“Because you can only do water changes of 25 to 30%, with a large tank you can't gravel vac all of it. The Ehemin vac pro finishes it off without taking excess water out and cleans the poop out of the substrate extremely well. Very happy with the perchase”
“This is perfect for both gravel and sand, especially sand which is a pain with other vacs which pick up too much sand. The Eheim doesn’t and it’s quick and easy to use between water changes”
“I really enjoyed this purchase; I have a 180L tank so cleaning it frequently would be a huge job but this allows me to get the gunk out while saving a lot of the good bacteria. Batteries seemed to die kind of fast but also could have been because they were the default that came with it”
