fish tanks gh and kh are to low?

Question

what should i do next??? the ph level is ok though

Answer 1

Change the water and don't worry about gh and kh. As long as the ph is holding the tank is fine. If you must get Kent Marine R.O. Right and Neutral Regulator to buff it up a little. A good water change will likely boost it on up. You may have to rethink your water changing schedule. A little more water a little more often should be changed so the tank won't go acidic on you. The fish you have may have outgrown the old water changing schedule. As they get bigger they produce more waste and that's what eats up the salts that make up gh and kh. All of the filter bacteria use it too, so clean out the filter sludge, clean the bio-media in tank water only. The algae also use it up. So in short the fish get bigger eat more, make more bacteria to rid the tank of waste, more algae grow to rid the tank of the bacteria's waste and the more dissolved minerals the whole system uses up. That's why you may want to shorten the time between water changes and change a higher percent of the water when you do. That will help. Good luck to you. Sounds like you have a good system running. I'd watch that ph real closely though, if it drops below 6.6 the fish will start to suffer.
If for some reason you have very low gh and kh and a very high ph like 8.0. Then something is very wrong. Leeching toxins from ornaments or painted gravel could be the culprit. Holey rock will do this. Its a orange and white (sometimes grey and white) swirly rock, or sometimes just plain concrete colored or white with holes in it. That kind of rock does leech toxins and is responsible for mysterous fish death after 6 to 8 months of it sitting in the tank. If you have one of those remove it, they are not aquarium safe what so ever. No volcanic rock is safe to put into the aquarium. (or sandstone or limestone) Hope this helps.

Answer 2

I'd need to know more to be able to help you. Generally, if your local water is soft, then there are SOME things you can do to harden it, BUT I would personally advise against trying it if you're not a VERY experienced aquarist. Instead, consider choosing fish that do well in softer water. There are lots of awesome breeds that prefer it. Here's a site where you can select fish by water climate, among other things. And here's another where you can post questions and discuss the answers you get with experienced aquarists, who might be better able to help you with your questions.
