timbruun Posted February 21, 2013 Report Share Posted February 21, 2013 Is it a good idea to reduce the output on the FX5 to 5/8" so I can use the Hydor 300watt ETH? What is the best way to do it since the FX5 hoses are ribbed? Or is it a better idea to get the Eheim 2075 instead? Quote Link to comment Share on other sites More sharing options...
jvision Posted February 21, 2013 Report Share Posted February 21, 2013 I don't used the ribbed hoses on one of my FX5s - just PVC (flex for the first few inches to get it out the back of the cabinet, then hardline into the tank). You could use a 3/4" PVC return and just reduce it thru the heater. I did that on an Eheim a few years ago. Reducing the output is fine (up to a point), but you should never reduce the input.

timbruun Posted February 21, 2013 Author Report Share Posted February 21, 2013 (edited) Is the 5/8" going through the heater ok then? Is it going to be hard on the pump? I guess the other option is to have a split on the output and have one of the splits go through the heater and the other with a valve to restrict a bit but still have flow. Or 2 inline heaters, one for each split and send to each end of the tank. Can I just use normal clear 1 inch hose then and still use the same intake and output nozzles?

jvision Posted February 21, 2013 Report Share Posted February 21, 2013 I have a single 3/4" return, and its been running for a few years w/o problems. I would probably run a 3/4" return and just reduce down to 5/8" for the heater. However, I do like the split idea. I remember a thread on MFK where the guy had 2 or 3 3/4" returns from his FX5.

timbruun Posted February 21, 2013 Author Report Share Posted February 21, 2013 So if I go with the FX5, what is the best way to hide the intake while not sucking up sand or snails? Quote Link to comment Share on other sites More sharing options...
jvision Posted February 21, 2013 Report Share Posted February 21, 2013 I have a 10" length of PVC that is capped and slotted on one side placed about 2/3 down the tank. I had it closer to the bottom, but would always get a filter full of sand. Quote Link to comment Share on other sites More sharing options...
noot Posted February 21, 2013 Report Share Posted February 21, 2013 sorry but i am going to jump in on this discussion. i am going to build my own spray bar and would like to hard pipe my fx5, but do you just use regular pvc cement when you glue the pvc pipe together, or is there something special i need to us in order to not contaminate my water? thanks Quote Link to comment Share on other sites More sharing options...
jvision Posted February 21, 2013 Report Share Posted February 21, 2013 Yep. Just PVC glue is good. There's a product that is a primer and glue in one - I think it's called "Red Hot Blue Glue" Quote Link to comment Share on other sites More sharing options...

timbruun Posted February 21, 2013 Author Report Share Posted February 21, 2013 Do you have a sponge on the intake also? Quote Link to comment Share on other sites More sharing options...
