Question: Would it still be able to operate if one of the filtration cartridges is removed?
Document: I did waver between 4 and 5 stars because the quick connectors will leak if you don't resecure them before each use. But that is such a minor inconvenience that it is barely worth noting.My reef aquarium is doing much better even after only one water change with this device. I very highly recommend it!
Overall, a great product, I use it weekly. I went to 4 stars, because the attachment for the tap it came with was garbage. I had to run to the local hardware store and buy a metal one, that cost a little over $2, but outside of that, this does exactly what I need for water in 2 30 gallon reef tanks.
First off, finding a 4 stage RO/DI unit for this price is astounding. I actually stumbled across it through an aquarium forum, and had it not been recommended by an experienced reefkeeper there, I would have dismissed it as too good to be true.I am glad that I didn't! It is simple to assemble, lightweight enough to transport, and comes by default with a hookup for any faucet with an aerator (most bathroom sinks and many kitchen sinks).
I can't lie. I freaked out when it came first: tubes and compartments with just picture instructions. I almost sent it back!But the company sent me better instructions via email and apart from a never-ending leak situation around the tubes (which changes once you re-position the tubes a certain way + thread tape), it works!My tap water got 144-146ppm, which went to 000ppm with the filter.Would recommend to others.
works great right out of the box no leaks! It got delivered to our house before the scheduled time of deliveryI put it together and immediately started making water for my new 135 gallon reef tank the water test at 0 ppm (everything) good deal:-)
amazed because of the low price I was skeptical. typically you get what you pay forI only need about 1 Gallon a day (fish tank)
Bought for an upcoming reef tank. Had to buy an adaptor from the Home Depot to attach the input to a garden hose but otherwise setup was easy and no leaks. 0 ppm TDS right from the start. Will have to see how it works out in the long run but at the price, you can't beat this RO/DI.
After receivingthis system, I was making water within 20 minutes! Awesome product and price! It has already paid for itself at least twice by now, considering  that the RO water I was getting cost approx. 90 cents a gallon. A must for any salt water enthusiast.
A 5 star General Rating all the way for this product! This filter kit is  exactly what a guy like me (salt water aquarium hobbyist)was looking for. Performance is excellent at 0 TSD levels. Price is lowest I've seen anywhere. And if that wasn't enough, it comes with several attachments and adapters so that there is a good chance it will fit whatever type of faucet you may have. It was leakproof from start till now, and I've had this for about a month.
