Fish Only With Live Rock And Zoas. I run a 90g reef system and the fiance has taken a liking to all the fish not allowed into the zen atsmophere of the reef system and the aggressive feeding rituals.rofl. hence the need for another tank. thinking a 90g system next to the reef. I am looking for input from fowlr tank owners on the benefits youve seen from running the extras such as a sump skimmer reactor etc. and or if the simplicity is suitable. Im looking to go basic and figuring the 90g with 2 oversized for the water volume hob simple filters with 1 running media and the other with cheato and a simple light for both DT and make shift fuge. I do a 10g wc on the reef weekly and figured I would do a wc on the fowlr tank every other week using the reef tank water and adding from 5-10g new SW making the ratio 15-20g wc every other week.?.
