Hello everyone,
Please may I ask for you advice regarding the health of my Pistia Stratiotes. I have it in a tank which has been set a few months ago, up until 2-3 weeks ago it has been growing well in the sense of shooting new plants and covering my water surface. The plants have been green but recently they have started to become yellow/brownish and some leaves have yellowed completely and have holes in them and the growing has slowed down a lot recently. It looks like an algae to me, but I have no idea what could have caused it as until now it never appeared. It seems to mainly affect the Pistia and it was on one leaf of the Anubias but I scraped it off.
The rest of the plants in the tank are doing fine, the light I have is the one which came with the tank an LED of 8w I believe and there is a smaller one of 2W which I added as a evening light. Both are on together for 8 hours and then I switch the main one on and leave 3 hours of the 2W before bedtime.
The temperature is set to 25 C, once a week I dose some Tropica specialized fertilizer in very small quantity. 30% water change done weekly with water from tap, which is quite high in nitrates (according to API test) and GH is 12 and KH is 16, Ph is 7.8
I have attached some photos, I will appreciate any insight or advice on what's happening with the floater and if I can help it in any way.
