So I have a gravel bottom and its a planted tank. I want to try and set up some type of spray to get under the gravel and mix it up since my filtration right now is twin HOB aquaclear 110s. I was thinking some kind of jet setup but I'm curious if anyone has done this with plants and if it completely messed them up and if anyone has done it on a tank that's already running? What types of pumps would I need to run it. It's a 6' long tank
