Question What pre-filter for Rena XP4 XL?

Hi guys,

I am in the process of setting up a new 75 gallon tank that will have some fry & shrimp in, and I am trying to figure out what pre-filter I need for my Rena XP4 XL filter to avoid losing any that way. I see there are the nice foam ones, and I see some nice looking stainless mesh ones. Is one better than the other?

Thanks,
Matt

Welcome to the forum. That is some crazy filtration on a 75 gal. I have the XP3 on my 55 gal and that's because I have goldfish. I have just basic sponge pre-filters and they work fine. Sponge pre-filters seem to work fine on my tanks with shrimp. Some of my filters come with them pre-formed, but for the others I have just cut into an Aquaclear sponge. Haven't lost a shrimp to them, yet.

I have the same filter for my 75.
The metal ones really look nice but the truth is shrimp like being able to pic at a sponge right there. Metal take the fun out of it for them.

Thanks for the replies, everyone.

Bear with me, but I assume from what I see, that the AquaClears are just bascially slip-on sponges that go over the existing filter pickup? I am having a little trouble finding one that would fit the XP4, which I think has 5/8" hose. They also appear to be the coarse foam, is that better than the finer foam & won't impede flow? I see the ATI Hydromax & Filter Max sponges look more readily available. How are those?

Also, Agent13.......
While I am thinking of it & since you have a similar tank, should I get a a circulation pump to help push back across the front of the tank? Would that be a problem with fry getting sucked in as well?

I've been able to sort out most of what I need from researching & reading, but these ones seem to be tougher to find answers for.

The AC sponge is in the middle between fine and coarse. The AC20 sponge may not be large enough, but the rest are for sure. And they are readily available.

wait a minute.... I think I may have been thinking wrong here... are we talking a block sponge from an AquaClear, or is it actually a nice looking cylindrical sponge piece?

They look like a block and come in many sizes. But I'm getting confused too lol. I use the one that looks like a block (My shrimp are in a 16g so have a different sized sponge but they come in much bigger).

I wouldn't use a circulation pump with shrimplets in there. I ordered the spray bar for my output and that would probably be fine for yours too. What else is in your tank? Or is it 75 gallons of shrimp heaven?

Hmm. Ok. Well that explains why I could not find what I was picturing. I think I will end up with a Filter Max III, as it looks like it will block fry & shrimp, and says it should be good for over 200gph (the XP4 is rated at 190gph). I'm being picky about the appearance of things, so I'd prefer not a random looking block. I was going to get a Hydor inline heater for the same reason, but saw too many mixed reviews on them.

I will avoid the circulation pump, as I figured it wouldn't end well. And I guess I need to see what all comes with the XP4, as I thought the spraybar was included. It was my initial intention to use the spraybar at one end & the circualtion pump at the opposite corner.

As far as tank mates for the spattering of shrimp, I will have nerites, guppies, mollies, some loaches, dwarf rasboras, maybe small tetras and possibly some other of the peacefull small varieties. There will be a decent amount of planting, rocks & wood as well. I'd like a splash of Gardneri Clown Killifish, as they supposedly are shrimp-friendly, but I have my doubts about that one. No matter what, I am researching the death out of fish traits.

Can't blame you for being picky! I am pretty picky myself.. Now I guess it's me with the ridiculous filtration .. I know for sure I have the XP XL and it's rated at 450gph.. So I'm not sure which one you're getting. I thought mine would come with a spray bar..was disappointed to find it didn't!

I have a hydor heater on another tank(my 72g) and love it but it's the regular hydor submersible heater. Hydor is a pretty good brand to go with I just think those reviews are pretty scary for the inline one. There are plenty of better ways to hide your heater.
