I recently bought a one year old albino Axolotl from a pet store, and have had the aquarium going for 3 weeks now. Ive been doing 50% water changes every 3 days and only put food in a dish for my little guy so the food is contained and is easy to clean any left overs. The last water change I did I used warmish water from the tap at about 21 deg. C. (70 deg. F.)(the same temperature as the tank water) I then added the appropriate chlorine remover in the bucket before adding it to the aquarium. This week I have noticed this white algae looking stuff coating all of the river rocks and plastic plants in the aquarium. It seems to be taking over. Today I did a 50% water change and sucked out as much of it as possible with my substrate siphon and I could not believe how much was in the river rocks. Even with the amount that I sucked out it barely made a dent.
