With my water changes I was always having the addition of water mess up my gravel and decorations so I made a water diffuser out of things I had around the house and thought someone may like the idea so I thought I would post directions.
First you will need 2 three foot dowel rods and a shallow bucket. I used a bucket that I had from a hospital visit.
Second I drilled holes in the bottom of the bucket and 2 holes in each end/side to put the dowel rods through.
Then I set it on top of my tanks and I can add 5 gal
buckets of water without disturbing my decorations or gravel.
