New 60L Dennerle Nano Tank

[AdrianJames]

Hi all,

New to the forums and new to aquariums. My tank is only 4 days old. At the moment this tank is cycling...well, will be properly when I add fish next week.
I have alot of plants in there and have recently bought the Fluval CO2 mini kit with 20g cartridges.
Just wanted to know if anyone has used these and if they are any good? I know people will tell me I will go through them pretty quickly... If there is another non-expensive way to put CO2 in Im open to suggestions.
Just not making my own!

Hope to hear some thoughts

You need to fully cycle ur tank with ammonia before adding any fish!

I agree with jenjen please do a fish less cycle its worth the wait trust me.

fishless cycling is better trust me for you and the fish.you dont put any stress on the fish and risk them dying.you dont have to do loads of water changes.to me cycling with fish is cruel

Much better to do a fishless cycle. I know you may be frustrated at an empty tank but if you know the options, you really should just hold out a few more weeks.

I was one of those who did not know about the nitrogen cycle and bought fish straight away. Believe me, it is not fun watching your fish go red-gilled and get whitespot and possibly die, knowing that you could have prevented it. It takes much longer to cycle with fish as you can't let the ammonia and nitrites build to unacceptable levels, so you're constantly having to change the water. It's also a LOT of work doing daily or twice daily water changes which you HAVE to do for at least a month, possibly more, if your fish are to survive.

For a fishless cycle you can just fill the tank and pretty much forget about it, save for adding ammonia and testing it occasionally.

Adrian, I'm assuming you have filled the tank up with dechlorinated water, and are running the heater and filter pump. If I'm right, you are wasting electricity, this will be doing nothing to establish bcaterial colonies in the filter.

As others have already pointed out, there is an alternative to a fish-in cycle, which is often dismissed by LFSs. Fishless cycling uses houseold ammonia to build those bacterial colonies. There are several advantages to doing this

1) You don't have to change water daily. With a fish-in cycle, you can often find yourself doing 90% water changes daily, if you are doing it right.
2) Fishless is often quicker.
3) When completed, you can fully stock the tank immediately, rather than bit-by-bit
4) No fish die, or have their lifespan curtailes, as a result of ammonia poisoning.

Have a read of this, I would recommend the Add & Wait method. For me, it's a no-brainer, but whichever you choose, feel free to post any queries you like on the forum, and you'll get the best advice in the hobby.

+1 for the fishless cycle method.I have done both and found the fishless method much easier, quicker, more humane and better all round.

Adding fish to cycle is not very fair on the fish. 1 thing I have learnt from this site is fishless cycle is always the best option.

I was the same added my fish and lost all but 1 in 3 days. Was horrible going downstairs each morning to more dead fish

I am still on my fish-in cycle, nitrites have literally just started to go down after 6 almost weeks but I have had to change water EVERY day without fail. Meanwhile, my smaller tank which I bought three weeks later and completely left alone, except to add fish food, i've seen no ammonia or nitrites in now for several days.

Thanks all for your input! Have read through and will follow all the comments. I have had a tank before and put in fish after a week and everything went fine. I may try the fishless cycle though...if its easier.

Good to hear, its all to give better welfare for your fish and will be well worth it in the end
