ok im trying to figure out what i will need. ideally 3-1000 true temp titanium but thats a little expensive. it will be in the basement and will be about 20 degree change from air temp to my tank water. im going to heat the 100g sump, and was wondering if there are any standout good cheap ways to do this. for example, i can buy jebo cheapo 300w heaters on ebay by the 6 pack. are these really that much worse than any other heater? its like 80 bucks for 1800w which seems cheapest to me. if i get a dozen will this be good? can i just get a small pool heater? im kinda lost as how to do this without breaking the bank
