I only have a pair of clowns and don’t plan on adding anymore any time soon.How many fish do you have in the 10g and how often/how much are you feeding? If doing a w/c is fairly common for you, I think you could get by with 5g w/c weekly if you didn't want to spend extra money on equipemnt. If you were looking for a skimmer, I would highly suggest the Tunze 9001. Great little skimmer for 20g or less.
this 1g is only a holding tank until I can fully plan out my build and save the $$.
i do 5G weekly WC currently, but do have quite the amount of phosphates that rise. My nitrates do come down to about 20ppm but my phosphates don’t budge.
i feed my clowns about 6 pellets each so it’s not heavy feeding. I have had a snail or two due on me so that has to be where I’m seeing a nutrient spike.
