Juwel Korall 60L Refresh

I have now had the Juwel Korall 60L 7 months and have grown bored with the decor. Also I felt it was about time it had a proper cleaning. I went to my local fish store and bought some new substrate. White Roman Gravel and Fluval Stratum. Even though on the packet Fluval advise not to use the stratum with other substrate, I decided it would serve as the first layer for my aquascaping plans.

Something to consider when changing the substrate in your tank is the beneficial bacteria that break down the ammonia and nitrates. These will reside in the gravel and when washing out the gravel or replacing it, you will be reducing the efficiency of your tank to negate those substances. So keeping an eye on your ammonia levels will be important.

Sorry didn’t get a picture of the substrates before putting them in the tank! The Fluval Stratum was quite small round pebbles, very light too. They both took a fair few washes in a bucket to get rid of dust and cloudiness.

While I was working on the Juwel Korall 60 I put my fish in a bucket with water drained from the main tank with the filter and my plants to keep them from drying out.

After I had washed out the substrates thoroughly, I laid down the Fluval Stratum at the bottom first. It was almost impossible to get it completely clean. Then the white Roman Gravel on top gently as the Fluval Stratum is relatively delicate and can crumble. I then put in an air stone underneath and put a plate down on top of the gravel to aid filling so as not to disturb the layers.

Once the tank was filled and positioned it was a refreshing change. I’m not sure about the decor with with white gravel yet but I do plan to put some driftwood and lay a carpet of plants on the bottom, so it will be irrelevant. The tank is short on fish at the moment, but there are 11 guppies in the Fluval Edge waiting to go in. I will probably put them in once the water parameters in the Korall return to normal.

Also be careful with the light fixture, mine took  a knock and stopped working so for the second time I’ve had to order a replacement. Not cheap at £20 each since it’s a full unit rather than just a bulb. I may have to get a better fixture anyway when I start putting plants in, but that for the future. Next up I’ll be modifying my Fluval Edge lights!
