Aquarium Water Diffuser Compatible with Python Water Change Hook, Black

• GUARD YOUR LIVESTOCK — An open siphon intake is a worry when your fish or shrimp are nearby during a water change. This holder positions a sponge in the water-change flow path to guard against drawing them into the siphon, putting a barrier at the intake while you drain your tank rather than leaving you to watch an open intake as the water level falls.
• SPREAD THE REFILL — A fast refill sends fresh water back into your aquarium, but it does not need to arrive as one concentrated stream. This diffuser disperses incoming water from your aquarium water change hook into your tank, spreading the return flow during filling so your setup does more than direct a stream into the aquarium: it distributes that water as you bring the level back up.
• CLEAN BETWEEN CHANGES — After draining and refilling your aquarium, get to the sponge without leaving it tucked away inside the holder. The screw cap gives you access for cleaning after tank work and for replacing the sponge when it is time for a fresh one, so the part that sits in the water-change flow path stays accessible between maintenance sessions, not just when you first fit it.
• CHECK YOUR HOSE — Check your hose for a 1-inch (25.4 mm) inside diameter: that hose slides onto your aquarium water change hook and this holder to connect them for tank work.
• ONE WATER CHANGE WORKFLOW — Move from removing aquarium water to putting fresh water back with an accessory used for both jobs. The same holder serves during siphoning and filling, so your water-change setup has a role at each stage of the job, from drawing water out around your fish or shrimp to dispersing the returning stream when you bring your tank back to its fill level during routine care. WHAT\'S IN THE BOX — Only the item named in the title. No hardware is included (see the description).

An open intake is one more thing to watch when you siphon a tank containing fish or shrimp. Refilling brings a different challenge: directing incoming water instead of letting it enter as one concentrated stream.

The SplashNColor aquarium water diffuser doubles as a sponge holder for your aquarium water change hook. It holds a sponge in the water-change flow path to guard against drawing fish or shrimp into the siphon. When you switch to filling, it disperses the water coming from the hook into your aquarium, including during fast refills. That gives the holder a job on both sides of tank maintenance, as water leaves and as fresh water returns.

Before connecting it, check that your hose has a 1-inch (25.4 mm) inside diameter. That hose slides onto your aquarium water change hook and the sponge holder to join them in your setup. Match the inside diameter, rather than the outside measurement, when checking your hose.

The screw cap gives you access for cleaning and sponge replacement. Open it to reach the sponge after tank work, then use the same opening when a sponge change is due. The plastic part holds the sponge during use and makes it accessible through the cap for maintenance.

For aquarium keepers caring for a fish or shrimp tank at home, this accessory is for the work behind the view: siphoning water out, filling the tank again, and getting the holder ready for the next change. Use it with your aquarium water change hook to put a sponge at the intake and spread the refill flow where the water enters your tank.

HARDWARE NOT INCLUDED: Only the item named in the title is in the box. Every setup is different: depending on yours, mounting it or attaching it to an existing part may use hardware you already have, such as the original screws, or you may need to buy your own screws, bolts, tape or adhesive to suit your situation. No hardware of any kind is included with this listing.
