While I realize air pumps are not a consideration for most modern aquarium hobbyists, they are still needed to raise brine shrimp and grow phyto. I started working with SCHEGO because I use air pumps to feed fresh air to my skimmer and I enjoy growing native plants as a hobby and most perennial, shrub and tree seeds require some time soaking in aerated water to germinate more readily. For the average hobbyist, I think the main use will be that we have an exceptionally high quality line of DC air pumps. The usual DC air pumps are really garbage, they use a rotational motor which moves the diaphragm in an elliptical pattern which results in tears and they are generally using very poor quality rubber anyway and have the performance of a wheezing hamster. The SCHEGO DC pumps have an actual driver board to produce a Hz pattern for a correct linear motor and they are all made in Germany and have replacement parts, they have the performance of a comparable normal AC air pump. What I plan to assemble and offer is the DC pump with a 12V power supply and Tunze Safety Connector as a set as an emergency back up system as no matter how you try to do it, the best prop pump will still need twice the power as an airpump, so in a critical situation, the air pump will have unequalled run time. We also have the largest in and out model air pumps for those who would like to bring fresh air to a skimmer, these have an air inlet and outlet so the pump can be inside in a sheltered location and you just run a hose to the outside to draw in fresh air, it does 350 l/hr so it would suitably sized for a 9410 or an appropriately modified 9001-9012. While it is definitely true that a scrubber will give bigger gains in pH, the air pump has no long term media costs and in many cases is enough to get you where you want.

If you are interested in an air pump let me know, we did bring in all the standard AC models as well, we have all the parts in stock too if you have an old one you need parts for. For now, they just arrived, and if you want a DC back up set I will need time to get the adapters and assemble them, the pump comes with a bare wire and so a socket has to be soldered on, but if you are a fisherman and want one for your boat for bait or want to DIY a set up just let me know. Eventually, I should have a website up for these as sets or just pumps and we have some really nice air valves, tubing, check valves and airstones as well.

Roger - I received the SCHEGO WS3 air pump and hooked it up today. VERY powerful! Impressive. This thing is built like a tank. Thanks again!
 
Thank you, I am glad you like it, just out of curiosity, what is your impression on the noise level?
 
Noise is always a hard question but I’d say it’s pretty typical for an air pump.
 
Yes, that would match my assessment, they make air pump noise but nothing out of the ordinary.
 
Where can this be purchased?
 
Got it, it shipped today. Rishma actually ordered the In and Out model, the In and Out model has a hose inlet for in and out the standard WS3 is a filter on the bottom and just an output, like the majority of air pumps. Both have the same specs, one is for a situation where you can have the air pump protected outside, the other lets you have it inside and just put a hose through a window for example. I through in a free set of checkvalves.
 
How do these compare to the Alita linear pistons?
 
In quality they are comparable, both are repairable and well made pumps. Alita pumps are larger, it depends on what you need. If you need a smaller pump, Schego, if you need a larger pump, Alita is the way to go. Alita to my knowledge starts at around 600 l/hr, Schego maxes out at 350 l/hr. If you need a 12V DC pump for a boat or a car, or emergency back up, that is another good product Schego offers.
 
Thanks for the candid response. Exactly what I was looking for.
 
Following along - I want to solve my pH problem by injecting outdoor air so figure it’s cleaner to get the InOut WS3 model and stick the tube outside the window. That said — will this be enough to raise pH on a large tank of say 500gal?
 
How do you intend to run it? Hooked to a skimmer or an airstone? A lot will depend on the water flow in the area. While an airpump is my preferred, there are a lot of variables, using outside air will help, but the biggest gains will be in late spring/early summer when things are actively growing, in areas with a real fall where leaves are dropping and decaying, you may see almost no gain in that period as leaves decaying around the house are going to create CO2. It is on the smaller side for this size tank, 350l/hr will not meet the air demand of a skimmer for this size set up for example.

I can do both - in-take to Bubble King 300
skimmer or into the sump area. However, I’m not sure that it will be enough to move the pH needle.

See pic below - I can drill a hole to the outside or snake a tube through a window, next to the fan.

I would probably look at one of the large Alita pumps for this set up, they are also very good, but I would start with figuring out how much air the skimmer draws and get a pump closely matched to that. I would assume a skimmer on a system that large is going to pull closer to 600 l/hr. If possible don't go from the stated rating as that is always air full open, minimal restriction, brand new and real world is usually at least 25% less after tuning etc.

Thank you - very much appreciated. I'm a huge Tunze fan btw, great engineering and lasts pretty much forever! In fact, I still have 2 old Tunze wavemakers (and wavebox) that were still going strong after 15 years until I switched to MP40s purely for aesthetic.

I might get this for my smaller tanks though. Thanks again!
 
Hi. Is there a distance limit on the tubing for the in/out model? I’d put it in a closet about 20’ of tubing to the outside. For the external model, how does that have to be implemented, is it weatherproof? Thanks.
