Bacteria Maybe?

    Over the course of about a week or so, the gravel in the tank is starting to get a yellow covering over it. Also my fake plants are getting discolored. Pictures below

    Its algae, we can’t see bacteria without a microscope :p

    Is it normal for a tank to have it on the gravel? Cause it looks weird lol

    Congratulations, you have diatoms (brown algae). These are usually present in newer tanks. May I ask what your feeding, lighting, and water change schedule is? Also, how old is the tank?

    Congrats, again! That is the pain of having white substrate. I went through the same thing with my 100g filled with white substrate. How old is your tank? As mentioned above, brown algae is usually seen more often in newer tanks. Also consider your lighting and water temp. All these could factor into the growth of it.

    I've had success in managing the diatoms with a handful of Nerite snails, as well as ramshorn snails. Also, I've added some pretty decent sized anubias plants
    Not sure if that had anything to do with its growth, but I know the snails do an amazing job!

    The lighting I use came with the tank so I am not sure but the tank is a 20g TopFin from petsmart. I have had the tank for about a month and a half which is why the water is a milky white which I did some research on about bacterial bloom. I have a live Amazon Swords plant that I put in just yesterday giving it root tablets. I have 4 corys, 1 angelfish, 1 hatchetfish (others sadly died), and 4 neon tetras. I am planning on adding much more live plants and changing the fish to be: 4 corys, 6 cherry barbs and 1 paradise fish. The temp is around 78-82F. I feed the fish flakes and sinking pellets for the corys which they devour. I change the water 15-20% weekly adding room temp water with a dechlorinator added.

    Try using some stress-zyme (api) or stabilize (seachem) whenever you do your water changes or add another fish. This will add beneficial bacteria to your tank that will help clear up the bacterial bloom. The fact that you probably have that is a good sign your tank is in the process of cycling.

    I was planning on adding in new fish in the next week or so. Thank you for the help!

    You should test your water and make sure the tank is cycled before you put more fish in it....

    I have been testing the water weekly and it has been constant for the past month with 0 nitrates and nitrites, 7.5 PH and I am unable to test ammonia.
  11. FahnFishlore VIPMember

    That's the most important thing to test for lol, sounds like you're using those unreliable strips...

    You always get 0 nitrites and nitrates in the beginning because your bacteria that convert those from ammonia haven't established a big enough colony yet. Definitely get your ammonia tested.
  12. LefkyValued MemberMember

    Is there an ammonia test that you recommend? Reliable and not too expensive?
  13. FahnFishlore VIPMember

    API's liquid test kit, hands down. Really, you'd be better off just getting their Master Freshwater Kit. It's a bit spendy but lasts forever and is much more accurate and reliable than strips.

    Alright I will look into it thank you! When do you suggest I add in more fish?
