Very HIgh GH in new tank
HI everyone, Just starting with this hobby with a small 35L aquarium. Currenty putting it through a fishless cycle as I dont want to make any fish suffer.

I have added Nutrafin Cycle plus to introduce some bacteria that I need, and will be putting a couple of drops of ammonia in to try and kick start it, however I will be waiting a few weeks forthe correct levels before I even consider introducing fish.

Current problem I have at the moment is very high GH when I have done an early water test. It is currently showing at 500ppm, and possibly more as the strip does not go any higher.

Ive looked at a few options, either buying an addtive that will soften the water, or using the peat method.

If I could ask a few questions please:

1) Can peat be purchased that can be placed in the HOB filter to reduce the GH?
2) Is it a good or bad idea to use an additve for GH?
3) What product is best to use to introduce bacteria to the tank? (i do not know anyone else who owns an aquarium to pinch a bit of gravel off them to get the bacteria going)

Many thanks

Problem solved. Just done a 50% water change with de-ionised water and thats reduced it to 125ppm from 500+.

When the fish are in and established. Ill mix tap and DI accordingley to get the same ppm reading. Our water is has a ridiculously high mineral level. Hope its not bad on my health when I drink it lol.

This is the best solution, diluting hard water with some type of "pure" water. Yu can read more on how this works long-term here:

On the bacteria for cycling issue, I recommend either Tetra's SafeStart or Seachem's Stability. Both are 100% live nitrifying bacteria. They act to "seed" the tank with bacteria.

And welcome to Tropical Fish Keeping forum, and the hobby.:-D
