At AquaCave, we offer some of the best selection and best prices on Aquarium Heaters, Fish Tank Heaters, Titanium, Glass, Digital, Heater Controllers for you marine, reef, and freshwater aquarium.
Maintaining the correct temperature for tropical fish may be the single most important factor for a successful aquarium. Since fish do not have the ability to regulate their own body temperature, it is crucial that we can provide consistent water temperatures with minimal fluctuations.
Majority of fish cannot cope with stress from constant temperature fluctuations, which leads to a compromised immune system. This increases the probability of avoidable diseases, parasites, and bacterial infections.
Having a properly sized heater is one of the primary requirements for maintaining healthy aquatic ecosystem.
