gold glass and "seaweed"
Hi there,

We set up our first tropical fish tank about three months ago. We were unlucky and got our first batch off fish with a disease which slowly kiled them all off but one. We were given a treatment from the pet shop which seemed to clear things up we then waited and added little tetras and guppies (I think that's right).
On a weekly basis we add the solutions to the water which is meant to keep everything in balance and the water is gradually changed.
However two weeks ago the tank started getting green seeweed type things growing from the ornaments and I realized the remaining fish from the original batch (the one with the illness) had died. I removed the plants with the "seeweed" growing from them , have not replaced as I wanted to wait until my husband returned (hes away for 6 weeks on business) to fix things. The fish still have ornaments and one big plant remaining. Now however some little gold markings are discolouring the glass and seem to be taking over quite quickly. Initially I thought they were finger prints on the outside from my Daughter but it seems they are definately on the inside of the glass and are now going around the whole tank including growing on the filter. It just looks dirty rather than a plant or anything.

Also upon closer inspection I have found that there are now little bits of "seeweed" starting to form on the other ornaments and they have become discoloured also in this brown/gold dirt and also there is a guppy on the gravel laying on its side flapping only a little.
As you can tell I am pretty clueless, I really want my fish to be happy and my tank to look nice so can you please tell me what to do ??? I am full of cold at the moment so can't get to the pet shop.
Also on a random note can you tell me if me touching the water could be harmful to me as I am heavily pregnant and concerned about cleaning the tank too much in case I manage to catch something... probably sounds silly but Id just like to put my mind to rest

Many thanks

Your first fish most likely died do to the tank not being cycled, not a disease. The cycling process kill many fish and permanently damages the ones that do survive. Any stable tank needs weekly water changes. Your tank is showing this. No products or additives can take place of any regular maintenance. You have algae which is a clear sign of a tank suffering from neglect. It is easier to keep algae at bay then to remove it once you have it. Taking proper care of the tank buy doing regular maintenance (water changes, gravel vac, filter cleaning) will fix your problem along with physical removal of algae. There is no instant fix. It will tank a while to make the tank algae free.

Your tank won't hurt you/make you sick at all.

What did the store give you to "keep the tank balanced"?

If you're adding in all kinds of chemicals, your tank is far from balanced.

I would agree that it's a n ammonia/nitrite issue-
The only thing catching me off is that the guppy is affected the worst- normally guppies are the last thing to succumb to ammonia or nitrites... Unless it's a "show guppy" with the really long finnage.

As far as the gold, I have no idea...

I do think that (sorry) removing the plants could have thrown the tank out of whack a bit.
Algae is a nuisance, but not harmful.

Bacteria in the substrate and filter break down and convert ammonia and nitrite into a less toxic substance called nitrate. Nitrate is removed with water changes.

If you have life plants, plants compete with the bacteria for the ammonia- and the plants win. Your bacteria levels will be slightly lower, because the plants are absorbing some of the ammonia.

Unfortunately, if you took out a large number of plants suddenly, you left a void in the ammonia usage... It may take a while for the bacteria to populate up to a higher level to convert it all.

Again, if you could test the water parameters we could know for sure, but without evidence to the contrary I'd assume it's nitrite or ammonia.

What do you add to the tank? Easybalance?
