glass rocks/marbles
i am not a big fan of gravel cuz i think it looks dirty, so i use glass rocks/marbles from michaels. the petsmart lady told me this would be fine...

any thoughts? i have very high pH in my tank and was wondering if they could be contributing?

do you have any shells in there ?

girlofgod 08-22-2006 08:57 PM

no..just a variety of glass marbles. i know not to put shells in there because they can raise the pH...

Have you tested your tank water for pH and than check your tap water for pH. It may just be your tap water's pH. If that was the case than nothing in your tank would be doing it.

could be some thing in on the marbels.

Marbles don't alter pH. Too much oxygen contributes to high pH but pH swings will happen anyway.
pH isn't your primary concern but GH(general hardness) and KH(carbonate hardness) are.:wink:

um...i dont have a kH tested, but my gH is very soft. i have been taking water in to be tested at petsmart as well and they havent said anything about my kH readings. they just gave me some danios and said that they would help cycle the tank and balance the readings, but i wanted to make sure that nothing i have IN the tank was contributing to high pH. thanks!

petsmart told me my water then i tested it myself and there two dif results

Some rocks like limestones contribute to high pH. Substrates will also contribute to high pH. If you test both with vinegar and if they do fizz violently, don't use them. They clearly indicate that they can raise the pH.
There are many ways of lowering pH but you must monitor that to ensure you're not lowering it beyond the capacity that the fish will not be able to adapt well. Peat, rainwater and bogwoods are a few methods I can mention but make sure that when you use rainwater, it's not coming from industrial areas where pollutants are likely to harbor in the rainwater.
Danios don't balance your water chemistry and neither do other fish.:wink: Don't be too concerned on your pH. Danios are very hardy and will survive the cycling which has many extreme changes.

I'll have to add that gravel is more natural than the glass marbles. There's no such thing as ultraclean tanks. I'd say you go for gravel rather than marbles. This will also increase their security and the marbles can cause glaring effects on the fish anyway when they reflect to the light.
