I have two of these tanks, a 2.5-gallon purple and a 5-gallon teal. The 2.5-gallon I use as a quarantine tank for my saltwater four stripe damselfish. The five-gallon holds 1 male VT betta fish, 1 Cory's catfish, 2 Florida neon tetra's, 1 snail, and 1 cleaner clam. I do not recommend using these tanks for saltwater fish. The filter and lights aren't strong enough. I've been in this hobby a long time so I am able to control the water quality with my 2.5 gallon and since it's a qt tank the fish are not in that tank more than 3 weeks and only 1 fish at a time...  also I do not recommend putting as many fish as I have in the 5 gallon tank like I said before the filter and lights aren't strong enough to carry that large of a bio-load, unless you know what your doing and know how to control water quality I would recommend 2-3 fish max depending on their size. Nothing that would grow more than 3" and remember to buy a heater for tropical fish

Good fish examples for the 5-gallon:

- Betta fish  (Siamese fighting fish)

- Guppy

- Catfish

- Tetra

- Danio

- Minnows

- Mollies

- Platies

For the 2.5 gallons

-Betta Fish

-1 or 2 SMALL catfish

-4 SMALL tetras

-Minnow

-Danio

-1 Mollie

-1 Platie

FISH I WOULDN'T RECOMMEND FOR EITHER TANK

-Fresh water sharks

-Cichlids

-Sucker mouth catfish

-Large catfish - (redtail cat's can grow bigger than a dog (4 foot 7 inches to be exact)please do NOT ever buy one unless you have a 500 gallon tank or larger with a massive filter!)

-Sword tails

-Plecos

-Rainbow fish

-Loaches

-Killifish

-Hatchets

-Gouramis

-Discus

-Angel

The product is well made and will last a long time. But for a 10 fall in tank it's a bit big. You have to use an up and down motion to start siphoning the water and you don't have the room to do it. I would get one that has a value.

I don't know what 40 gallon tanks these would fit, but it DID NOT FIT EITHER of of my 40 gallon breeder tanks!!!!! It is WAY TOO SMALL!!!!

I was using this on a 45 gal corner tank.  It worked for the temporary time I had the tank set up.  I'm sure it was fine for the fish but it didn't brighten the aquarium enough to fully bring out all the colors.  I would stick to a something no taller than a 20 gal long tank, although you'd want the wider light for that.  A 20 gal tall would be pushing it.

Note that I am a fish enthusiast so I'm a lot more picky than the average person.  For a first tank with PetCo fish I think you'd be totally fine with it.  And it's a better price than you'd find in one of those stores.

Very disappointed , i have had 55 gallon fish tank's for 35 years for breeding and my own personal fish tanks and this air stone produced very few bubbles, saw the reviews and thought this would be great to try but just did nit produce the results it promised so returned ti right away, i have three 55 gallon tanks and just ordered one to try before i ordered the other two and am only speaking from my own personal experience !!

Works great for smaller tanks. I did notice the tank lid is always wet so keep that in mind for your tank. Only 3 stars cause its preety bulky in a small tank. Not sure if it states it somewhere but wouldnt recommend  in a tank that is less than a 10 gallon breeder. 10 gallon fish tank takes up a lot of room. If that makes sense

I bought this air pump that is labeled for use with up to 30 gallon tanks.  I have a 10 gallon and this pump does not have enough air pressure to run a 5" bubble stone!  It is quiet--maybe because it is doing so little!!!

UV sterilizers are a good thing, especially in the reef tank where most medications will kill expensive corals.

I purchased two 9 watt units (for a freshwater and a reef setup).  Below are the problems encountered:

(1) assembly-  it would appear that it would be a very simple procedure to attach the hoses from the canister filter to the input / out put of the coralife unit.  This in fact was the main reason I purchased this over other models.  The problem, this seal is NOT at all water tight.  Expect water every- where.  The units I was attaching were fluval canister filters (which are the predominate unit in the market place).  I was able to remedy this with several units of plumbing tape, but be prepared.

(2) One unit broke in less than three months, I discovered the other unit was not working several months later when my reef tank fish came down with ich after I introduced a new fish.  I tried new bulbs but it was the ballast from the units that was defective.  I spoke about this to a friend who informed me his two units lated less than a year.

(3) instructions are vague on hook-up specifications, only stating the estimated tank capacity these units can accommadate .  Instead before you purchase ANY UV unit make sure you know it's flow rate and the flow rate of your filter.  Even though they say a coralife 9 watt unit can accommadate a tank up to (I believe 100 gallons), the flow rate required is that of a fluval 105, which no one would use as the primary filter for a tank this large.

In conclusion a good design with the "twists" increasing dwell time with poor exacution.  If you purchase a unit check it frequently to see if it still works, also do not expect it to continue working past the 6 month time frame!!!!!!

Have a 40 gallon fish tank.  great price need to change filters often

It works, that's about all I can say. Bought for a 10 gallon and it's probably more suited for a 3 gallon and under tank. The flow is really, really, low maybe 60GPH when nothing is attached to water pump but after the elbow it's more like 40gph then after the filter it's like 20gph. Pathetic. Using on a shrimp tank so they don't mind how weak it is but it means less crustaceans I can sustain in this tank. Waste of money.

Works just fine. It's really powerful for a 30gal tank, but it's smaller then I thought it would be and its a nice design.

THIS IS FOR 40 Gallon tanks or larger!

I was buying my first gravel cleaner and bought this.  If you look at the packaging, it says it is for 40 gallons or larger, but I couldn't find that listed anywhere in the actual information.

I'm the kind of girl who says, "I can make it work" and then tried to use it.  It made real quick work out of my tank once I actually got it to work.

I didn't buy this. But I'm telling you guys that you can make a refugium better and cheaper at home. Wait til petco has a dollar per gallon sale and buy yourself a 30$ 30gal aquarium. I made mine under 80$ and its awesome.

Im using this for water changes in my 60 gallon aquarium.  I place the pump in a bucket, gravel vac from tank to said bucket.  The pump sucks water from the bucket through 25 feet of tubing to a bathtub two rooms over.  I have to pinch the gravel vac tube sometimes to let the pump catch up.  To fill the tank, I fill a 30 gallon container in the bathtub, insert to pump and move the water back through the 25 feet of tubing, up 5 feet and into the tank.  It isn't the fastest pump and I wish I had bought a larger one for my use -BUT- it does work and I have no complaints about the pump itself.

Way bigger than I thought it was it didn't fit well on my tank, if you do buy make sure you have a really big tank

Doesnt get my 1 gallon tank warmer than 76. Not the best for a betta fish.
