Hi all,
I would like to know if Solufeed is safe for fish & also which would be safer for fish 2:1:4 or sodium free. I have aquavitro propel so can supplement Fe. Water here is soft
Probably will try sodium free initially until I get a better understanding of it all... Then maybe mix
It is like
@John q says, the two fertilisers do different things. Plants need all of the <"
~fourteen essential mineral nutrients"> for plant growth, just in widely differing amounts.
Nitrogen (N), phosphorus (P) and potassium (K), are the macro-nutrients, the elements that plants need most of, the other eleven nutrients are micronutrients, nutrients that plants need less of. Plant growth is <"
like an assembly line">, you need all the components to get a plant. <"
I'm not a CO2 user">, but I always have floating plants which have <"
access to 420 ppm of atmospheric CO2">.
2:1:4 is urea based, so could be harmful to fish if one didn't know what they were doing with it
Same again, plants can only take up nutrients as "ions", charged particles in solution. Aquarium fertilisers often contain potassium nitrate (KNO3) as their nitrogen and potassium source, because it is very soluble and disassociates into NO3- and K+ ions. Nitrate is <"
harmless to aquatic life"> (until you get into very high numbers), but ammonia (NH3) and nitrite (NO2-) are both toxic at very low levels. Urea (CO(NH2)2) contains a lot of nitrogen and that nitrogen is converted to ammonia by plants and microbes with the <"
urease enzyme">, and that is where the potential issue lies.
I'm new to DIY fertilisers, and also planted aquarium. I have set up a 300l tank plus external filter. I have used TNC complete and was looking at reviews which somehow brought me to this forum. I intend to add fish once cycle is complete and I have got used to co2 system
I' start with "cycling", in terms of the traditional view it doesn't exist and this particularly true for planted tanks. Plants are <"
much more efficient at removing nutrients"> than most aquarists realise . Have a look at <"
Bacteria revealed"> and <"
Seasoned Tank Time">
in thread about urea, a bit over my head in parts but my ph out the tap is around 6.8-6.9. I do add kh to maintain 5 - 6 dkh as out the tap it is less than 1 dkh which brings pH to 7.2-7.4 depending on amount of Co2(time of day) so urea should be less toxic and remain as amonium... I think
I like to <"
get rid of any TAN ammonia/ammonium"> as rapidly as possible.
You can also add a lot less alkalinity (dKH) than you do at the moment. You can ignore <"
pH stability"> it is a term made up by people who <"
want to sell you buffers etc">. and the "filter bacteria" don't need it, because they don't actually occur in our filters. Have a look at
@Roland 's <"
tanks and water parameters">.
