Reverse Osmosis and Deionization is a process whereby water is purified as the water gets pushed through some sort of membrane. The membrane traps the impurities and they can remove 90% - 99% of the impurities from the water. The type of membrane you use determines the amount of impurities that the Reverse Osmosis unit will remove. Our drinking water often includes minerals, heavy metals (mercury, copper), phosphates, nitrates, pesticides and herbicides (from farming and lawn fertilizers), chlorine and chloramine. These can all be potentially harmful to your fish. However, most municipalities do a decent job of eliminating most of these impurities from our drinking water. Water treatment plants add chlorine and chloramine to the water to kill any harmful bacteria or other "bad stuff". One side effect from using a Reverse Osmosis unit is that they will remove some of the "good stuff" along with the "bad stuff". Because of this you will need to add the "good stuff" (minerals and other essential elements) back into the water before using it in your aquarium.

There are products on the market called RO Conditioners which are made specifically for this process. R/O Right is one product that contains the essential minerals and other elements that your fish need. It should be noted that these are only used for freshwater tanks because saltwater mixes already contain the essential elements you need. Is a Reverse Osmosis Water Filter Really Necessary? If you are planning on keeping a saltwater reef tank with various corals and anemones or a particularly challenging freshwater species such as Discus, it may be a good investment. If you live in an area where you can only get well water or your water source is suspect, it may also be a good investment. It really depends on the water coming out of your tap. Some water treatment centers will send out annual reports of the water quality in your area. If they don't, there are places that you can send your water off to be tested, all for a fee of course. For most freshwater hobbyists these Reverse Osmosis units probably are not all that necessary.

Many tropical fish hobbyists have been keeping fish successfully for years without using a Reverse Osmosis unit. If you're a reef tank keeper though you will probably need to invest in one. RO units are usually fairly expensive and you probably don't need one if you have decent water quality. Research your tap water to determine the amount of impurities your water contains and then make an educated decision on whether or not you really need to purchase one of these units. Reverse Osmosis Water Filter Maintenance You will need to perform maintenance on your RO unit periodically. How often hinges on how hard your water is and/or how many impurities are included. You can get an RO flush kit that removes some of the lodged deposits in the membrane and potentially prolong the useful life of the membrane. These flush units are usually inexpensive and can some you some money by prolonging the life of the membrane. Deionization is another type of water purification. The deionization unit works by utilizing a process known as "ion exchange".

Without getting too technical, this basically means that it removes the impurities and replaces them with pure water. where to buy a small fish tankDo you really need to know exactly how it works? fish tank for sale in florida Deionization units are usually used in conjunction with RO units to give you 99.9% pure water. fish tanks for sale in virginia beachThe tap water is usually first pushed through the RO unit and then sent to the Deionization unit for further purification. You will need to test the output water from these units periodically to determine if they are still producing pure water. Get water test kits that will test the General Hardness and the Alkalinity of the water.

You want both readings to be 0. If the test readings start to trend higher you will know that you soon need to replace the membrane and/or cartridge. The easiest and quickest way to tell when your Reverse Osmosis filter needs to be changed is to use a Total Dissolved Solids (TDS) meter. I like to change my cartridges out when the TDS measures over 10 ppm or so for my reef tank water. Still need more information? Check out the video below from BRS which explains a 5 stage RO/DI filter. It is worth watching. Author : Mike FishLore How To Setup A Quarantine Tank © - providing tropical fish tank and aquarium information for freshwater fish and saltwater fish keepers. Aquarium Fish SiteMap | Aquarium Fish Dictionary | Clear Flow Aquaponic Systems® are complete system packages and include all of the components in the aquaponics loop: all tanks, filter tanks, tank stands, grow beds, plumbing, pumps, valves and the aeration system. There are additional items that some people need and others do not, depending on their climate, crop choices, infrastructure, etc.

Those items are listed here, along with suggestions on growing supplies that you will use over time. Each hobby system comes with a starter pack of rockwool grow cubes. Commercial systems do not include grow cubes. You can purchase cubes by the sheet or the box. 1” cubes = 200 cubes/sheet 1.5” cubes = 98 cubes/sheet Our Home Food Production systems use the 1.5” cubes. Our Commercial systems use the 1” cubes. How many boxes do you need? Look at the annual production of leafy crops and determine what size supply you need for a given period of time, for instance, 6 months. Nelson and Pade offers a premium fish food designed for use in aquaponics.  It provides the nutritional needs for an omnivorous fish, like tilapia or blue gill.  All ingredients are sourced as non-GMO. The proteins come from fish meal, fish oil and ground peas.  We offer both starter diets and grow out feed.  There are several key water quality parameters that you’ll want to monitor regularly in your aquaponic system.

During start up, you’ll monitor frequently and over time, as your system becomes established, you can monitor weekly, or as needed. At a minimum, you should have test kits on hand for: ammonia, nitrite, nitrate and pH. Dissolved Oxygen (DO) is another critical factor and is best tested with a DO meter. We offer two options, a DO meter kit and a DO Pen. We recommend starting all plants from seed in an aquaponic system and it is most efficient to start the seeds in a smaller germination system than in your main culture system. A seed germination system is included with all of our commerical systems. For Home Food Production Systems, we offer seed germination kits, which include the grow tray, a clear dome lid, a heat mat and a thermostat. Each kit holds one sheet of 1.5” Rockwool cubes (98 cubes). You manually water the cubes in these trays with water from your aquaponic system.  Maintaining proper water temperature will keep your fish healthy and enhance plant growth. Plus, when the plant root temperature is in the right range, you can let your air temperature drop to lower than normal levels.

In a greenhouse, this saves you energy because heating the water is more energy efficient than heating the air because of the heat loss factor in the greenhouse. Our inline water heaters are electric, 220v and are available in sizes ranging from 2kw – 8kw. They are designed for continuous flow. The size of the inline heater you will need depends on your climate, crop choice, other environmental control and the size of your system. The inline heater installation kits (sold separately from the inline heater) includes the plumbing and valves you need to make a heater loop, so that you can install it inline, but still have the capability to by-pass it for maintenance. For heating the water in larger commercial systems, we offer a hydronic heating package that includes the hydronic tubing, plumbing and manifolds. In this system, hot water flows through hydronic heat tubes. The heat is transferred to the system water. It is very efficient and the hot water can come from a boiler using wood, natural gas or propane as a fuel source.

We can put windows in the fish tanks of any of our systems. Windows allow you to see the fish swimming, monitor their behavior and feeding habits. People love to watch fish so having windows in your fish tanks will make it more enjoyable. Our window kit includes the window, hardware, silicone and instructions. We cut and drill the holes in the fish tanks so when you receive it, you follow the instructions and glue the window in place. We don’t ship tanks with the windows glued because jostling in shipment cause the seal to break. Note: windows in your fish tank will require regular maintenance to keep them clear and free of algae or debris. Our commercial systems each have either four or six fish tanks (depending on the model), which are stocked using a staggered method (one tank every 4 or 6 weeks when using tilapia). We recommend stocking the tanks with 50 gram fingerlings. If you can purchase 50 gram fingerlings, you don’t need a nursery. If the fish you will buy are smaller than stocking size, you should start them in our nursery system.

This is a very efficient method of starting with fry (very young fish) and growing them to stocking size. Our fish nurseries are complete aquaponic systems that include plant grow beds so you get get some early plant prodcution even before your commerical system is operating. Our fish nursery systems come with an inline heater to maintain proper water temperature for your young fish. If you are just building your greenhouse and aquaponic system, you can get a jump start on the start-up time by setting up and stocking your fish nursery first.  When planning where you will put the nursery, remember that the plants in the grow beds will need sunlight or grow lights. If you are raising fish to eat, we highly recommend a purge system. Using our purge system and purging techniques, your harvested fish will have a clean, fresh taste. The meat will have a firm texture. With any farmed fish, if you don’t purge them, you will likely be disappointed in the quality. If you are raising ornamental fish, like koi or goldfish, you don’t need a purge system.

Our purge systems are available in multiple sizes so you can pick one that best meets your harvesting and marketing plan. The purge systems are stand-alone aquaculture systems with a single fish tank and filtration components to keep the water clean and fresh, resulting in the best tasting fish. Our monitoring systems provide you great comfort in knowing that everything is ok in your aquaponic greenhouse, whether you are there or not. We supply the sensors and system to monitor all of the critical factors in an aquaponic system and if anyone of outside of the set point or not working, the monitoring system will contact you. Available in web or phone based versions, for 24 hour monitoring. When using the ZDEP® system, you can expand and diversify your production with media beds in your greenhouse. This allows you to utilize all fish waste from the ZDEP® filter to grow more plants and a more diverse crop selection. In the media beds, you can grow beans, peas, broccoli, beets, radishes, carrots, cucumbers, peppers, tomatoes and other crops.
