    It works

    Seen improved growth on the anubias since using APT Zero on the low tech, low light tank. Have to adjust the dosing to about half and 50% water change weekly to slow down algae growth whilst waiting for the tank to rebalance.

    APT-C to APT-Zero

    Transitioned to APT-Zero as I’m getting wayy too much growth & could barely keep up w the APT-C regimen! Which is a good problem to have— no complaining, just need it tamed down a little. By calc, APT-Zero/Lean Dosing should be the way to go after a tank matures.

    Amazing results right away

    This product is a dream. I’ve went through numerous liquid ferts, only to gain algae problems after use. Some actually contained trace amounts of liquid carbon that ended up throwing the balance of my tank off and cause algae to become abundant. Of course it is imperative to know what your tank needs; my tank is cryptocoryne dominant, but still needed some fertilizers to perk up the growth. I still dose following the instructions on the bottle, but only about 50-60% of the dosage for my tank ( 9.3 gallon tank, I dose 1 ML every other day ) and just based off the week of use, you can already see the results. The first picture is growth that was being hindered by algae and is small and crumpled. The second shows new growth, very strong and red coloration already. The third shows the lone bucephalandra I have with red and a much larger leaf (and still growing) than the others. This will definitely be my go to liquid fert for this tank, I finally found the perfect solution!

    Finally! A quality fert for fancy goldfish keepers!

    Among other tropical fish planted tanks, I also keep large imported fancy goldfish in 600g Pentair fiberglass tanks. Maintaining very low nitrate levels is an obsession with these delicate fish and I can FINALLY fertilize their plants without worry. I'm recommending it in all my fancy goldfish circles and those who have purchased are seeing an improvement in their plant health, growth, and water quality. Thank you SO much for this product!!
