these r the two item that I have & use with no problems. I add 4-5gal bottles(40gal total) in the tote. It fill up to 3/4 of the way up with hydroton in the tray. i beleive i have 250gph pump to fill tray up. but i did notice with no hydroton it only filled up about 1/4 the ways & had issues. I would invest in ph meter & ppm meter, costly at first but it was one of the first things I bought. You'll need temp guage to make sure its not to hot or cold. need a fan to make stock stonger & all ur nuites.
