One of those eheim gravel vac pro thingames? Daily cichlid clean up is powering through large volumes of water with the gravel vac idea, so, wondered about these as a way to cut down the amount of water replacements? Did ask on Facebook group, couple of responses but not enough to convince me yet on the 130 price tag?

Be great to get local views on these, good, bad, ugly?

Thanks in advance.

They have good reviews but I've personally never used one.

I would just DIY one myself if it was me, just use a normal gravel vac, stick a filter sock inside the vac, recirc the water back into the tank. When you are done cleaning, left the entrance (sucky end) out of the water so the remaining water drains out of the recirc tube, stick filter sock in the washing machine.

I did think about that, gave it a try infact but the vacuum didn't seem to work terribly well with the restriction to the flow. I might try a large grave, vac before flagging my DIY efforts though
