Fishless cycle is just not working, guidance needed....
I'll keep this as short as I can but, as the title says, my fishless cycle is not working; I am not getting any Nitrite at all.
I have a Fluval Roma 125 with an external filter (Oase Biomaster Thermo 250). I went for the best canister I could afford in case the tank gets overstocked. Inside the canister is fine sponge in the pre-filter, then I've re-done the trays so that the bottom one contains blue coarse sponge that came with the filter; the next tray up has fine red sponge with a separate fine black sponge on top (it sort of looks like an egg carton in that it has raised surfaces sticking out). The last two trays contain roughly 1.5 kilos of Biohome Ultimate.
Long story short I got the tank filled and operational and put Prime in to treat the water, a day later I dosed the tank with Kleen Off ammonia to roughly 4ppm, waited 3 weeks and nothing happened. I chucked some frozen bloodworm in after they had thawed but then realised the ammonia would spike higher so I did a 50% water change but left the bloodworm in. I dosed the tank with Prime again, then the following day I tested the tank and the ammonia was down to roughly 1.5ppm. I re-dosed the tank with ammonia to get it back up to roughly 4ppm; that was just over a fortnight ago and still nothing is happening.
I'm getting impatient because it just doesn't seem to want to work. The temperature is set to 26 degrees constantly. I thought putting bloodworm in would force it into action but it simply isn't happening.
Just wanted to update this with progress and a question...
It turns out the noise from the canister IS the thermostat on the heater, not trapped air, which is what I thought due to the consistency of the noise happening every 20 minutes exactly so I'm pleased.
My question though now is I'm fishless cycling with Ammonia and it's been 9 days but I'm yet to register Nitrite. I've dosed it to roughly 3ppm and I was expecting to at least see some progress by now. Is there a general timescale for Nitrites to appear?
I’ve been listening out for the noise and it actually does it consistently, roughly every 20 minutes which is really strange. It can’t be the heater turning on or off because it is far too loud to be that so I’m not sure what it is.
It's been running fine - had a small leak issue at one of the connectors, which I've sorted but I've noticed it makes this strange scraping or rattling sound; it only lasts for a second or so but it does it quite regularly like every 20 mins or so.
I thoroughly checked the impeller when I set it up and it was fine and I've also gently tilted the canister to displace any air and no more air is coming out - is this something I should be concerned about?
As the title states why won't it prime? It's a Oase Biomaster Thermo 250, all connected up correctly and you push down the large 'button' on top of the pre filter to get it to prime, but no matter how many times I do this the water just won't circulate through.
Both tubes have got some water in but when I push the button the water moves a little then just goes back, it just doesn't want to go any further. The filter is on the floor so well below the water line, and I've tried moving the filter to displace any air but it just won't do it.

I've never known poo be this white before, especially considering their diet, and comparing that to the other fish I have (3 Platy, 6 Cardinal Tetra). I feed them Tetra flakes and frozen food and the only fish that produce white poo are these 2 Platy. The poo is stringy in that it forms a long string before it detaches from the fish - and is completely white. I must admit that I fed them frozen Bloodworm earlier today and their poo was brown for a certain time, but then it just goes back to white.
Both fish seem lethargic at times and spend lots of time still either at the top or bottom of the tank so I know there is definitely something not right.
Ok, so I've put the last dose of treatment in today and it hasn't worked. I've noticed that a couple of times their poo has been brown but, most of the time, it's still white. I did not change any water during this time either.
Does anyone know whether the course of Parazin can be repeated? There is little information given on the bottle itself so I'm hoping someone has experience of using it. Do I have any other options at this point?
