Thanks to all for sharing, enjoy seeing everyone's interpretation of our hobby. Will post some when my youngest son teaches me how. He's 29 but is my IT support. LOL
one the one tank i run a Rena Filstar XP3 canister and a Topfin 60 HOB. i've got both filter intakes right down to just above the gravel and the spray bar for the XP3 has the holes pointed straight up. works great.
one the other (planted) i run an Aquaclear 110 and an Elite Hush HOB rated for 50 to 60 gallons.
basically, i run one filter for the biological filtration (sponges and biomax) and the other filter on each tank is for water polishing (filter floss only for the most part).
overfiltration on my tanks? you betcha! lol. i always run two filters on each tank.
