Tank maintenance shouldn't be a huge task. Small water changes do nothing to maintain clean water conditions for the fish and plants. If you're getting the gear out to change the water, then change it. A 30 gallon tank needs a 50 percent water change weekly. Small water changes leave a lot of dissolved wastes in the tank to stress the fish. If your fish are acting abnormally, you're not taking care of the water, it's that simple.
Everything that goes in to the tank eventually dissolves in the water. If you remove the water, you remove what's in it. So, don't spend time vacuuming, just remove the water and replace it with fresh, treated tap water. This alone will keep the chemistry stable and safe for the tank inhabitants.
By removing and replacing a lot of the water and doing this often, your fish and plants will be much healthier. Pretty easy.
