Water test strips for aquariums vs ponds

[amy]

I know that the paper test strips aren't as accurate as other kinds of kits, but I've developed a liking for them anyway. So far, I've tried some of the Mardel strips, but I'd like to hear what other strip users have to say about the different brands.

Here's another question: Depending on where I look, I've also noticed that some of the pond strip tests are considerably cheaper than the corresponding aquarium ones. Is there any real reason why I can't use a pond strip in my tank? It seems to me that all the chemistry in a pond should be the same as in my tank, just on a much larger scale.

im not quite sure what the implications would be of using pond test strips in the aquarium, but i would not recommend it. there must be a reason they are stated for pond use and not aquarium, and so for more accurate results i would stick to the intended use.

hope this helps.

thom336:

I disagree
Don't underestimate the power of simple market pricing. The aquarium test kits are extremely over priced. Look at other things that are "aquarium special" like silicon rubber. A small squeeze tube at a pet store can be $5.00 or more but the exact same stuff can be purchased at a hardware store for a $2.00 for a whole caulking tube. Or what about lights? Granted there are some specialty lights to be found in aquarium use, but actually compare the same type from a pet store to ones that can be generally purchased and there is a big mark up.

Amy:

The water chemistry "issues" should be the same for ponds or tanks, the only real difference between the pond strips and the aquarium maybe the accuracy. Perhaps they are produced cheaper but the can vary from brand to brand. I think one of the primary reasons pond products are cheaper is that they are sold and used in bulk as opposed to smaller amounts for aquarium use.

A number of products are sold as pond supplies that are essentially the same as the aquarium versions, except for the price. Melafix, for example, is sold in a pond version that is the same stuff, except more concentrated (and cheaper, last time I looked).

I'd not hesitate to buy pond test kits. pH is pH, whether the water sample came from a pond or your fish tank.
