I have a 13.5 evo which is easy as can be to do water changes but the 55 Gal can be a pain. Do you guys just fill 2/3 5 Gallon buckets and change it that way and have 3 more for waste? I'm trying to make this as seamless as possible for me. Also any tips for getting the new water from the bucket on the floor to the aquarium on the stand? I bought a pump but it seems to be too strong and blows the new water into the tank kicking up sand. The other way I do it using a little container and scooping a little at a time but that creates a saltwater on the floor mess. Any tips would be much appreciated! I usually take out 10 gallons (2 buckets designated for dirty water) and then use 2- 5 Gallons with fresh water. Eventually will have to upgrade to at least 120 for my tang so I wanted to start being efficient now.
