Needing high quality tropical fish products and food? Look no further

What type of tropical aquarium is your particular preference? Novices should really kick off with something quite big. The environment is far easier to maintain control of if you invest in something like a 20-gallon tank. We can provide you with one of those, with ease. And if you're an experienced fish lover, we've got lots of aquarium options for you too.


Adjust the water temperature, almost effortlessly 


Feeding your fish a couple of times a day, with small amounts of food, is pretty easy to do. And you can keep your aquarium light on for up to 12 hours daily (although it's probably best to keep that to 10 hours max, to be on the safe side – fish just prefer it that way!). But how often should you check your tank's water temperature? Well, 78ºF is optimal. Any higher than that, and you might have problems.


Amongst the wide range of products available to buy from Watermarque are good quality thermometers and hydrometers, which will allow you to control your tank's water temperature, quickly and with very little effort. You love your fish. Don't take chances. Invest in a good water temperature tester and then enjoy peace of mind.
