    Good results from these fertilizer tablets.

    Posted by Lee Parsons on 3rd Sep 2021

    So far the plants are doing very well. Growth is steady and no sign of deficiency. I also dose PPS-Pro so Im sure this factors in. All in all the combination of the two is a great bargain.

    My favorite aquarium root tab fertilizer.

    Posted by Mara Strouse on 27th Aug 2021

    I like the fact how many you get in the bag. This packet last me months and my plants are totally rockin. Most of my plants are stem plants followed by crypts ,Monte Carlo and a mix of mini hairgrass. My sword plants are happy, new leaves on the regular. These are great because I don’t have much time to dose everyday or every week for that matter. I use to dose my tank religiously, but not any more. I’m lucky to add micros once a month now.

    I love this aquarium substrate fertilizer tablet.

    Posted by Justin Holt on 31st Jul 2021

    Very economical and are lasting a long time. I originally ordered these because I was leaving on business for a month. I was skeptical at first, Im not a skeptic any longer. When I returned home it was if my tank did not skip a beat besides the stupid amount of trimming I needed to do. The tank had zero algae and my plants looked better than when I was tending to them weekly. I now use these tablets in all my scapes.

    Lovely addition to my PPS Pro dosing kit.

    Posted by Alec Wrigley on 9th May 2021

    A few months ago I implemented these into a tank using PPS-Pro and the results have been terrific. I stopped dosing mid week just to see if I could get away with it. No issues with my inverts at all and my plants are totally happy. Really digging the 40 count pack!

    Perfect balance of nutrients

    Posted by Matthew DeWitt on 3rd Apr 2021

    GLA substrate fertilizer capsules have the perfect balance of nutrients for the planted aquarium. There is no ammonia spikes, no contaminants, and no bs. I love these caps, and my tank is thriving thanks to them.

    Tank is stable and happy.

    Posted by Shane Raston on 21st Mar 2021

    Really enjoying this substrate fertilizer from GLA. I use these in my home tank and office tank and dose PPS-Pro on the side about 50% less than you normally would. Plant growth is great no stunting. You do need tweezers to plant these so make sure you use that or an old set of chopsticks, worked for me.

    Very happy plants.

    Posted by Ramon Suerez on 5th Mar 2021

    I switched to GLA capsules from Tropica a few months ago. The vigor I see from my plants now is night and day. You need tweezers to insert into the substrate, I use an old chopstick set. My stem plants especially the rotala species are looking much larger in terms of the leaves, the stem girth is noticeably larger and more robust. Not so soft anymore. My only wish is for them to create a solution for feeding rhizome plants or epiphytes that do not root into substrate. I dont prefer to dose my water column any more and is why i use fert tablets only. I have used every damn tablet on the market and decided to give these a try. These are the only ones worth leaving a review about because Im finally happy.:)

    Where have you been all my life!

    Posted by John Hunter on 9th Feb 2021

    These babies are freaking awesome. You get a pack of 40 which to me is terrific. You will need a set of tweezers to push them into the soil but once they are in your plants are going to thank you with lush growth. My main reason for leaving this review was because my red plants have gone to level 1000 red. I wish I could post pictures here, if you could see you would buy these right now. I was using niloc fert caps but realized they contained copper and were just some dirt and plantex micros all mixed up. At the time I did not know any better, what a horrible mistake that was. This about it, a tablet with some dirt and micros, wtf? Dont be fooled by the kool Aid folks. GLA fert tabs are the cats pajamas.

    Much better than what I expected

    Posted by Seth Berchfield on 25th Jan 2021

    GLA sent me these prior to the launch and I have been using them for 5 months now. I like these so much Im going to stop dosing my liquid solutions completely once the tanks are mature enough. For new plants liquid or dry salts would be in order. You cant use these with epiphytes but they are great for anything growing in the substrate. One thing in particular I noticed with these is how it made my carpet plants more lush and deeper greens. It made me wonder more about what my plants were missing from the substrate. From what I recall all plants take up nutrients through the water column, and I dose my water column EI. I can only guess plants prefer nutrients through the roots and maybe this is why ADA substrate is so good. You will not regret starting to use GLA fertilizer capsules. As I type this they are giving these away for Free if you meet the required dollar amount.

    Next level substrate fertilization

    Posted by Clive H. on 18th Jan 2021

    I was lucky enough to try these way before they came out with a few others to trial in a couple of aquascapes prior to AGA this year. These tablets are the real deal. These contain no copper nor are they some mystery mud mix. These things kept out plants in stellar condition and they do not create a mess after they are old. I use this along side a modified version of PPS only because the tank is very fast growing so we want quick nutrients after trimming. These will get your plants looking like I could never get them to prior. Ive only had them for 3 months and our dosing is definitely considerably less. We no longer have any measurable amounts of No3 in the tank or Po4. Prior we had about 10ppm of No3 and 2ppm Po4. The plants look super healthy, and to the best I can describe it is the plant leaves look very waxy. As if they are grown emerged form. Thats a terrible description but I cant say it any other way. These fertilizer tablets I believe are the next level in substrate fertilization. This shop keeps my bank account empty on the regular.
