Horrible awful tabs

Turned my water murky and gross like creek water. Did nothing but cause havoc in my tank. Hate them!!!!

Tank Flourished

We are new to having live plants. At first I wasn’t sure about these because the water became cloudy the first day. By the next day the plants already looked healthier and the water had cleared. Don’t do a water change immediately after putting these in and let them start to do their job (also make sure the roots are buried). 2 weeks later and my plants are healthy, my frogbit has doubled, and my octopus plant is twice the length. Highly recommend!

Cloudy mess

These tabs left a cloudy mess in my tank. Ended up having to buy seachem purigen and do water changes just to get rid of the cloudy mess. Will never use root tabs again

So Far, So Good

I didn't have a problem with them dissolving, put them in the substrate with a pair of tongs near a couple of plants that are slow growing to see if they help. So far (2 weeks in) the plants have nice color and growth.

Don’t use!

Worst product ever! I wanted to help my plants flourish. Immediately regretted it and had to do a completely water change. Made water cloudy and murky and couldn’t see anything. It’s still cloudy, I’m just hoping it clears it up. Don’t waste your money.

must buy product

The tab belts do start dissolving fast but not to the point where you can’t get them in the Gravel. Also it might make your tank a little cloudy it will clear up within 1-3 days depending on how many tabs you put in. I used the api acu clear to help with my tank and my plants have never loots better

Don't waste money

These things are horrible they were like powder in the package instead of pellet. Immediately dissolved before I can even get it down into the roots of the gravel. Messed up the water. If you're going to use root tabs buy Fluval
