Rena filstar xp parts
 
A few months ago, I complained to Mars Fish Care, the distributor of the Rena Filstar XP series pumps. I told them that the inlet pipe should be manufactured to better specifications. There are problems with the inlet pipe. This is the part that sits on the edge of the aquarium. Now I have two of these pumps and one is a backup. Well thier cannisters will accumulate air and I narrowed the problem to the inlet pipe. This inlet pipe also has a pipe cap and the pipe cap seal is nothing more then paper. Its the same as what you would find on the inside of a ketchup bottle cap. I can also see and feel a rough edge at the top of the plastic counterpart where the seal meets this edge and is supposed to prevent air from being sucked into the inlet pipe.
The other problem is where the suction hose fits onto this inlet. The wall thickness is too narrow to support a clamp properly; be it made of plastic or metal. It appears that using a clamp and securing it tight enough so that the suction hose has no chance of slipping off creates a distortion of the plastic which allows air to enter.
So when I mentioned these two problems to the distributor; thier answer was to send me two inlet pipes. Well soon, they too failed and the cannister would start filling up with air.
How do I know that the inlet pipe is failing? Well I made my own inlet pipe out of schedule 40 pvc.
An overnight test proved me right. There was no air in the cannister.

Wow, I have 4 XP filters and my only complaint is that the intake tubes are blue instead of black. I'm glad you solved your problem - I always find it satisfying to fix something myself.

Glad to hear yours are working out well for you. I may have made my clamp too tight but knowing how vinyl hose will soften under warm temperatures makes me feel uncomfortable If I did not tighten up on the clamp. If a hose just has a snug fit, it may expand enough to slip off and there goes your living room rug.

How warm do you keep the tank?

rjordan390 07-29-2012 01:34 PM

Between 76 and 78 degrees F.

I am missing a clamp or two. That is not warm enough to have that kind of an effect on the tubing, IME.

I like to plan ahead. If I go away for a few days and my air conditioning breaks down, then the aquarium temperature could easily reach over 80 degrees.

My tanks (unheated) are all over 80 for the summer.

I have had 6 of these filters and currently have 4 running and not one of them has ever had air sucked into it. Everything worked right out the box and has been since I bought them.

Good for you for solving your problem though :-)

Then my fear of the hose slipping off must be unwarranted because the hose itself must be better quality then what one finds in Home Depot. When I had a 120 gallon reef tank with sump, I was using thier clear vinyl hose from my overflow to the sump and I noticed that it was starting to collapse where it was touching the edge of the sump. I find it easier to replace this hose with the type that has been reinforced with line rather then try to solve a way to prevent the collapse. The reef tank was running at the same temperatures.
