Update

After cleaning and restarting the tank with new plants etc. it has now been running 5 days. I let the tank cycle for 24 hours using the filter that I had kept wet and added my Siamese algae eaters and neon tetra plus my one year old Sail-fin Pleco.

I am keeping a watchful eye on the water quality and so far there have not been any spikes of ammonia, this is still zero. All the other parameters are good but I intend to change about 10% of the water tomorrow and later in the week as I have to go away for ten days from next Sunday so I hope it doesn't give me any problems.

Any suggestions about leaving tropical fish during a vacation would be appreciated. I do have an automatic feeder by the way.

Big water change before leaving and a big water change upon returning.

I'm off out to get some more plants and maybe a C02 kit.

CO2 kit? Any particular reason that you think you need this?

Simple bio wheel and C02

I have read that C02 is good for fertilizing the plants and if the plants grow well there is less chance of algae starting. I have used a Dennerle C02 BIO 120 which cost about 35€. not an expensive set up. You can see the top of the C02 diffusor on the left.

I have also attached a photo of a simple bio wheel that I have just started to use. I have had it some time and wondered if anyone else has used one.

I understand from the original info that when it is attached to the filter outlet, the flow of water turns a small turbine which is geared to slowly rotate the sponge approximately one turn every 45 seconds in my case, I think it depends on the flow rate.

As the sponge rotates it picks up floating plant remains and uneaten food and works as a bio filter as the food degrades in the sponge. Apparently it also adds oxygen by breaking the surface and trapping air in the sponge.
The outlet had a deflector that moves the water in different directions.

I would think that the rotating sponge benefit of breaking the water would counteract the CO2 diffuser as disturbing the surface serves to off gas CO2.

I see CO2 tossed around here and there, I know the benefit to the plants and all, but too often it seems people are adding diffusers or CO2 supplements without knowing whether it is needed in the first place or is in a tank where the water dynamics will eliminate the benefit anyway.

Proper lighting and adequate fertilization can go a long way before CO2 NEEDS to be used.
