Hi! I have an Oscellaris 850 canister filter, however this afternoon I realised it had stopped working. Luckily I had a spare Interpet PF2 filter in the cupboard, which although isn’t designed to work effectively in a 150 litre tank, should do the job. I transferred some of the sponge from the canister into it. I also took some of the glass media out of the canister, and have put it in a separate PF Mini alongside to help. I’ll contact AquaOne tomorrow, but wondered if anyone had any tips in the meantime. Is it worth me ordering a spare filter in the meantime, or should the current setup work? Thanks!!
