If my trickle in is on the inlet to drum which obviously leads to the bio chamber is my only option the likes of a Vyair cartridge or can I get around it some way using ST crystals for one large water change?

just use a 3 pod for trickle,where does your drum flush pump get water from?? mine both take from clean side so i have a torbeck valve through overflow hole in my skimmer,but mines just a long throat wide mouth one,this just tops pond up after drums have cleaned,my drums do have a sensor on them which can operate a 24v solenoid to automatically top up but not got round to looking into really yet,andi

daft question or suggestion but looking at your skimmer is the built in overflow pipe set at height of pond,could you not use hard pipe and just put a small tank connector onto skimmer as your trickle inlet,you would still easily get basket out and your overflow would be trickle out wouldnt it,andi

Sorry the overflow on the skimmer will be the trickle out

i would of thought if you put inlet on opposite side to overflow that skimmer flow would pull trickle water down and only pond water coming in would go into overflow,andi

I would put the trickle in pipe straight into the last section of your bio near the pumps. What you don't really want to be doing is putting the trickle flow immediately before your filters- just in case chlorine got through for any reason and started killing off your bio. Having it after the filters means it would be very diluted in the pond before it could cause major harm (in the short term anyway).
I have mine just stuck into the bottom tray of my shower. Although I do have a mini-flow meter on it, I do sometimes like to pull the pipe out just to have a look at how fast the flow looks. Also handy when you want to take a sample to check for chlorine getting through the dechlorinator units. If you plumbed it in with a proper tank connector of some kind then you wouldn't be able to sample it so easily.2016 new 6000 gallon pond

As daft as it sounds you could put a tank connector on using say 15 or 22mm plastic pipe and then have a 90 piece that goes down to basket but not glue it into the tank connector then when you want basket out just take the piece out.at the rate you will be trickling in i dont think even if a bit of chlorine got thtough it would hurt.andi

I currently have my trickle in going into my drum. At the moment its not properly plumbed in but I have the bits to do it now. My thoughts were that when I am trickling in tap water it is going in very slowly - compared to the flow of the pumps its nothing - I have a dechlorinator but even if it wasn't working any chlorine is going to be so dilute by the time it gets to the bio filter its not going to do anything.
I have an added complication that when we have loads of rain water (Autumn, Winter & Early Spring) I swap over to harvested rain water. This can have high Ammonia at times so I want that going in before the filters.
Even if I didn't have that complication I think there might be a greater risk to the filter if undilute tap water was added even if near the exit. If the pumps stopped wouldn't the bio fill with tap water??I think going in to the drum is less of a risk, but I would do whichever is more convenient plumbing wise tbh.Last edited by pip895; 15-11-2018 at 10:59 AM.

Today’s the day...
Just out of curiosity, if you had a grow on tank that was indoors and insulated with thick celotex and a lid with the filters wrapped up how much would it cost monthly to run a 1kw heater keeping the water at roughly 22 degrees? Btw ASHPs are way out of my price range at the moment

Wouldn’t it be better to
Put the auto top up in the dirty side of drum then if pumps go off while waters flowing in then water would flow down the waste chute I have my auto top up sensor oase one in pond and water tops up straight into pond this way if there is any problems with a pump failure bio won’t overflow water would run down overflow in my skimmer

Running heater at low temp?
Covering the pond with polycarb should be enough to stop water temps dipping below 6C for the most...
