i just switched out my stock skimmer to deltec mc500 like a lot of ppl here did. I first realize the noise and heat has been decreased lots. but as for function, the amount deltec pulled out is just tiny bit more than stock skimmer, I cant tell much differences. This can be my tank is already pretty clean, not much waste to pull except the food i fed everyday?
I always wanted to add a sump and refug underneath so i can do tons more modify to the tank such cooling fans, extra water volume, better skimmer and filter socks, all monitor Ato dosing hiding underneath etc
but I step back and think, whats the point of buying rsm250 if you gonna add a sump in the first place? I know its hidden under but it just feels not right to me, Just my 2 cents.
