Thank you for your support of this Tetra kit, Ryott! We appreciate your review! A couple of tips that may help you - I noticed your comment regarding the lights. This light has an off/on button. The button you use to turn it on will also turn it off. No need to unplug it.

In regards to the milky water, this may or may not be a big problem for you. I am assuming you are testing the water since you bought the API kit, so if your ammonia and nitrite are under 2.0 ppm you are fine. Otherwise, do a partial water change. We typically recommend adding Tetra SafeStart Plus when you first add fish to the tank to avoid ammonia spikes, cloudy water, and so forth. It shortens the initial period of the nitrogen cycle, and saves you a lot of headaches if you add this in. I do count at least 7 fish in the tank. If this tank is less than a month old, that is more fish than we would recommend starting it with, and this may be why it is cloudy. If so, keep an eye on your ammonia and nitrite levels.

One last piece of advice - I always find it helpful to keep extra heaters, filters, medications, etc., on hand, even if I don't need them, just in case I have a situation where I do need one, and the stores are closed. I have had it happen more times than I care to remember! There's nothing worse than spotting your prize fish acting ill and knowing that you can't medicate him for 24 hours because you have to wait for a store to open!

If you ever need assistance with your hobby or your Tetra products, please know you can reach out to Tetra directly via PHGAmazon@spectrumbrands.com Happy fish-keeping!

Hi Adam,

Thank you for your support of this product. Actually, the number of fish you are indicating can be kept in this aquarium is not completely accurate. Maximum amount of fish would be approximately 10 fish of the sizes you are describing because the recommended ratio within the hobby and industry is one inch per gallon of water for small tropical fish. All of the current glofish on the market are small tropical type fish that reach between 1.75 and 3.0 inches. The tiger barb variety tends to get closer to 3" in length, so you would keep approximately 7 if you were to stock properly. All of this being said, you are correct in recommending an upgrade in filter size if you wish to overstock as in the 18 animals that you recommended. This can be done successfully if you move up a size or two in filtration, such as to a Whisper 30, and/or are willing to do small, partial water changes frequently, as in once a week.
