Re: How low is too low for KH

Hi all, The 8 hours for the oase 650 is because it is the second filter and used to supplement the juwel filter bioflow L stack as the standard juwel set up has less than 3x turnover for a 350ltr tank at 1000lph as well as only being specified for tanks upto 60cm. OK, as the others have said, you ne...

Hi all, Tank looks good. Filtration standard Juwel rio stack, foam and ceramic media full time with oase 650 biomaster canister filter again with foam and plastic balls operating 8 hrs per day. So possibly overkill on the filtration but you can never have too much can you???? I think we mainly tend ...

Re: How low is too low for KH

Hi all, I use RO water in a medium planted and stocked 350ltr tank which is currently at 3dkh, everything seem happy and parameters are 0 ammonium, 0 nitrite, 0 nitrate and are consistent between my 15% weekly water changes.

Hi all, .....Another thing, you'd lack the food source that makes these sites popular with the fish - the high abundance and variety of invertebrates feeding on the plant matter, which are then food for the fish.

Re: Looking for a new biotope to model? How about a floating litter bank habitat?

Hi all, While such a tank would be very intersting, the problem would be the decaying organic matter. That is, the constant worsening of water quality. In nature the system is large, our tanks are relatively small, even a large one. I agree with @Bas Pels, you would need to find a leaf that was very...

Hi all, I also tried a bottom with sand, and the result was the same like in the past (disaster after disaster). This approach simply doesn't work. The uneaten food remains in the sand, it accumulates in the tank, bacteria and protozoa multiply even faster, and as a result, the fry die faster as wel...
