EHEIM Automatic Feeding Unit

The EHEIM Automatic Feeding Unit (Buy Online) has all of the features you would want in an automatic fish feeder. This is one of our favorite feeders because it is so simple to use. You can program this feeder to dispense flake food once a day or all the way up to four times a day if you like.
Programming this feeder is a simple task thanks to the large easy to read LCD screen. You also have the option of programming this feeder to release a single serving or a double serving with a 1-minute delay. And there is a manual override button that will allow you to feed your fish any time you want.
The feeding drum that holds the flake food on this automatic fish feeder will hold up to six weeks of food. The exact capacity of the feeding drum is 3.3 fl oz (100 ml). And it is made of transparent plastic which makes it easy to see how much food is left in the drum with just a quick glance.
This feeder dispenses food by rotating the feeding drum, which allows the food to fall out of a hole on the drum. When the feeding drum rotates it also helps agitate the fish food in order to prevent it from sticking together and forming clumps. The rotating drum along with the very good internal air circulation makes this feeder much less prone to jamming up than other feeders on the market.

The twice-daily option will feed your fish once at the start of the 24 hour period and then 8 hours later. And if you select three feedings a day it will dispense the first serving at the beginning of the 24 hour period, and then the other two servings will be released every 6 hours after that.
The timer in this feeder is set as soon as you insert the batteries into this device. That means the first feeding cycle will occur every day at the same time you first inserted the batteries. For this reason, it is important to install the batteries into this device at the exact time you prefer to feed your fish. This unit uses two AA batteries that are not included, so be sure to take that into account when setting up this device.

This feeder is pre-programmed right out of the box to feed your fish twice a day at 8 am and 6 pm. Or if you prefer to set your own schedule you can program this feeder to feed your fish up to 12 times a day.
What really sets this feeder apart is the moisture-proof design. The way this system works is by retracting the feeder drum into the body of the unit in order to completely lock out moisture. This is achieved with a rubber O-Ring gasket that tightly seals the feeder drum when it is not in use.
The airtight design and rotating feeder drum will ensure that the flake food inside will never clump together and clog up the machine. And keeping moisture out of the feeder drum will reduce the risk of dangerous mold and bacteria from growing on any of the fish food.
You will also have two options when it comes time to power this device. This feeder can run on 4 AA batteries or off a 6-volt adapter. Having the option to use a 6 volt AC adapter is great if you plan on going away for a long time.

The feeding drum of this device holds 2.7 fl oz (80 ml) which is large enough to hold four to five weeks of food. The drum automatically rotates and agitates the food when it dispenses it in order to prevent the food from sticking together and jamming the unit. And this automatic feeder has an airline connector, so you can keep the food drum well ventilated by simply hooking it up to an air pump.

When a feeding cycle occurs the feeder drum rotates around and a transparent door opens which lets a portion of the food fall out. Then when it rotates back around, the door automatically closes back up in order to keep moisture and any other debris out of the drum.
You can also manually feed your fish whenever you like by simply pressing the instant feed button. Which is great if you want to give your fish a little treat whenever you are around to perk them up.

Oscar Fish Water Parameters Oscar Fish Water pH Level Oscars prefer water with a pH between 6 and 8, but they prefer slightly acidic water and they can live in water that has a pH as low as 5.5 quite comfortably. Oscar Fish Nitrite Level The nitrite level in your tank should be at 0 ppm once your tank has cycled. Nevertheless, a weekly 10% water change with fresh water from the tap is always good early on in the cycle to reduce nitrites. Oscar Fish Nitrate Level To keep your Oscar healthy you want to keep your nitrate levels between 10-40 ppm. It's important that you test the water with a Nitrate Test Kit (Buy Online) to ensure the nitrate levels in your tank aren't reaching dangerous levels. If the nitrates in your tank stay consistently over 40ppm, it’s time to clean or replace old filters, clean out uneaten food, vacuum the gravel, and do at least a 25% water change. Oscar Fish Water Temperature The ideal water temperature for Oscars is 75-80 degrees Fahrenheit (23 - 27 Celcius). It's important to remember that Oscar Fish are from the Amazon Rainforest and they need a heater in their tank especially during the winter time If you want to know what size heater you need for your tank you can use our Fish Tank Heater Calculator (Click Here) Oscar Fish Water Change Water changes are an essential part of fish keeping for any type of fish. This is especially true when you have larger fish like oscars that produce more waste. Water changes, or partial water changes, should be done every 1-2 weeks depending on how many fish you keep in your tank Why Is My Oscar Fish Tank Cloudy Fish tank water can become cloudy for a few reasons. The most usual is that the aquarium is either experiencing a bacteria bloom or there is algae in the water column. If this is the case, you’ll need to do a 50%-75% water change immediately. You can also use an inline UV filter if water changes and regular tank maintenance aren't getting control of your cloudy water problem. How To Keep an Oscar Fish Tank Clean Water Changes Vacuum the Gravel Bed Cleaning the Filter Removing uneaten food from tank Check for any algae growth on plants or glass walls of aquarium and clean as needed Test the water regularly Do Oscar Fish Need a Filter Yes, Oscar fish need a filter because they are messy eaters that produce a lot of waste. The filter helps with this issue and also improves the water quality by converting harmful ammonia into less toxic nitrates.](https://thepetsupplyguy.com/wp-content/uploads/Best-Filter-for-Oscar-Fish-Tank-464x290.jpg)
