ok, so two weeks ago, i built a stand for my LR in the DT to give it a fuller look. today, i installed a second return pump and plumbed it up, and over the side of the tank, then down behind the rock in the tank. almost down the the bottom to create more flow and eliminate dead spots behind the rocks. i also did this with my other return pump too. now i have tons of bubbles in the tank. at first i had huge bubbles coming out from under the rocks from the returns, so i plugged up the air hole that i drilled (the hole is so the siphon breaks incase of power outages). that got rid of the huge bubbles but now i have real little ones. my sump is not running low, so the pumps arent sucking in air, and the overflows, overflow into a different chamber that the pumps, so its not bubbles from water splashing. so what else is there?
