Internal, submersible uv sterilizer filter, pump; review (for aquarium or pond) gas vs electric oven

##############

The Submariner and other similar versions sold on Amazon.com and elsewhere are a slight improvement, however this UV clarifier is still not all that well designed in both water flow rate pattern, as well as lack of proper pre-filtration gas out for water turbidity and the use of low quality medium pressure UV Bulbs resulting ONLY in clarification abilities, not level 1 sterilization.

Although still inferior to out of the water, high dwell time UV Sterilizers (such as the highest dwell time of ANY UV; TMC Vecton or Advantage or even compact UVs with reasonable dwell time, such as the Terminator); the Unique AAP/SunSun Internal UV CUP series with pre-filter, flow adjustment, and low pressure UV Bulb appears to have finally gotten this great idea reasonably correct!

As an example, when a retailer or distributor approaches a typical North American or European manufacturer for a certain product and offers a certain price point that is below what the manufacturer offers the product for, if the manufacturer agrees to the terms, they will get the same product off their production line for this lower price.

• While the grade 9 current electricity test SunSun and related exact same models sold under different brand names have improved in this area over the Submariner, PH-8/UV-3 3 watt and more; these are still below the level of sterilization when compared to either quality compact UVs or especially grade 9 electricity unit test answers the Premium High Dwell Time UVs (such as the before mentioned Vecton Advantage).

My suggestions/recommendation for the 13 Watt or 9 Watt UV Pump/Filter is this is an reasonably well designed device for water clarification or basic level 1 Sterilization for small ponds or small to medium aquariums, especially for those desiring a simple UV application without the availability of a canister filter or similar to power a standard UV Sterilizer.

As it turns out, this so-called deal for these UV Clarifiers is not so much of a deal when you go to replace the lamp/ballast @ $26.99 for the 9W or $39.99 for the 24W, not to mention these are NOT capable of true UV Sterilization which SHOULD BE the reason for purchase gas exchange in the lungs of such a product as often a cloudy or green aquarium is an indicator of poor maintenance such as too-high bio load, over feeding, poor filtration, etc.

As another example, SunSun Basic, JUP-01, JUP-23 13W and the AquaTop PH-8/UV-3, 5, 7, 9 watt Inline UV Sterilizers are not of the more robust filter and UV flow design as the larger SunSun CUP-613 CUP-609, rather these are simply knock offs of the cheesie internal UV flow and over all design of the earlier Internal UV pumps ( sadly still sold by Amazon and many others).

If Clarification is all you need, not true level one sterilization or greater gaslighting for Redox balance, disease control, and fish immunity issues, these above noted filters might be a good choice since these are well under $50 (with the exception of the Deep Blue), but again if you do your research and need true UV Sterilization, you will need to go with a true UV Sterilizer such as the good AAP Terminators or the top notch premium AAP/TMC Vecton/Advantage UV Sterilizers, Aqua Ultraviolet, or Emperor UV.

Very useful information, but I need to ask, I have a fish tank not so big. Just 40gal but I had 2 fishes dying from Mycrobacteriosis and I read at Diana Walstad saying that a 8watt UV gave her amazing results. The Sunsun CUP-613 seems a lil too big for my fish tank, can I still use some model like the JUP-23? both are Sunsun. Please help. 7:46 AM Steve said…

We had an algae bloom in a 55 gallon aquarium that housed several large fancy goldfish. Goldfish are quite sensitive to most chemicals, so I couldn’t use any sort of chemical additive to kill off the algae. Keeping the tank dark and doing several massive power quiz questions water changes MIGHT have gotten rid of the algae, but would have been difficult for me and risky for the fish. I decided to try a UV sterilizer. Professional tests and reviews suggested that the SUNSUN 13W UV Sterilizer and the Green Killing Machine were probably the two best values for what I needed. Both are similar devices that work the same way. Both have a large number of good reviews, and both have a number of reviews pointing out various problems that can occur. And, of course, both products are made in China, where quality control can be somewhat gas and supply shreveport suspect. A little shopping found the best price on either product, from a seller in the US, was the SUNSUN 13W UV Sterilizer from a seller on eBay. When I received my sterilizer, I inspected it thoroughly before using it. As expected, the instructions that came with it were nearly useless, but it wasn’t too hard to disassemble it. I checked each of the likely problem areas and found no problems. As was indicated in several of the reviews, I did remove the plastic piece that the manufacturer uses to hold the UV bulb in shipping (not mentioned anywhere I found in the directions that come with this). I assembled the sterilizer, installed it in the tank, and turned it on. The pump in this k gas cylinder unit moves an amazing amount of water – easily two to four times the flow rate of any common on-tank filter. The water inlet is fairly large, but the outlet is about 1/2 cm2, resulting in a very powerful stream of water. I was a bit concerned that this might be a problem for the fish. The outlet is near the top of the sterilizer which puts it just below the electricity how it works surface of the water. This makes the strength of the water flow even more obvious as you will have waves across the top of the tank! Fortunately the fast water current only effects about the top two inches of the water so most of the tank water is not moving nearly as quickly. The current across the top was enough to push any of the fish clear across the four foot length of the tank, but rather than being a problem, I found that apparently the fish liked it! The fish mostly stayed in the middle and bottom of the tank where there was no strong current, but I noticed that occasionally some of the fish would deliberately swim up to the corner where the sterilizer was installed, then come up to the top and ride the current all the way to the other end of the tank j gastrointest oncol impact factor. After 2-3 days it was obvious that the sterilizer was killing off the algae and by the end of the week the water was crystal clear. Keep in mind that the sterilizer kills the algae but doesn’t actually remove it, so you still need your gas oil mix ratio chart regular filtration to remove the algae as the sterilizer kills it. The reasons I gave this 4 stars instead of 5 are because of the poor instructions and because of the small outlet area which could easily be improved by adding some sort of spreader. This unit is rated for up to a 150 gallon tank but not for a minimum size. Having used it in a 55 gallon tank, I would not consider this unit in anything smaller than a 30 gallon tank and I’d have to think twice about even a 30 – the unit should work OK in a 45 gallon or larger tank with a length of 4 foot or more. To use it in a smaller tank you would absolutely need to find a way to spread out the flow. 8:47 AM Steven said…
