new-ish to posting but been growing for years. i totally agree w/ birdx and do the same thing(fill 50 gal and have 4 airstones and water pump pulling from bottom and waterfalling back up top).
i also use the small boy w/ kdf85. i have chloramine water. i noticed almost immediate difference in veg growth. watered one w/ tap(that sat for cpl days) and one straight out of small boy. tap = continued as usual. small boy = took off. and have been more than happy ever since. solved a big problem for me, chloramines killing my microbes.
i use and re use home blend. coco, ewc, compost, plus about 15 amendments or so mix. so i am all about microbes. the small boy is an excellent pick up for the price. do get the kdf85 upgrade.
not to mention this water tastes better than any bottled water i have ever had. that is to say it has NO taste at all.
