Product Description

2Hr Aquarist APTF FixLite 100ml

The gentler way to treat algae.
Specially designed for Mosses, Liverworts (Riccardia, Riccia etc.) Vallisneria (Tape Grass) and more delicate plants. Biodegrades completely.

Spot-dose up to 1ml per 10L every 24 hours.

Top algae magnet

Organic waste and decaying matter are top algae triggers.

Regularly change water the 2Hr Way and remove old/ decaying leaves.

Stem plants require replanting of the healthy tops after trimming once or twice. Old deteriorating stems invite algae to bloom.

no copper

The problem is that copper, like other heavy metals, accumulate over time and do long term damage to the tank’s ecosystem.

Both APT Fix and APT FIXLITE use active compounds that biodegrade naturally over 12- 24hours, with no nasty residues.

magic 70

The best natural defence against algae is a healthy dominant plant mass. 70% of a tank’s substrate should be planted.

Tanks with large exposed, un-planted areas are far more susceptible to algae, in the same way that fertile open fields invite weeds to grow.


Yes, but this approach is alot less effective than spot-dosing or drain-dosing. We recommend spot-doing with the included pipette.CAN I TREAT CYANOBACTERIA AND BGA (BLUE-GREEN ALGAE)?–

Yes. Both APT FIX and APT FIXLITE are effective against cyanobacteria / BGA.SHOULD I GO FOR APT FIX OR APT FIX LITE?–

Go for APT FIXLITE if you have algae on Mosses, Liverworts (Riccardia, Riccia etc.) Vallisneria (Tape Grass) and more delicate plants (usually hybrids or rare species).It is normal for algae to develop resistance over time. Nature is amazingly resilient, and they adapt! If APT FIXLITE does not work, try APT FIX. And vice versa.


APT FIXLITE contains a proprietary mix of carboxylic acids. These carboxylic acids selectively inhibit various processes in algae cells, while leaving higher order plants undisturbed due to their thicker cuticle layer. The active components react quickly with algae, but is quickly digested by natural microbes, with no accumulation of residues in the aquarium.HOW OFTEN CAN I DOSE?–

Both APT FIX and APT FIXLITE biodegrade naturally over 12- 24 hours. So you can repeat the recommended dosage very 24 hours.

  • Quick service, fantastic plants

    I have ordered from Aquarium Gardens for the first time after seeing them on social media. Well what can I say except WOW, the plants were a really good price, they arrived on time actually quicker than I expected! They arrived in absolutely fantastic condition as if I had picked them out myself, well packaged. The plants themselves were bigger than what I expected to get so definitely value for money and the root systems were well established, can't wait to see them get bigger in my aquariums. Will definitely buy from this company again.
