I was going to ask how long of a drive but I saw your answer. I exited out and when I came back to respond it must have kept it that’s my fault. I have one black lava rock I added to my tank a while ago and one piece of my life rock in there. I also got some bio cube type that is in a bag. That’s good to know, I’ll be conscious of it thanks! It’s just going to be and my dog on the trip so I’ll have the cooler up front to keep an eye on it and avoid it moving too much. Curious how far up I should fill the cooler though, all the way to the top or leave some room? My concern with leaving room is that the water will swash around a bit more than full.
