substate fertilizer
very interesting method to deliver substrate fertilizer.

Came free with co2 system
I received these free with my co2 system. I've only had them in my tank for a few days, so I can't give any real feedback on the efficacy. I will give feedback that these should have a desiccant packet or something to reduce moisture. A lot of the ones in the packet I received had seemingly melted together. This could be from heat, moisture, or both. I have other gel capsules so I can still use the fertilizer.

2 years now on only tablets!
I try them all, Niloc type,Seachem type and Aquario type. These GLA capsule work the best, and you get so many in one pack for a good price. I now go on 2 years maybe slightly more with only these tablets. I use 2 packs in my 90g tank. I refresh every 7-12 months depending on how plants are going. I notice when I do more frequent water changes during the year I need more. But when I stay on EI schedule with 50% water change everything is ok. I like not dosing and this has helped so much.

These are amazing!
After 2 years of using traditional aquarium fertilizer I skipped year 3 and chose to use 2 packs of these. I started with 80 caps and I still have 20 left. My red plants are more red and general growth was exactly the same when I used liquid fertilizer. What I like about this system is you install once every 6-12 months. I chose 6 just to play it safe and life has been great. I no longer worry about my plants when Im on vacation. I just add more prior to when I leave. I dont think I will be switching back to liquid fertilizer any time soon:)

GLA SUBSTRATE FERTILIZER CAPSULES - AQUARIUM ROOT TABS
Just put them in my substrate. Have to wait for results but looks good and never been disappointed with GLA before.
-
Nutrient rich fertilizer.
I keep a very demanding tank and recently switched jobs that keeps me away. I panicked, had lots of experience with other brads so my panic was elevated. I tried GLA for 4 months with no issue on plant growth. No stunting and no excessive nutrients in the water column. Im on my second pack so Im not sure how long they will last me but so far its been very economical vs liquid dosing. This is working really well.
-
Amazing growth from these.
I’ve used a lot of fertilizer tablets over the years and I feel this pack shines the best. My plants just seem richer in color. I’d say growth is on par but the general health and color just seem much better. I use these because I travel and do not dose my tanks much so these have been amazing.

Shrimp safe fertilizer tablets!
Finally a tablet I can fertilize my tank and not worry about my Taiwan Bee’s! Plants are happy

Fabulous substrate fertilizer system from GLA
Only my second batch after 6 months. I wanted to see how the first bag went and I was blown away. Im now on my second bag. I used Niloc tabs before but I did not get much response to growth with my plants. With these you see it very quickly and it last quite a while.

Worth their weight in gold!
My first bag of these were free with a prior purchase last year. I ran out last week and was happy to receive these so quickly. I dont have much time for daily dosing so most all my plants are fed with these now. One thing I noticed right away was the lack of alage in my tank since I started using these. I emailed GLA and they said the capsules did not remove the algae that perhaps the excelled plant growth helped stabilize my tank with the absence of water column dosing. I ordered 10 bags and I feel that will last me for years of dosing. I dont think I will ever dose the column ever again. These are the bees knees.

Ive tried every substrate fertilizer on the market. None work like these.
Used them all, even DIY versions. Everything from easy-green tablets to niloc tablets and these puppies are like steroids for plants. I use mostly root tabs for my fertilizing because I travel a lot. I have been use to what all the competing tablets achieve upon my return home. Honestly, it makes for a great quality control test environment. Considering I have used all of them. Well, I came home from business and my plants were easily overgrowing one another. Im not sure of its the time release effect, or the nutrients inside. Either way the plants respond like no other.
-
Good results from these fertilizer tablets.
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.
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.
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.
-
My plants love it!
Couldn't be happier! Thank you!
-
Lovely addition to my PPS Pro dosing kit.
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
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.
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.
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!
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.
