90 gallon question

1499 Views 4 Replies 3 Participants Last post by  pro zac
ok so i was planning on buying a second penguinn bio wheel 350 for my 90 gallon tank because there was a good sale at petsmart. well i didnt realize that the sale ended on the 18th so now it is regular price again. (47.99 i think)
my question is do i really need another filter for my tank? i have 14 cichlids in the tank right now and 2 small plecos and will be stocking 20 to 30 eventually.

thanks for the help!

If you want the bio wheel 350, go here and print this off. They should price match, mine does.
Did not go thru like I thought it would. Click on the model arrow and go down to the 350. It's only $26.99 online.
awesome! thanks i didnt notice this price online being different!
im gonna get another one wheter i need it or not for that price!
If I'm reading this right, you have *a* penguin 350 on your 90 gallon, and you're asking if you should add another?? Is that right?

If so...I'd definitely add another one, maybe another two. That's just me. I believe the commonly quoted rule of thumb for HOB filters is 10x turnover/hour. 700 gallons/hour falls a little short. You can always add another one down the road; you don't have to add it today.
yes you are correct i have 1 on the tank and am adding another one today. i went to petsmart but they were sold out so i called around to another close petsmart and they are holding me the last one, til after work.
i thought my penguinn 350 was rated for a 125 gallon tank but i was noticing on this forum the speak of multiple filters and higher number of fish and decided i needed another filter!

i dont want to add three of tehm though, with the two penguinn 350s on will i be able to take out my air stones since the top of the water will be constantly moving?
