Thrive S Shrimp Specific All in One Aquarium Fertilizer – 500ml Liquid Plant Food – Comprehensive nutrients – Aquarium Nutrition – Convenient to Use – Concentrated Aquarium Plant Fertilizer

Easy to dose and plants are thriving. No livestock death. I'm on my fourth bottle after several years of use.

Game changer plants love this stuff , no copper since that is very toxic to shrimps. Plants have been thriving .

Leaving original review to show I'm man enough to admit my original assumptions were wrong.But while I had issues early on, I believe I landed on where things went pear shaped so to speak. This does seem to be a solid product so much so, that I'm looking at the 4k ml bottle to toss on top of the two 500ml I got now into my 5k res.But pics show growth not otherwise achieved in what I think is two weeks without this doing something right.And yes the tannins / blackwater is on purpose, and I like it thst way if it keeps the right shading lolPoint being. Seems to be a pretty solid product for an invert tank w fish.---------I naturally have 0, 0, 0 for amonia, nitrites and nitrates.Yes my 30g systems that nice.Day 1, 6 squirts; 2 hrs later 0 nitratesDay 2, 6 squirts; 2 hrs later 0 nitratesDay 3, 18 squirts; 2 hrs later 0 nitratesGlad I paid $40 for 1,000ml of a urine colored liquid that by all accounts is nothing but dyed water!

The fertilizer is fantastic and has allowed me to grow luscious plants while keeping my shrimps safe and happy. The only downside of this bottle is that it's the SECOND bottle I've received where the squirt topper has come broken. It's simply too fragile and can't survive the shipping process. 5 star fertilizer, but loses a star for the weak squirt lid.

I was using API Leaf Zone and my plants were still showing major nutrient deficiencies, a few hours after adding this to the tank the plants already look much better! Shrimp are unbothered.

Despite the heavy bioload and regular root tab feedings in my 45 gallon tank the leaves of my Amazon swords were much too light and yellow in color and seemed to age VERY quickly and develop Black Beard algae at the edges and tips. Nitrates and nitrites were barely discernible in water tests so I figured the swords were missing their macronutrients and I had read good things about this fertilizer. Along with the rasboras, danios, and corydoras there are about a bazillion Amano and cherry shrimp so this formulation which is not quite as heavy in nitrates and does not need such frequent water changes seemed ideal. I use 8 pumps every other day and after a week my Amazons were much brighter green and now after more than a month of use everything is flourishing, the crypts have really gotten full and tall and the oldest outer Amazon sword leaves that are now fading and past their prime, are not attracting Black Beard algae. I do not use CO2. I do about a 20% water change every other week. I'm not focused enough to do carefully measured individual fertilizers so this all-in-one formulation was the perfect choice for my tank.

The media could not be loaded. This fertilizer is wonderful! My aquarium plants love it. I also have house plants growing and propagating on the top of my tank, so this fertilizer was just the extra boost I needed. Since it contains no copper, it is safe for my shrimp and snails too. I will continue to buy this fertilizer!

Expect nitrates to raise in your tank and monitor that if you have any livestock sensitive to high nitrates.I would suggest using with low tech tanks because I tried it with a tank that has CO2 injection and ended up with dust algae —that eventually went away (thanks to the nerite snails and light reduction).Love the easy pump mechanism
