CrystalClear Thrive Pond Plant Food, Fish Safe Fertilizer, 200 Tablets

After years of struggling to get my pond plants to bloom properly, I finally found something that actually works. My two water lilies were producing plenty of leaves but barely any flowers, and a friend suggested I try a dedicated aquatic fertilizer instead of the generic stuff I'd been using. Picked up these Thrive tablets and honestly didn't expect much of a difference so quickly. Pushing the tablets into the soil is about as simple as it gets. No mixing, no measuring liquids, no worrying about clouds of fertilizer drifting through the water. Within about three weeks of the first application my lilies started pushing out multiple blooms at once, which hadn't happened in the two summers I'd had them. The lotus I added this year is also coming along beautifully, roots spreading out and new pads unfurling every few days. My koi and goldfish have shown zero signs of stress, which was honestly my biggest concern going in. The water stays clear and the fish behave completely normally, so whatever they put in these tablets seems genuinely safe for the whole pond ecosystem. The only tiny gripe is that 200 tablets sounds like a lot until you realize a larger lotus needs four per feeding, so heavy users might burn through a container faster than expected. Still, the results speak for themselves and I'll absolutely be buying again next season.

our pond plants were suffering. They weren't growing very well and weren't flowering. Then we acquired a lower degree of stupidity! We bought this fertilizer and the plants are VERY happy now. great product, easy to use. I just have to get IN the pond. But, frankly, there's no way around that :)

Very easy to use. I’ve used these tablets twice now and do believe that it has helped the growth and blooming of the pond plants in our pond.

I fed my water lillys this product and about a week later I started to see blooms. You just push this into the soil and that's it. My Lilly's are growing like weeds!!

very effective works well and the plants look great. no smell and fish safe

This really works! I bought a beautiful water lily and it’s bloomed 7 times because I’m using this monthly.

Very disappointed! I received the fertilizer "tablets", BUT the bottle was more than half way stuffed with cotton and the rest was powder. There were ZERO TABLETS in the bottle!!!!

Purchased March 18, 2026 and I have been using it on my Nymphaea odorata, which is growing and looking great. When I went to use it on May 1, 2026, I found that all the tablets have turned into powder. I would like to know how much product is in each tablets (is it about 1 teaspoon?) so I can estimate and continue to use it and not lose my $25.00. Update: Google suggested putting 1/2 to 1 tsp in coffee filter paper and twisting the top to make a quasi tablet and placing it in the soil. I tried that and it worked!
