Hello to all members, Its great to join you all. My first post and a mojor question on planted tank: How to understand dosing perfectly according to your local water chemistry ? I have read various threads and articles related to dosing but all fail to perfect it and am not able to get very healthy plants .With a lot of reading and help i am able to understand doing to a certain extent and my dosing routine and quantity is: Tank is 55 gallon which is planted not very densly , but has many varities of mosses.The tank is 45 days old. Fishes are just 5 siamese algae eater and some red cherry shrimps.(will add black neons soon). Specifications are: substrate - Laterite + sera substrate + litte peat + gravel sand. Light - Philips fluorescent x 4 tubes = 2.6 watt/gallon. 8-10 hours a day. Filter - External canister filter which has capacity of 1200 Litre/hour. Co2 - DIY co2 diffused therough diffusor. KNO3 - 40gms + 500 ml water. K2SO4 - 40gms + 500 ml water KH2PO4 - 15gms + 500ml water "Fertilon combi - 15gms + 1000ml water KNO3- 15 ml X 3 times K2SO4 - 15ml X 3 times KH2PO4 - 3 ml X 3 times "Fertilon combi " which contains the following mix: 4.0% maganese 4.0% Fe (iron) 1.5% Cu-(copper) 1.5% Zinc 0.5% Boron 0.10% Molybdenum 9.0% Magnssium 3.0% Sulphur - 10 ml X 3 times a week. The schedule is: Sunday - 50% water changes + dose macros Monday - dose micros Tuesday - Dose macros Wednesday - Dose Micros Thursday - Dose Macros Friday - Dose Micros Saturday - Rest Day The tank history is: When it was set up i was just dosing some sera fertilizer therefore i was not getting response at all. I was just dosing 2 ml - 4 ml sera fertilizer everyday also the tank was not densly planted at all.Naturally due to this the tank developed various kinds of algae and at last after around 1 month i had to redo the tank. At this point i did a blackout for 3 days and removed all the water and let the substrate dry out and gave a bleach dip to all plants, stones , and wood.Till this time there were no fishes at all. Later after i started my doing routine as stated above Java ferns and "some" plants are showing good response and are growing but still the plants in my tank are not so green and many plants have lost its colour and are showing some leaves are showing up yellow colour . Was little bit happy because some response and growth is better than algae. Even a new canister filter was installed at this stage and the siamese algae eaters and RCS were inrtoduced after 20 days of redoing the tank. Now my major doubts are that why are the plants not so lush green in my tank also the growth is also not good. Many plants are showing pale leaves and the growth is very slow. Do i need any more chemicals to be added to my dosing routine ? . My local water already has calcium in it (i can see white calcium layers when the vessels dry out in the kitchen). Therefore wat other chemicals are lacking in my dosing routine and where am i making a mistake ?? Can anyone help me out with this ???? :?
