Great high quality, effective, a little goes a long way
I use a little less than half recommended bottle dosage every day of all seachem ferts (rotate days between trace and flourish complete). Also use online co2 calculator and use just below dose of co2 tank from 5 am to 5pm. Then I air stone at night. Slightly underused recommended fish food once or twice a day. I take no days off. 2/3rd water change and vacuum every 10 days. Perfect numbers and very slow minimal acceptable algae growth on walls to be hardly visibly noticeable. I created my own HOB power filter and pre-filter using a number of materials from amazon sources. I only clean the sponges and not the physical media, squeeze them out in the throw out water that comes out during water change. Aquarium maintenance 101 from a newbie. Use as little substrate as possible to keep plants alive to more easily avoid snails. Clean literally everything before putting into aquarium, better for it to die before going in aquarium than to introduce snails. Scrape the walls of algae at each waterchange. If you get snails, take literally everything out but fish and inverts, and soak it in a low ratio bleach plus water bath for like 20 minutes, this is the only way to kill all pest snails literally. Drain the water to just enough for the fish and inverts to swim and live, then scrub the entire aquarium with a scraper and take out literally anything you can see. Scrape again 3 times. Wipe it all down and make sure all there is you can see is the fish and inverts and clear water. Then wipe again. Add plenty of cycling bacteria from multiple sources you can find on amazon including seachem. Refill the aquarium with the bleach soaked plants decorations subtrate and filter medias. MAKE SURE YOU SOAK IN PLENTY OF DECHLORINATOR AND WATER FOR 20 MINUTES first. None of your plants should die off completely but they will lose and have killed a good amount of their leaves and roots but they should survive and regrow if you fert and change new water and quick cycle with added bacteria I truly hope this helps. My first year with a fully stocked nano tank has been a lot of time reading and experimenting. The pest snail battle was epic but I've been free for 6 months completely. I win. Oh and didn't lose a fish or invert and plants are beyond original growth. This is with having done zero quarantining or adapting at any point. I also cycled from day one, no precycling. Use a 24 hour light with cycling phases and full K spectrum for plants. It is way easier and effective and worth the minor price increase over standard lights. And it is fun Also add Indian leaves and a UV filter Filter floss = crystal clear water. Chemical filtration is entirely unnecessary Have had no issues and made zero adjustments in six months everything has been clear and clean, green growth strong, living things have thrived.

I watched the leaves of my ficus bonsai go from yellow to green after I use this product. Since then, I’ve noticed many of my other bones, eyes being iron deficient. I had to calculate how much to use based on the known volume of one drop So I wouldn’t have to make large volumes. I only wish that the bottle came with a dropper or a lid that allows for single drops to be used easily.

It's a value for money product. My aquarium plants started smiling again.

En 100 litros, medio tapón cada 4-6 días para bajos requerimientos y va como un tiro. Esas hojas que empiezan a retorcerse quedan lisas en 24 horas.

Bottle tamper seal was deliberately pierced. Not sure if actually Seachem iron. Seems diluted to me. Some product was running in the bag.

The Nymphaea zenkeri is at its best colors and even brought out the reds on Hygrophila rosea australis and Rotala rotundifolia tips.
