Good day. I'm currently using a Hydor Professional Canister filter. I've been using it for about 2 years but it has significantly reduced the flow over time and I'm looking to replace it with the FX4. I have just one question about the FX4. Where now, I am using I believe 5/8" ID connecting from the Hydor to GLA Cal Aqua Labs 17mm influx and efflux, I read that the FX4 uses ribbed piping? Can anyone confirm changing this out for regular 5/8" flexible tubing? Ribbed piping will not connect with these glass pieces for the input and output. Thanks.
