Hi folks I am working on a program (excel spreadsheet) that calculates all you salts for you based on your tank size, WC% and your local water report. You enter your dosing volumes/container size/frequency etc You select your regime/product then pick your salts you plan you use, and presto its...

Hello all! I am new to this forum but not really, I've been using it for guidance for about two years since I began this journey. I have a 125g planted high tech community tank (had, rather). I had a mishap about a month ago where I did my regular 50% water change on Sunday. Except this time all...

Hi Gurus, I am not so beginner in terms of aquarium experience but recently just plunges to have a planted tank set up for my discus. I want to know what should be my paramaters in Nitrate, Phosphate, Potassium etc for me to have 2x a month of 50% water change. I do not know if this is better...

Hey all, I recently bought a TDS meter and measured my tap water at 80 TDS. Just before a water change a week ago my TDS was at 260 ppm. I changed 50% of water, and as you'd expect TDS was around 170ppm. A week later, I did another 50% water change but now TDS is at 200, so it is steadily...

I was wondering about raising my GH during water changes. The water in my tank is at 7GH (due to seiryu stone). The water out of my tap is 1GH. If I change 5 gallons of water on a 20 gallon tank what should I be raising the GH to to maintain a stable environment? I usually dose my tap to...

Hi everyone, I am in the process of setting up a 500 liter tank with CO2, high light and EI dosing vía doing pumps. My pump has 4 dosing channels and I started thinking about running an additional channel through a line that winds underneath the substrate. It would use the same macro...

Hey Guys Hope you are doing well, I just need help about nitrogen fertilizer for my tank in my country nitrate is banned can I use urea in my tank if yes then how much to dose? Thanks.

The plant bug has spread a bit for me, and there are now 4 tanks in my house with plants. I’ve got my 90 pretty well dialed in, using EI, and am happy with the growth rates and the tanks health. I’ve been mixing the fertilizers in a 500ml container and dosing according to Rotala Butterfly. I’d...

Hello, just thinking about mixing my own NKP. I want to try to add some NH4NO3 along with KNO3, but wanted to know how should I calculate the real equivalence of NH4 to NO3. I use to make NPK without NH4 and usually had a dose, let's say single spray, adding 0.5ppm of NO3 to my aquarium. N in...

My water is only about 1-2 GH. Most likely 1. Equilibrium states to dose 1 tablespoon to raise my GH by 3. I seen some say there is a lot of potassium in equilibrium. Will this cause any issues? I'm trying to raise it because of a suspected calcium deficiency

Hi! This is my first post on this forum and I'm really glad I found it. This place is great. I recently started EI dosing on my tank around two weeks ago. Here are the tank's stats: 1) Rubbermaid 100 gallon tank 2) Running CO2 at around 6-7bps 3) Tank is outside and only lit with direct...

Hello Everyone, A couple of months ago i moved to a new location away from my hometown. After setting up my tank i see some plants are significantly uncomfortable so i decided to check my water parameters. I am using ground water and its literally a solution of CONCRETE..! 100 Gallon tank ~420...

I've read some articles about growing red plants. They've suggested that lower levels of N helps with keeping the plants red. I know we have to keep an eye on proper CO2 levels and light as well. I'm not trying to grow Red plants at this point. When I've tried to grow Red plants in the past the...

I'm far from scientist so hopefully someone who understands these things will help me on this matter? Looking over the link below I wonder whether I can use the chemicals I have with the addition of ascorbic acid and potassium sorbate and turn my 2 part Macro/Micro solution into one? This...

I am in the process of setting up my first high tech tank and I have a bunch of questions about water and fertilizing. My setup will be a heavily planted 55 gallon forest style tank. I plan to run CO2, RO water (I live in LA with liquid rock water) and 2x current satellite pro + lights. I...

Thanks for sharing!

I've just started to add K2So4 into my EI mix. when adding this and mixing it with RO water it fizzes and then i get small white clumps form. Is this normal? i put all salts in the container and then add water. Should the K2So4 be added first to dissolve before adding the KNo3, KH2So4 and MgSo4...

Hi Everyone Can someone tell me what is save levels of S and CL in ppm for a 100l planted aquarium. i want to use either KCL or K2SO4 to make potassium fertilizer. Help would be appreciated Thank you

My tank is low tech non co2 moderately planted with crypts, anubias, and marsilea. I figured aquasoil would be enough for ferts, but should I be dosing a small amount through the water column? Not sure which nutrients will be needed with aquasoil. I have seachem flourish, Kh2po4 and kno3. Is...
