the reason why my leaves have darkened is because when Hypoestes are in the shady areas for most of the time the leave colour will darken due to insufficient light. The white spots shrink if the plant gets insufficient light and will go lighter green if it gets to much light.
The water quality of the plants with bettas have been monitored over a period of two weeks now, and two sets of data have been recorded. My plant is and betta combinations is BPN1 = Blue fish, Pink Hypoeste and the fish is Non-isolated.
At the end of the first week it was found that the :
nitrate content (mg/l) was 10-25
nitrite content (mg/l) was 0
The nitrate content was concerning, but if you compare it with the Blue fish and Pink plants that were isolated the water quality was found to be much worse.
nitrate content (mg/l) was 100
nitrite content (mg/l) was 10
From theses results we can see that the water quality of the plants with the fishes that are not isolated have a better water quality than those that are isolated.
In order to improve the water quality of both isolated and non-isolated environments and lower the high nitrates and nitrites in the water, instead of doing one 20% water change it was decided to do two 20% water changes per week, just to lower the high levels in the water and in the end providing a stable water quality environment for the plant and fish.
As a result of doing two water changes. In the 2nd week it was found that for the non-isolated fishes water quality was:
nitrate content (mg/l) = 0
nitrite content (mg/l) = 0
And in the Isolated fish tank
nitrate content (mg/l) = 25
nitrite content (mg/l) = 1-5
we can already notice an improvement in the water quality.
Lets see what happens to the water quality over the next few weeks.
here is a sneek peek of my little blue betta and its home.
