christinenha Posted December 7, 2014 Report Share Posted December 7, 2014 Okay, I hate to have to ask this because it's going to make me look like a total idiot, but I'm thinking of making an HMF for my newest 20L, and I know there needs to be some sort of pump to pump the water up the tubing. Is this the same kind of pump that people use for the air bubbles or is this something different? Quote Link to comment Share on other sites More sharing options...
mlsthuy1 Posted December 7, 2014 Report Share Posted December 7, 2014 (Hamburg Mat Filter). I made so many DIY filters, time for a new one. Quote Link to comment Share on other sites More sharing options...
mayphly Posted December 7, 2014 Report Share Posted December 7, 2014 Yes it is. The bigger the air pump the more flow you'll have. Just connect the tubing from the pump to the uplift tube. There are some good youtube vids on hmf's. christinenha, Soothing Shrimp and EricM 3 Quote Link to comment Share on other sites More sharing options...

mayphly Posted December 7, 2014 Report Share Posted December 7, 2014 No problem!I I keep on wanting to set up a tank using an hmf filter but always end up with an hob. One of these day!! What are you keeping in the 20L? Quote Link to comment Share on other sites More sharing options...
christinenha Posted December 7, 2014 Author Report Share Posted December 7, 2014 I was thinking of CRS to start. Then some TB/Mischlings. =) mayphly 1 Quote Link to comment Share on other sites More sharing options...
Shrimpie Posted December 7, 2014 Report Share Posted December 7, 2014 You can get some great CRS from Mayphly. I us a HMF - I love it. Easy to set up and keep up. I use a 300 air pump - but I installed a valve in the airline to turn down the flow. It was too strong. Shrimp seem happier now with not so strong a flow. mayphly and christinenha 2 Quote Link to comment Share on other sites More sharing options...
Shrimpie Posted December 7, 2014 Report Share Posted December 7, 2014 This is where I got my filter - came with tubing, 45 ppi mat - total of $20 - worth it. Got the 300 air pump for $8 from Dr Foster & Smith http://www.swisstropicals.com/library/mattenfilter/ EricM 1 Quote Link to comment Share on other sites More sharing options...
OblongShrimp Posted December 8, 2014 Report Share Posted December 8, 2014 I use HMF filters on most my tanks too. I really like them! Quote Link to comment Share on other sites More sharing options...
h4n Posted December 8, 2014 Report Share Posted December 8, 2014 What PPI foam do you guys use? I got 3x 10g i'm redoing and thinking of changing the filtration part up a bit haha Quote Link to comment Share on other sites More sharing options...

christinenha Posted December 8, 2014 Author Report Share Posted December 8, 2014 Awesome info! Thanks, everyone! I will be purchasing the 45 PPI kit for the 20L. It's only $24, so not bad! =D Quote Link to comment Share on other sites More sharing options...
christinenha Posted December 8, 2014 Author Report Share Posted December 8, 2014 I'm going to add a spray bar to it (pvc tube with drilled holes and closed end) to reduce (or rather evenly distribute) the flow into the tank. Hopefully the shrimp will be okay with that.=) Quote Link to comment Share on other sites More sharing options...

littlebirdie Posted December 9, 2014 Report Share Posted December 9, 2014 I saw something on pinterest (I think) where they used the parts of a double sponge filter..you know the large one with two moveable arms with black ridged sponges on them..and took off the sponges, cut a slit into the thick foam, inserted the filter except for the very top where it bubbles, glued it shut so shrimp would not get in and you have a giant sponge/hmf type filter. I think I am going to do that and modify it so it can be a tank divider/filter. Good luck with the new tank! Soothing Shrimp 1 Quote Link to comment Share on other sites More sharing options...

The HMF intakes water through the entire piece of foam. Inserting a hacked sponge filter intake into the foam would concentrate the intake to the two places where the initial sponge filter foam was, not using the entire surface area of the sponge for filtration.

EricM Posted December 11, 2014 Report Share Posted December 11, 2014 agreed. I'm setting up some 40B tanks with a hmf divider. swisstropicals is putting 2 holes down the center of the 30ppi foam so i can have 2 pipes. 1 for each side of the tank. hmf's are by far the best way to save $ and have simple but amazing setups.

littlebirdie Posted December 11, 2014 Report Share Posted December 11, 2014 I can't find pictures of this anywhere now! I wasn't clear about it by saying it was a hmf/type filter. I was referring to the tank divider type of sponge in it and not that it was really an hmf filter. I do see the point of r45t4m4n about concentrating the intake. Point taken. I like bostoneric's idea of making the two holes in tank divider. Would love to see a photo of that set up when it is done. EricM 1 Quote Link to comment Share on other sites More sharing options...
