Based on my experience, I believe larger water volume is easier to maintain and good filtration seems to be the best solution. I've grown out fishes in a 120 and 225 gallon but needed constant wc to keep water pristine. I now have a 450 gallon with a 135 gal k1 sump and two fx5 running (fx5 will be replaced with your glass filter) in which I do wc once a week. Water stays pretty clean through out the week with the amount of food I feed daily.What tank size do you feel is easier to manage as far as water quality?
I feel that tanks under 300g are harder mainly because cichlas are messy fish and without the volume your filter can't miss a beat. With larger tanks I feel they are more forgiving. Water changes still exist but cichlas are less likely to get sick.
What do you think?
Once my cichlas grow out to 8-9" I know the glass filter will have to be installed. I more than likely will hAve another setup if I keep all these cichlas recently purchased. I'm sick in the head lol
