It might as well be another 300 for minimal cost difference in comparison to a reef setup total!Got it. I'll run down and grab another one today.
Do I need another 300? Should I grab another fluval or is they're an equally priced fully submersible I should be looking at?
You could check out Finnex titanium heaters, BRS titanium heaters, Eheim, and Jager in addition to Fluval. I have heard good things about these heaters. Also, having equipment redundancy (2 instead of only 1 in this case) is always a good idea when you can afford it.
I personally have two
(I just looked at my heater order and discovered that I decided to pay the $15 more for each heater and get 800W instead of 500W, not even the 300W previously mentioned. Again, bigger is better when maintaining temperature on a large volume of water.)
