Hey so actually i just figured out i have a 20 gallon tank..... how strong of a light bulb will i need.... I bought a zoo med repti basking bulb 100W but i found it to be to strong..... I am going to be using two bulbs one for heating, one for UVB(The esu Coil bulb 20W for 19.99 at petsmart)... I am thinking of exchanging the the basking bulb to a 50W will this provide sufficient heat for my turtle....
And ALso i heard you can get UVA from a standard light bulb.... is this correct..... what is UVA exactly?? JUst Heat??
