I personally can't see the point of doing that and can't see any advantage either, when you say canister are you referring to external filters, if so it would be a hell of a job to do that on my tanks and I'm sure not many people would go down that route, I'm sure the fish wouldn't be impressed either.
It's a shame that this happens with Pet shops, some seem only to keen on taking your money, Hope things go smoother next time, While you are waiting for your tank to cycle you could research the fish you like and see if they will be suited to your water conditions, There are some Caresheets here http://www.fishkeeping.co.uk/modules/caresheets/
Hi, the treatment you mentioned was 'tapsafe' this removes the chlorine from the water making it safer for the fish,it does not put any bacteria into the water, Did you use something else to cycle the tank? The reason your tests showed No Nitrites or Nitrates was because there were no nitrifying bacteria present to convert the fishes waste (ammomia)to Nitrites then Nitrates. I have used a treatment called Bio-mature in the past with good results, it would also be advisable to get a Liquid test kit such as the API one, Test strips can be a little inaccurate, You would also be looking at about 4-6 weeks to cycle the tank. HTH.
Sorry to be the bearer of bad news, but 27L is not big enough for fish, shrimps and snails maybe. The reason your fish died is because your tank wasn't cycled, Please take a read of this article http://www.fishkeeping.co.uk/articles ... hless-cycling-article.htm All the answers to your questions are covered in that. Good luck if you decide to start again.
Hard to say without a picture but if it's planaria they are usually the result of overfeeding so a good tank clean and reduce the feeding, try looking at google images for them also look at Hydra, a lot more troublesome and harder to get rid of. As regards your Hillstream Loach, please take a look at this article https://www.google.co.uk/url?sa=t&rct= ... g2=Vc8M4QF1FT5kqNFKgVDS1Q
Hi, have you tried adjusting them as almost all combined heater/thermostats have an adjustment dial/knob on them. also what is your room temp as you are unlikely to get your tank cooler than the room, also lights when on can up temp a little. I unplug my heaters when the weather is warm so that if the temp drops a couple of degrees at night (it will not harm the fish) it gives a little more time for the temp to rise again during the day.
