Med, I do have the 90 with the hole in it (vacuum break) pointed down, I'm gonna put my pump in the way I had it (the correct way according to the manual), right now I've got the intake pointed down and it shuts off like it should, I'll try it once more their way and see what happens. and thanks for the time.db,jus jumpin in here late,but did you say you were having probs without the check valve,or just pissed you didn't get one?i ve got 2 systems with the delay and no check valves and have had no probs,also do you have the 90 elbow with a hole in it on the fill pump exit from the res? to lazy to reread thread ma bad
he did it causes issue with bennysodd I could have sworn jd said not to put airstones in your res :/
that is the best idea. i am talking from experience i figured that an airstone would be bitchen to get more DO in the water. it didnt make a difference in growth, and my root growth was slowed i asked my friend who like i said is a 3rd generation grower he explained how the airstone and the super oxygenated water was killing off my beenys from root excellerator and great white so that is why my roots were suffering. if you dont use bennys then the airstone is fine and probably beneficial depending on your setup. if you do use bennys then you need to pick one or the other otherwise you are wasting your moneyim starting to think so to im going to have my buddy shut off his and see.
i have never experienced this. i add my beenies and my sweeteners partially to feed them mainly because i feel it makes a very big difference in the aroma and flavor of my bud. never had foam issue can we see pictures lol im curious as to what this looks like im picturing like a shaken up soda opening and foaming everywhere or like baking soda and vinegarthe only thing I've read is to not feed the bennies in res, thats where the foam may come from.
like i said i have nothing to back it up except for my own experience and hearing this from very experienced growers with 20 years experiencebeneficial bacteria are aerobic and without o2 will die, bad bacteria in anaerobic I'll always run an airstone in res.http://www.google.com/url?sa=t&source=web&cd=1&sqi=2&ved=0CCQQFjAA&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FAnaerobic&rct=j&q=anaerobic&ei=odU8TrrlDIO1sQKXiuUz&usg=AFQjCNGhf5NPF5bKqP0nIicnQGTguUC7Rw&sig2=ZIg4Da2vI-BFK6rV4ABzMA&cad=rja
