Careful that the drum washes will be adding a good 2+ litres a flush (more for the 25 I suspect) so if your septic tank is a fixed volume it's adding a large amount. If the wash liquid could be settled without too much disruption of the upper layer you could make an overflow of non-solids to the soak away and then do a regular pump out of the solids to the septic tank.

Here is my Solum 25 installed. A wee bitty fiddily getting the water level correct but it's all good now.

Never thought of putting the solum into a sump! Neat idea. I see you've got a waste sump and sump pump into the drain when needed.
Mesh sizing - moving from #100 to #400 Mesh goes smaller (500 Mesh is 25 micron), moving 100 to 400 micron goes larger.
If you want to make the skimmer more effective one option is to use a pin wheel (just simply modify an old pump impeller), then inject the air into the pinwheel which then is fed to the protein skimmer.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)

I'm really struggling to get the water levels correct. If I follow the recommendation of 347mm it starts to overflow before the wash cycle starts then it just keeps overflowing without starting a wash cycle

There's a thread on drum water levels - specifically the "yo-yo" effect the drum can have on pond levels. Your system is gravity fed so you're likely to see the same yo-yo. The drum restricts flow so the pumps empty the water into the pond and to the dirty side of the mesh. The result is a water level increase and possible overflow. Then the wash occurs and the water returns to the normal flow rate through the drum and the water level drops. If you have a auto-top up this can cause it to refill and the cycle repeats.
You need to understand how much water volume could be added to the pond in this scenario and how much the water level will rise - that rise should be set lower than your overflow.. so when the cycle is at normal flow rate you may see the water level lower than what you'd set it to.
Curse of the gravity fed drum with a pump.
I'm kind of hoping that the airlift will minimise difference in water level in this cycle.
I'm still thinking it through a little to see if there's a way to reduce the yo-yo.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)

Hate to say it Nick, but unfortunately I get the yo-yo effect running with an airlift.
I found the best thing to do with the yo-yo effect was to allow the water to find its own level where, even with the mesh on the drum needing a clean, the water level is just at the lip of the waste chute in the drum, but without overflowing. If you do that Neil and the water level in the pond is too low, you probably need to raise the drum a smidge.
Alternatively Neil, perhaps raise the float switch. This will mean it cleans more frequently but should reduce the yo yo effect.

I've not installed it yet (my spare time taken with the DIY bathroom Reno and the pond 2.0 dig). but... I just caught the filter blocked with the same issue again - the water level had dropped an inch. In my case the garden hose pops off the connectors (Gardena connectors) as it's at full pressure 24/7 and hot weather causes it to deform and pull away from the connector. Once the drum can't clean - it overflows..
The one I went for is a Triton Controls 15A 250V floating switch (Clarke sell them) but also here (seems more expensive): here at farewell I can't remember but I bought it through a different site.
The only issue is that there are lots of people with cables that the copper has fatigued, broken and then caused arcing - that burns through the plastic and so you have 230V AC to the pond.. which is a serious safety issue. So I am considering wiring it up temporarily with 230VAC until I get a relay sorted (although I wanted a low power 12V relay that is latching so the circuit doesn't consume power). Just not enough time at the moment.
I will put it on my pump AC - so that it breaks the circuit if the pond level drops. Only issue is that that filter water empties back into the pond and you get a cycle of start/stop for the pump until the water drops so much that it can't restart the pump (so it still protects).
It sounds like you want a sensor switching module - I've seen some that can power 12 or 24V sensors and then perform the switching of the mains power too all neatly - not sure of the cost though but I suspect it's rather expensive. Also half the cheaper units don't have circuit isolation gaps between the AC 230V and the switching lower power side..14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)

I just had a second look at the pumping..
Just to confirm the plumbing..
1. the skimmer comes into the sump at water level.
2. the solum outputs into the sump directly - therefore your clean side water level is the level of the pond water.
3. the input into the RDF is pumped in?
4. the level switch you have is for a gravity setup where the input is gravity fed and the output is pumped.
5. the output of the sump is pumped out?
What I think you may find happening is that the dirty side doesn't drop an trigger the RDF because the water into that side is then kept level by the gravity feed from the skimmer through the skimmer sock.
It will not detect the drum is clogged.14000l, my mutts: Chargoi (2010), Doitsu (2022), Tancho (2022), Kujaku (2022), Hi Utusri (2022)

Nick
1/. Skimmer sock is at the pond level and overflows into the suction tank.
2/. The water level in the suction tank is about 6 to 8 inches lower than the main pond with both pumps running.
3/. The RDF is sitting in the suction tank and is being GRAVITY fed directly from the bottom drain and discharging back into the suction tank.
4/. The RDF water level is just on top of the RDF waist pipe
5/. I have moved the auto pond fill into the main pond.
For the last 2 hours it has function the way it's meant to, when the screen gets dirty the clean side drops and triggers the switch to start the was cycle, the clean side water level comes back up again then slowly drops off and starts another wash cycle.
I've been sat beside the frigging suction pit all day pulling my hair out, but fingers crossed it looks like it's found its levels.
I'm heading out for dinner in a little while, if I come back and find the suction pit empty again the RDF is going in the bin.
Later
Neil

17 hours now without missing a beat. I moved the pond mains float switch back into the suction tank, that way if it decides to go tits up at least it won't empty the pond out.
I've never seen such crystal clear water.........nitrates are still a little hi but everything else is in spec, main thing is the fish look happy

Well. After several weeks of back pain and bad weather,my solum 16 and midi gravity fed units are in and working after a bit of fiddling. Will try and post some pics later

Hopefully i can do this picture buisness.I cleaned out the filter bay,then moved the drum and midi into position.I had worked out the water line would be 860mm.I put the units up on blocks and leveled up.Hoping this was the correct height.So far so good.

Its been running now for 5 days.Only been running at 50% on the E.A 20000 vari pump and its worked fine at that speed.have ramped it up to 75 and 100% but not for long
i have an hailia 60 ltre air pump which is quite loud to be fair and when this was connected to the pipe on the midi,it did seem to make the noise worse.it seems to be like a sound box.i have used 3 airstones for now and its done the trick(i have no covers over the filter chamber at the momment.)
Water quality has deffinately improved.The running water line is about perfect(half way up the waste shute) with the sensor down to just above the bottom of its limit.Have a measured 3 bar of pressure which is great.Cant believe how much algae thats going to waste too.Its certainly doing a great job at the moment.will have a little play over the weekend,inreasing pump flow ect.Will report back.Steve.

@blondie you may want to use MPDE water pipe and connectors rather than copper pipe and garden hose connectors for two reasons:
1. Copper pipes may leach into the water and it’s toxic to koi.
2. The garden hose used kept deforming and pulling away from the connectors. I’ve had several instances where to hose pipe has popped off and let the drum without the capability to flush, causing the pump fed system to empty the pond through the waste chute..

Many thanks Nick.Can you recomend a supplier.Its very vague in the Draco instructions connecting the water and air supply.What components to use
Should of e-mailed Draco really .cheers.Steve
