Don't resort to character assassination, same goes to you @TwoTankAmin
Excuse me, but I do not insult people on forums nor have I done so here. However, I will go after bad ideas. Nowhere in any of my posts did I attack the OP personally. . Nor did I attack C. either. C. Breeze makes a lot of assumption about me and how I do things. C. has never been here to see my tanks, not bought any of my fish and has never met me.
I almost never test any of my tanks, I have no need. The one tank where I have very acid parameters and tea stained water I do use a digital monitor which continuously shows Coductivity or TDS, Temperature F or C and pH. I need to maintain the parameters in the tank well below those of my tap. It is also difficult to do color based testing when you have stained water.
And then there is the need, on occasion, to run a dry/rainy season to induce pleco spawning. Before I got my RO/DI unit, I used my tap for the rainy. To create the dry season I increased the TDS first by running crushed coral for 24 hours in a H.O.T. Magnum carbon chamber on the changing water. After thatam I added Epsom salt and a pinch of baking soda, technically all chemicals I am adding. I raise the tank TDS from the 83 ppm of my tap water to about 175 ppm over almost three months. At the same time I am gradually raising the water temp, to the low 90sF. Here is the thing, many of the fish in the Amazon basin contributaries are subject to seasonal changes. They thrive on them and the onset of the rainy season is a pretty marked change in temperature and conductivity rather rapidly.
I drop the temp from the low 90sF into the mid 70s in two large water change done over two or three days max. This doesn't harm the fish, it hopefully, causes them to spawn. I once had a heater malfunction in a tank and the water was heated to 105F. It killed the discus pair, it turned the rummynose tetras to mush, but all of the L450s were hunkered down in their caves and alive. They spawned a few weeks later. That was when I learned that many of the hypancistrus were almost "fireproof."
For those who have never visited Swisstropicals, the owner is a PH.D. and lifelong fishkeeper. There are some great articles there. One of the points he makes is that many of the things that plants and microorganisms need in nature are found in the water because it contacts a lot of things that dissolve in it. Plants use many of these. However, for many our tap water may not have the correct amounts of things or may even lack some at all. Many of these things most do not test for- magnesium, calcium, zinc, sulpher etc. Many are trace elements or minerals. In such cases we must add them for the plants to thrive.
I learned plant keeping more from the Tom Barr school of planted tanks than anywhere else. I have always followed his basic EI method except I do not do twice weekly water changes and refertilize. I change at least 50% weekly and that is also when I dose my ferts and Excel. Every three months I fertile the substrate woth Jobe's Fern & Palm spikes. This works fine for me but it may not for others. Here is an anubias that needed to be bleached which I pulled out of a tank.
Anyhow, to keep the peace in this thread this will be the last post I will make. I can already hear the cheering..........
