V2 Sand Car Plans 25gallon Marine Fish Only With Live Rock...?

25gallon marine fish only with live rock...? - v2 sand car plans

hey guys, in the process of cycling my 25g customized version 90lx40wx31d (cm) NANO FOWLR;
120 nano v2 skimmer
Tetra TEC 150L internal pump
Heating 150w Premium visitherm
Fiji LR 5 kg
Substrate of sand live
large amount of dead coral rock and a man with a large number of cache --

I'm new at this and have studied hard (especially on set-up, but now, the fish, etc.), but wondered if anyone could answer a particular question.

I know my tank is low and the filtration is not only more power and whether certain types of experience in salt water, you let me know if this is too high bio-load, while a change in water 25% per week:

I thought of two possible configurations
a)
1 Six-Line Fish
1 clo false perculaWN
1 Coral Beauty (Givi were conflicting views about whether a 25g is sufficient, please contact)
1 Banggai Cardinal
1 Duster
1 cleaner shrimp
10 Turbo snails Astrea

b)
1 Valentini President (swollen than the beauty of the coral)
1 incorrect percula clown
1 Six-Line Fish
Coral Beauty 1

any advice would be great.
