Hello.The tank I have has eight cichlids ranging in size from 1" to 2 1/2".I also have one 8" fire eel, one 3" blue lobster, one 6" lemon spotted green pleco, I plan to add maybe 4 or 5 more cichlids.I am currently running on 2 Emperor 400 rated for 80 gal tanks 400 gph each.With succes in the past.But it seems like compared to any one in a forum like this one were people know about filtration I am underfiltered.I hope that makes sense.
My question is would the Rena Filstar XP Canister Filter for aquariums up to 175 gallons with 350gph be a good add on? Or for the money would there be something better.
Thanks I appreciate any comments.
 
thanks

thanks Lorazoo for the comment.The reasond I feel under filtered is I currently have only 2 emperors 400 and everyone in these forums is running like on 3 filters and bigger ones, like sumps and that sort of thing.Dont get me wrong I dont just want to jump on the band wagon but some of these cats sound like they know what they are talking about.
Do you think it would be a good idea to remove the emperors once I get the xp3 or what I was thinking is leaving the 2 emperors along with the xp3.
thanks any comments help.
 
It wouldn't be a bad thing to leave the HOBs on there. Its a good idea to have multiple filtration in case one filter fails for some reason, so you've always got a backup running. Also, even if you think you have enough, it never really hurts to add more, especially on a big tank, it will help promote water circulation and hopefuly lead to less dead spots.
 
I'd add the XP and leave the 400s' on the tank. Considering the fish you have and your plans to add more, you will benefit from it.

I've never trusted the size/GPH the filter manufacturers quote. It is often in ideal conditions with no media/baskets in place. The items added inhibit the "rated" flow drastically. I hope for half of what the stated gph is and filter for 4-10 times the tank volume depending on the inhabitants.
 
With or without the XP series, I would never suggest removing both of your emp 400's. The biologicial filtration in those filters is second to none, not to mention that you could potentially see a major spike in toxins like ammonia after removing the housing of much of your beneficial bacteria.... I have sympathy for your situation because I struggled with the same decision several months ago when I upgraded from a 55 to a 135gal. Eventually, I bit the bullet (financially) and went with (1) HOB emp 400 and (2) Rena XP2, which I am running on opposite sides through undergravel. I couldn't be happier with the results thusfar.
 
same difference?

Sounds like the same situation.What do you use on the Xp's the spray bar or the jet addapter.My big delema is since I just got the XP3 I put on the spray bar and it filled the tank with little air bubbles wich im not too fond of.
thanks
 
I opted for the jet nozzles, which I have on opposite sides of the tank pushing water towards the emp 400. I like the spray bars look, and may switch to them someday and install a power sweep or 2. Anywho, there are 2 benefits that I know of to the jet nozzles. (1) increased water movement adds and distributes oxygen more evenly throughout the tank. This becomes more important with the larger tanks (2) increased water movement helps to cool water temp. My heaters are set at 78, room temp is around 82, yet the water in my tank is at 80. But it's not so effective that it will over-ride your heaters in the winter time.

you must have air in the lines (you didnt prime the pump properly)


try disconnecting everything and proming it properly to remove the air bubbles.

remember, the more air in your pump, they sooner it will die on you.
