Shrimp need minerals more than fish salt. We tested shrimp GH/KH supplements and aquarium salts to find what belongs in a freshwater shrimp tank.

We tested five aquarium battery backups to see which keep air moving when the power dies, and which tank size each one really covers.

We tested freshwater algae treatments for slime, green water and hair algae. Here’s what clears a tank without costing you fish, shrimp or plants.

Five live stem plants compared for light, planting method and arrival condition, so you pick the one that suits your tank and your patience.

We tested freeze-dried daphnia for bettas, fry, and community tanks to find which one floats, gets eaten, and doesn’t cloud the water.

We dosed GH boosters in soft and RO water to find the ones that lift hardness predictably, for planted tanks, bettas and shrimp colonies.

The right sand keeps stems rooted without clouding the tank. We compare five picks on grain size, rinsing, color and how far a bag actually goes.

We tested six aquarium moonlights to find the ones with a genuinely dim, automatic night phase, from nano clips to submersible blue bars.

We tested seven goldfish foods for growth and picked the ones that put protein first, feed at depth, and keep water clear for tanks, ponds, and fry.

We tested sinking wafers, pellets, and granules to find the best food for corydoras, with picks for protein, budget, and picky eaters.
