Filtration questions.

[Leighlou]

I don't mean to highjack the thread but I want to set up a 75 gal tank with several fancy goldfish in it. Would something like this be enough for them?

Sorry its the 500/110 model, though if I remember right the filter should be able to filter the whole tank 4 times in a hour so the 300/70 should work yes?

the ps3 is the old version and the ps4 is the newest version. difference is the ps4 has a improved over flow box and a 1,000GPH return pump and a improved skimmer if your using it for a saltwater tank fresh water you dont need to connect the skimmer part, the ps3 uses a 700GPH return pump. and the ps4 system is on sale at big als for $179 and the old ps3 one is 279.00 weird pricing. they look identical the ps3 and ps4 its just a few improvements is the only difference. the first one i ever bought was off craigslist a ps3 i got it for 50.00 and liked it so well when the new ones came out and and were on sale i started selling off my old filters and buying the ps4's.

great thanks!
