Question XP2 and Fish

Is it possible that the XP2 flow is too high in my 55 gallon when the valve is set to the full open position?

I have had Cardinal tetras for a month now and they always hide in the bottom corner, I thought it was because there were only 6 of them. (I am waiting for more to come into the LFS)

I got some swords tails and mollys last night and they aren't swimming around, they tend to hide in the plants. Should I just be patient since they are new to the tank?

Thanks!

Have you tried reducing the flow?

Talking Xp2

I wasn't sure if that would slow the circulation too much, or damage the motor.

On my Eheim I only use the outflow to to make adjustments. Am not familiar with Xp's. Some one who is will probably chime in soon.

My Cardinals tend to stay low in a corner if the current is too fast.

Either throttle down the flow (via the outflow. You can dial down the quick disconnects), or you can try to turn off the filter for a bit and see if they come out of high

No, it's not possible. Cardinals are strong swimmers, and that filter will not ever overpower your tank. They are skiddish fish, and mine always hang out in the plants during the day when they can see me. New fish often hide in plants too.

Same here. My cardinals only come out later in the day when the lighting in the room keeps them from being able to see out of the tank.

I have the XP2 in a 55gallon tank too and everything seems fine. I dont reduce the flow. Are you using the jet end piece or the "flute" pipe. The flute pipe might give you weaker current over larger area.

The only change I have made is to add a sponge pre-filter.

I highly doubt you have too much flow, what are the water parameters?

Cool

I haven't tested the water parameters yet today, I will when I get home. It was fine last time I checked it though.

I have the xp3 using the spray bar (flute tube) and have it mounted horizontal spraying left to right. I have the flow at about 3/4 power and it seems to do good in my tank. My top swimmers (danios) will swim into the current and at feeding time the tetras and danios will swim into it to get to the food.

I would say to experiment with the flow and see how the fish behavior changes. I have black neons tetras in my 10g tank that are simply skittish and stay behind the plants anytime I am in the room.

Good luck with it.

Thank you!

I was wondering why no one had chimed up.

As a matter of fact... I consider an xp2 too LITTLE filtration for a 55g tank.

My cardinals in a 29g tank don't mind a koralia nano, ac30, and punguin hob.

I have 2 55's both with XP2's. No way the flow is too strong. I actually have added a Koralia 2 to each of the tanks because the flow was not enough. I have cardinals in one of the tanks and have no issues with them even with the added flow of the Koralia.

Cool

I wanted to have the spray bar in the tank to point from the right to the intake on the left, but the bar was too long for that.

Seriously a 300gph flow rate is too little? That is a turnover of 5+ times an hour. Here is what I have in the filter (pretend you are looking at it from the side)
