I am doing 20 Longs split 4 ways for my growing bettas. I need 4 heaters and not wanting to buy super expensive ones. If i split the tanks my usual jagers wont fit since they are so big. Is aquatops and the deep blues a good heater for the price. Also is 100w adequate enough to keep 20 longs at 80 with ease. Well not stuggling with it on all the time.
