Just a quick question
What kind of filetr do you have for such a small tank
I have 2 10 gallon tanks as med/backup tanks and I have a tetra Whisper and a Penguin 100 Bio Wheel Filter
Interested to know what you have

46 gallon tank

4 Lemon Tetras
5 Harlequin Tetras
3 Leopard Corys
3 Black Neon Tetras
3 Cherry Barbs
2 Khuli Loaches
3 Black Skirt Tetras
2 Green Emerald Catfish
1 Angel Fish

I wasn't able to find all the numbers, only that my on is 7.8. I'm not sure if that will be enough information?








I don't know the specific filter on it, only that its rated for 20 gallons if I remember right. I have it heavily baffled so the flow is very minimal.
I'll be able to know for sure when I'm home tomorrow evening though and should be able to let you know then c:

On the water, it is important knowing the GH and KH, as this impacts fish even more than pH, plus the KH will tell us if the pH may lower which would be good for some fish. Can you get the GH and KH (Alkalinity) from the water supply folks? They probably have a website.

On the filter, something very simple, and a sponge is just that. With live plants you do not want water moving around much, so a small sponge connected to an air pump (I use this on my 10g, 20g and 29g tanks) or something like the Fluval U1 which is an internal motor unit with just a sponge; I have this on my 33g.

I was able to find the water report online for 2011 but unfortunately, I've no idea on how to make any sense of it ^^;

Hopefully that will have the information you need?

I managed to find the hardness, the average is 179 so that's about 9 dGH. The pH average is 8.1, but i saw no reference to Alkalinity or carbonate hardness (KH) so I can't guess how stable the pH may be, but usually (though not always) the KH is close to the GH.

Back to the fish. As this is a small tank, it is a good candidate for diluting the water a bit. The GH at 9 is not too bad, but this is the average and if it should be too much higher that could cause problems for some wild fish from soft water. You can use rainwater, distilled water or RO water to dilute the tank.

Specifically where I am, the PH is 7.8, I was able to get that tested.

I will definitely look into RO water since I've never used it before. Do you know which fish would be best in my type of water or would using the RO basically open everything up to me?

There are a number of fish that would be fine, but our issue here is dealing with a very small tank, so our selection of fish becomes much less, and that tends to take us into mainly wild-caught species that obviously have more restricted water parameter preferences. There is usually some degree of adaptability, but this varies with species; and I am one of those who remain convinced that fish will be more likely to live healthier and thus a more normal lifespan for the specie if I pay attention to their parameters.

Mixing RO with tap is how you do it, as this allows some mineral to remain. I would myself start with maybe 1/3 RO mixed with 2/3 tap. Mainly to get the pH a bit lower. Have a browse of the profiles, looking for "dwarf" species among the cyprinids especially. Ember Tetra is about the only tetra (characins) and there are a couple anabantids.

I'll definitely look into it then and see what fish I like best and if I can give them the correct parameters


thank you for all your help!
