dont get me wrong, it works wonders, but for such a small tank and it being fowlr
for now a skimmer isnt needed with a good hob
filter and light feedings and a good cuc, he'll have a healthy system, if he wanted to make it a reef and add corals and higher experience level fish he could always add a hob
skimmer later on if thats the case, but for his setup now a good hob
paired with the powerheads is a great setup for a 20g tall.
with a topfin 20 hob
and 2 koralia 240 ph's he'll have a 29x water turn which is ok for a fowlr
with a topfin 30 hob
and 2 koralia 240 ph's he'll have a 31.5x water turn, which is great.
with a topfin 40 hob
and 2 koralia 240 ph's he'll have a 34x water turn which is even better.
