  1. Fertilizers and Water Parameters
    20 gallon long tank. Aiming for 20ppm nitrate and 5ppm phosphate. I need to put in about 1/4 tsp of mono potassium phosphate into my tank 4-5 days a week to keep it at 5ppm. It drops like crazy overnight. It's almost always at 1ppm~ the next morning. This has caused two multi-week long algae...
  2. Fertilizers and Water Parameters
    Am I correct in thinking that if I've been dosing via the EI method and my Nitrate and Phosphate is still hanging around zero, that I can increase the dosage? For context I let my substrate run out of nutrients and I'm rushing to get macros back into the tank. Algae has taken over.
  3. Fertilizers and Water Parameters
    Hi, I'm new to the forum, but I thought this would be the best place to ask about my tank. Two weeks ago, I added a larger dose of phosphate to my tank because my plants had been getting great growth with what I had added so far. Unfortunately, I added too much and green water took hold of my...

  5. Fertilizers and Water Parameters
    Hi guys, I measured my PO4 today and I realized that it was getting used up way faster than before. I measured it this morning and it was < 1ppm, closer to 0.5. :surprise: I used to get away with doing only once a week, (maybe twice sometimes) like only 150mg or around there. This would give me...
  6. Algae
    Hi, I posted on here a few days ago about getting more algae than normal, especially on my A. Reineckii. They seem to be more prone to getting algae on lower leaves than other. What I've done in the past is just trim it more often so healthy areas are getting the most light. This did help but...

    Hi everybody, I'm trying to get rid of diatoms in my 5G planted high-tech tank. I've measured Phosphate=2.5 and Silicate=4.5 in the tank. What would be the best way to get rid of the diatoms? I've read that they are mostly caused by silicate and phosphates. Should I use Seachem PhosGuard and/or...

    :help: I have a 55 gal that is 8 months old now. Until recently I had shop lights over the tank and developed a real problem with different algae because I believe the bulbs were needing replacement. While doing that, the fixture broke in my hand, so because I was unable to get another of the...

    :help: Hey Everyone! I decided I should buy an API Phosphate test kit (liquid). I just tested my 20 gallon planted tank. I have super high phosphates. 10! Man, what is the proper way to deal with this. My tap water phosphate level is 2. The fish and plants are doing very well. Fertilizers are...
  10. Fertilizers and Water Parameters
    I recently thought I might have excessive phosphate levels thanks to my city's well water quality report so I bought an API phosphate test kit. I first tested my tank water which gave a reading of about 2.5 ppm; high but not as high as I feared. Next I wanted to test my tap water for a...
  11. Fertilizers and Water Parameters
    About a week ago I got a green algae right after doing my first water change. There is no fish so I have not added any food to the tank. I decided to look for a water report for the area and found out that they add phosphate. So I was wondering if anyone has had a problem like this one and how...

    Hi, I read somewhere that Marimo Ball is a very good nitrate and phosphates remover. It's true? And how good it is to out compete others algae for nutrition? Thanks
  13. Fertilizers and Water Parameters
    So I just order dry fertilizers from aquariumfertilizer.com and they have a macro micro premixed package of Potassium Nitrate, Potassium Sulfate, Magnesium Sulfate, Plantex CSM+B. So I bought all of these but as single lbs so I can alter the mix later if I want but after ordering I noticed that...

    Hi all, I'm setting up a 5G tank with 28W of CFL 5000K. Flourite black sand as a substrate and Seachem Excel for Carbon. I'm needing a suggestion on dosing though. Plants will be glosso and Dwarf Hairgrass. I have recently purchased a mixture of Ferts online which contains 2% Magnesium Sulfate...

    I have a reef master test kit left over from my days of salt water and I'm wondering if it's ok to use this for my planted tank? Or do I need to get one specific for freshwater. For those who are wondering whats in it here is a good descriptive link to the product. Thanks ahead for the help :)
  16. Fertilizers and Water Parameters
    I am new to the planted tank world. About 4 months ago, I started up my first planted tank - 90 gallon with compressed CO2 and 4 T5HO bulbs. Ever since, I have been learning as I have gone and trying to overcome issues. Until about a week ago, I was only dosing Seachem Flourish and some...
  17. Substrate
    I'm planning on starting a new planted tank by January and redoing a current one and had a couple questions about putting together a substrate. Tanks are 20 gallon long and 29 gallon. One will be low light (35W fluorescents) and the other high light (65W + 65W for 4hrs PCFs). Eheim classic...
