This table shows my water chemistry for my plant and fish for the past 6 weeks. From the statistics shown, the water chemistry seemed to be normal except for the nitrates in week week 1 and week 5. The reason for this could be that the amonia from the fish was too high in the water. The pH has also been stable even with the strip change from Sera to Tetra in week 4. For the past two weeks there has only been one water change for the week instead of two. This has not impacted on the water chemistry and therefore we can conclude that the systems within the water are working optimally. Algae has also formed in the water but it still did not seem to make too much difference to the water chemistry.

If I compare my water from my plant at home, to the plant with the fish, I can say that it has not grown any algae. I have not measured the water chemistry as with the fish, but did a water change at least once a week. As a result my water colour has not changed much and no algae has formed. My plant has grown lots of roots and it seems that it using more water becasue I need to top up at least once a week, that was needed before.
