Dear Tom/ Plant Guru Team
Recently a friend of mine has setup a tank which is 2 months Old.
100 Liters tank. Light is 110w PLL, Full spectrum color 5400, with CRI > 90. (Osram 954). 10 hours a day with timer
Water Hardness 150 ppm as CaCO3, pH 6.5 to 7.0.
Pressurised CO2, 2 bubbles per second thru a reactor. Filter Ehiem 2213.
Substrate
Bottom Layer : River Silt + Humus mix (10%) - 1 to 1.5 inch
Top layer : Washed silica gravel.
Mulm from an old tank was added.
Fertliser dosing : NO3 - 3 to 5 ppm, PO4 : 1.0 ppm, K : 6 to 8 ppm, thrice a week
Micro mix solution with 8% iron : three times a week to maintain minimum 0.1 ppm iron.
Problem
HC is not growing at all but not dying either. Some leave are truning brownish/Yellow.
Star Grass is growing normally but new shoots are whitish/yellowish, The whole plant apprears unhealthy/yellowish.
Glossos new shoots are yellowish and appears unhealthy.
Hygrophila Rosenervig, Hydrocotyle verticiliata and Mosses growth are good and appears healthy. Leaf colour is green and Rosenervig is red
Blyxa Japonicas after initial hick ups are now settling
What could be the problem with particulary star grass, this plant is growing rapidly but unhealthy. Is it because of water hardness or anything else. The micronutrient mixture used contains excess copper in chelated form.
Green Spot Algae can be seen on the glass.
Why are the plants showing differential growth and what can be done to get an uniform growth
Thanking you in advance.
