Re: gh levels
For living in, the GH doesn't have to be at a given level. However, when it comes to spawning there are other issues one must consider.
Bear in mind that in the wild there is a significant difference in peak levels both high and low for GH (more appropriately conductivity or TDS) and that the change from highs to lows happens fairly fast. So the fish are pretty adaptable.

What makes the common person uncommon is common sense.
Re: gh levels
so would you say gh of 3 is to low to be spawning ?? as it says ideal is 5 for them to spawn ??

Re: gh levels
It isn't the absolute levels that are critical so much as the difference between them. It is the seasonal drop in TDS/Conductivity/GH complex that triggers them. They spawn in response to the change over from dry to rainy seasons.
A few other things are also happening as a result of the change such as a pH difference, a temperature difference, a food availability difference. And all of these are heralded by a change in the barometric pressure that alerts the fish that the change is about to occur.

Re: gh levels
Please help with tds. How to lower it? I add ro water, do ro water changes. It rises to 500 to 600. Zebs are eating and looking fine but how can I lower this tds

Re: gh levels
Start by checking the TDS coming out of your ro unit. You may need to replace the membrane or other components.

Re: gh levels
Thank you sir. I kept changing the water 25% then 50% change for a week and finally I'm at a steady 200 tds.
