With the 2HR Aquarist APT-EI, the famous nutrient dosing approach pioneered by Tom Barr is now available in a ready-to-use concentrate that removes the guesswork from trying to recreate this powerful and sometimes elusive formula.
Dose 5ml per 100L 3 times per week or 2ml per 100L daily.
Buying the nutrients separately easily add up to US$75+. A 500ml bottle of APT costs US$24.99
100% comprehensive Macro+ Micro formula of N, P, K, Iron and Traces in our proprietary Capstone RatioTM.
Try it for 100 days. If it doesn’t work, get a full refund. We are aquarists too and want the best for you.
Plants grown the 2Hr WayTM using APT display a unique richness and form.
We developed APT because we could not find any existing product that met our needs.
Healthy plants, happy fish, algae-free.
As aquarists ourselves, we say ‘whatever works’.
The right performance fuel just makes it easier and (we find) a lot more exciting.
+ Essential Trace Minerals. Importantly, in the right amounts.
You can buy these 5 individual components (e.g. Potassium) for around US$15 each.
5 x $15 = $75.
Good flow, bio-filtration, the right plant mix, water parameters etc. all matter.
That is why we pair it with the internet's most comprehensive resource on planted tanks, right here.
