After aimless flitting from one easy fert brand to another in my low tech tanks I would like to find a product that works at reasonable cost and stick to it! ;)

And Im looking to get a co2 system in my main tank so a suitable product for a high tech setup too is needed also.

So what I would like to ask is the title^^:D any advice is welcome.

Is the Pope a Catholic ? :D
Depends on the size of tank as well i guess.
Whilst i have & use dry salts because they're cheap,on small tanks sometimes i use TNC complete, mainly through laziness.Just squeeze & pour.

Hi all,
Because I have very heavily planted tanks, which I only feed occasionally, I use the same fertiliser for both tank and house-plants, and this tends to be what ever left over soluble feed was cheap in Wilkinsons. I wouldn't recommend this approach in other circumstances.

The problem with most fertilisers, even "slow release" ones, is that the nitrogen component will go into solution fairly readily in tank water. Nearly all nitrates are highly soluble, and the one that gives you the "most bang for your buck" (35.5%N) is ammonium nitrate (NH3NO3). This is highly soluble and disassociates into NH3/NH4+ & NO3-.

A very robust system (high plant mass with floaters or emergents) and a lot of oxygenation may be able to deal with the sudden increase in ammonia, particularly if the pH is below pH7, but in other circumstances toxic levels of ammonia may result.

Hi all,
I just happened to find myself at a loose end in Bridgewater shopping centre on Wednesday, and I popped into the local Wilkinsons. They have a "Wilko Every Day Value Plant Feed", where the nitrogen content is all urea (CO(NH2)2) and 46%N).

The urea will be converted to ammonia (by micro-organisms with the urease enzyme), but it is still a safer option for livestock than ammonium nitrate (NH3NO3) where all the ammonia will go into solution in one big hit.

If you did have the combination of a tank with a very large plant load, no aversion to risk and a severe shortage of money (£1.15 for 500ml), it might be a viable option as a fertiliser for the "Duckweed index", because you would need a very small amount to get a greening response.
