Personally I wouldnt trust a heater that boast 200g more then the average 300w heater! Post count dont equal knowledge. 1 300 wat heater for a 180 gal tank, that has to be the worst advice i have heard on this site. I dont like to take risk being a cheapo.
I never questioned your post count or knowledge. I spoke form personal experience of using both products in my own fish tanks. And I qualified it with the fact that the persons circumstances are not the same as mine and the results may be different.
Also being aware of how much the equipment can cost is not being a cheapo, in fact many of us here pursue the hobby with a budget (at least you do if your married!).
So if its not my money I guess I could reccomend just about anything, so if three 300 watt heaters (900 watts) is good than thirty six 25 watts (900 watts) is even better, right? This really would distribute the heat the best now wouldn't it? It really is the ultimate fail safe... Come on I did not attack you personally at all, so dont call me a "cheapo" who gives bad advice or that I pick on people with low post counts as not having knowledge. None of that is true.
