Frustrating isn't it ... not knowing for sure if they are worth using or not! All I can say is this, it wasn't until I switched from using the AquaSource Filter Gel to the Oase Biokick Prem that I noticed the media (particularly the PondPads) start to colour up, but that doesn't mean to say that the AS stuff hasn't seeded the media initially. Perhaps using different sorts is actually beneficial too, if they contain different strains. The only way we'd ever know how well one worked against the other would be a controlled lab-type experiment using a fishless cycle, exactly the same type and quantity of media in the same volume of water etc etc. Any volunteers?

Well I’ve use cloverleaf bio gel and ea balls and still got nitrite I’ve just slowed the pump down with a slide valve and turned the air pump down see if that works

I've used EA bio balls in the past and have to say, I think the gel formulas are probably better as they do seem to stick to the surface of the media (you can see them looking blue) so if you haven't tried them, may be worth a shot. Also hated the fact they didn't dissolve totally and you were left with loads of little black dots in your media or pond!
I did the same - I have a vario pump, so would ramp the speed up and down as necessary to keep the bottom clear, but on the whole tried to keep it between 60-70%. I also swapped over my air pumps once the media was boiling nicely so had only 60 LPM on the bio section of my ProfiClear Compact. I would even turn it off periodically, esp when adding filter bugs, to give them a chance to take root. You definitely need to have your UV off when you're adding the filter aids, and it also helps if you have a lid over your bio section as apparently they thrive better in the dark... romantic little bugs11,440L Raised Pond, BD, Oase ProfiClear, Bitron 55W, 2x10k Aquaforte Varios, Skimmer to Waterblade

Did that sort your nitrite out with slowing down pump

It's really hard to say for certain, because I was trying so many things at once (less air, UV off, biokick, modest feeding), but I think it all helps and as the ultimate goal is to establish a mature filter as quickly as possible, then this multi-faceted approach is worth trying. Logically, a slower flow is going to result in more dwell time in the media which has got to be a good thing. The only downside to the slower flow was more debris in the corners of the pond, but as I've just written here, I solved that problem with an in pond pump and feeding NTLabs foods: https://www.koiforum.uk/pond-construction-pond-build-diaries/27163-bottom-clearing-3.html#post352058

400 g tub Envirex used up 200g to start then a small sprinkle each day into biochamber of nexus .
Pot empty.
I'm feeding x3 per day for a week now. No UV for nearly a month Water crystal clear, pond turning over every 2 hrs. Temp 21.
So its been about a pound a day cost.
I appreciate that the pond filter is maturing but I think that Envirex has helped mine. Todays and Yesterday. Nitrate low. Ammonia zero pH 8.1.

They were the cheapest online, give it a try mate if it shows nitrite zero even for a day it will put a smile on your face

For me they are just a gimmick. For the cost of them they need to put the nitrite to zero in the short term, and they just don’t do that (or actually anything much). The filter (and whole pond eco system) is going to take an age to mature and the best thing to help is heat to speed that process up. For me it’s all about controlling the effects of nitrite and keeping the levels to an acceptable point using salt as advised by the most experienced keepers on here. The issue then of course is increased heat causes increased nitrite problems (so there’s another battle)!
What convinces me is the level of salt used by dealers, why are they using it? Surely as they are overloading their filters at certain times with too many fish, classic NPS!Fibreglassed/5000 gals/4.5 m Tunnel/Spindrifter/Twin drums/Bio chambers/Beads/Showers/Remora ASHP

i no longer buy filter bugs , someone on here once said to its its snake oil and i have to agree, nature in time does its magic
when i first built my pond i brought loads of different brands of filter bugs , to kick start a super bead filter , i had ammonia and nitrite issues for a year , most of it was my own fault trying to mature an unheated pond at end of october , , 6 months later wasnt happy with the space/size and reduced flow of the bead filter, replaced with evolution aqua stainless steel bio chamber all spring and summer K1 wouldnt mature
i learnt that PP the media first takes away the shiny surface which then allows bacteria to easily attach to and colonise it, 4 weeks later with no snake oil added i finally had ammonia and nitrites under control
other thing to do is always have more media than needed , higher flow rates and more air than needed especially in the bio where the bugs need it most
for almost a year ammonia and nitrites have been 0
