Ok , hi friends , so there is so much information on flow. Can anyone just answer if this sounds ok ? I have a 20 gallon tall nano reef. So, they say 10 times the gallons so a 20 would only be 200 ? My tidal 55 HOB puts out 250 on full but I don’t have it on full. I also have 2 eflex powerheads. Each 660 set at 20 % each so that is 134gph each plus half the filter flow. So I’m guessing I’m running like 268 plus like 125 so a total of 393. Say 400. Is that good enough and not too much. Thanks for any straight answers
