had a pre-filter that stopped clogging of your sprayers? or an inline filter?
