Ok to mix Flourish and Flourish Excel in one bottle?

My first post, hi everyone!

Iíve done the calculation to figure out how much of each I need to add to my tank and was planning to add both twice a week on. To simplify the process Iíd like to mix right proportion of each in one bottle and dose from that. Would there be any negative side effects from combining the two into one bottle on the shelf long term, would it cause a breakdown or loss of effectiveness of either fert?

Not that it should matter as my question is specifically about the effects of mixing the two fertilizers but in case anyone is interested, it is for a nine gallon cube (guessing about 8 gallons water Ė assuming you dose on water column size, right?) I was planning to mix Flourish and Excel at 3:4 and dose about 1.5mL of the combo Monday/Thursday and potassium Tuesday/Friday. The tank is in my office so I donít do anything with it on the weekends. It has been doing very well but Iíve seen some holes and browning on different leaves so I started dosing potassium after doing some research. That seems to be working as the new growth is looking good.

  • Banana Plant
  • Baby Tears (HM I think, middle size)
  • Dwarf Hairgrass
  • Dwarf Pennywort
  • Rotala indica
  • Rotala wallichii
  • SŁŖwassertang
  • Some kind of moss, maybe Java?
  • Water Wisteria
  • Ludwigia repens (I think)
  • Some kind of Vallisneria ( I think, spirally leaves)
  • Java Fern
  • And a few other plants Iím not sure on, maybe some type of Anubias and Microsorum
  • Mopani Wood decorations
  • Celestial Pearl Danio
  • Green Neon Tetra
  • Scarlet Badis
  • Ramshorn Snails
  • Yellow Cherry Shrimp
  • Crystal Red Shrimp

In short, you can mix them with no issue...and in long it actually can be of benfit. Excel acts as an algecide and fungicide, so in a micro mix which is oft to grow fungus when left to sit for too long, a mixture of Flourish and Excel can delay the growth of the fungus.

I would contact Seachem technical support. Answering technical questions about their products is what the 'excel' in.

Well, that just makes too much sense. I will do that and report back what I find.

Thank you for the suggestion.

I just read a similar question on Seachem's forum last night. They do not recommned do ing it, as the Excel will cause precipitation in the Flourish. The support tech was pretty firm about keeping all of their supplements separate until ready for use.
