Great product, effective, 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 bacteriaI 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 funAlso add Indian leaves and a UV filterFilter floss = crystal clear water. Chemical filtration is entirely unnecessaryHave had no issues and made zero adjustments in six months everything has been clear and clean, green growth strong, living things have thrived.Electric heater w built in temperature control at 82 degrees for tropical fish and plants

Only use when necessary
This fertilizer works great and I believe most of the sources of negative reviews are people misunderstanding the use of this product. While it’s an all-purpose fertilizer, it shouldn’t be used every week like some people say. It should be saved until you notice your plants have a nutrient deficiency (see attached photo). Poor lighting and poor water quality can seem like a nutrient deficiency so once those are dialed in, you shouldn’t change them dramatically. The reason I stress why you shouldn’t use this weekly is because adding it will alter your water chemistry. It will raise TDS (total dissolved solids) which some fish are sensitive to. In addition, it’s impossible to know the nutrient levels in your tank without specific testing strips/equipment. An influx of any nutrient can become a problem for fish/algae and especially invertebrates. I’m not saying you should go out and buy brand new testing kits, but instead only use this product when needed, not as a regular routine. That will keep your tank much healthier and prevent excessive nutrients which can cause algae outbreaks and imbalances in water chemistry. As far as this specific fertilizer goes, it works great. My only complaint is how concentrated this is since dosing a 10 gallon tank needs 1/8 teaspoon which is a tiny amount. At least it will last until it expires.Update: This fertilizer works great. My plants looks very healthy and my fish, snails, and shrimp are doing fine. I highly recommend this as opposed to expensive alternatives

Seller is prompt. Amazing product. Has all the micro elements which aquatic plants need. In addition to that it consists of trace elements also. No harm to fish if not overdosed(please see the dosage direction) .

Good for planted tanks

Mis peces suelen picotear algunas plantas, asà que con esto están mas sanas y crecen mas rápido. Es caro pero merece la pena si tu acuario plantado no tiene un abono en su base.

Purchased this as I thought I would try again to keep my plants in Aquarium alive after failing before. They are doing well since using this. I thought for the price it was good value. It will last ages.
