Very high quality planted aquarium micro fertilizer.
This was a game changer for my dutch aquascape that was suffering tremendously. This does not come with any instructions because its a raw compound dry micro. I used GLA's fertilizer calculator and was dosing in a matter of minutes. After 2 weeks of dosing I could see massive improvements in just about every plant. I have over 30 types of plants in my 180g tank. This micro boosted my plants into happiness. My monte carlo carpet responded so well it started to consumer my hardscape. I was worried about the copper in the micros but so far all my shrimp and snails are ok. When I dose they even go as far as to try to eat it before it melts. It melts almost instantly. I think this jar will last me almost a year. I have a big tank with weekly water changes so its very demanding. This is a very cost effective way to feed your tank.

Love these micro fertilizers by GLA.
I switched from the EDTA version and wow what a difference. I was an amateur to basic water parameters but now that I spent all of 10 minutes learning I now have the best fitting micros my tank has ever had. Cost effective, and I feel this one single jar will last me a year easily.

I would give this 10 stars!
This new micro GLA has works better for my waters chemistry. EDTA strongly holds iron in solution up to pH 6.0, but by pH 6.5, almost one-half the iron is precipitated, and by pH 7.0, almost none of the iron is available to plants. DTPA is an excellent iron source up to media pH 7.0; however, 60 percent of the iron is precipitated and unavailable by pH 8.0. You get the best of both in one micro!

Top shelf micro
This micro is really really good. I finally have deep rich greens that stay vs fade away at the end of the week. My reds are peaking with luminous red and it stays vs fading away at the end of the week. This micro is extra complete like nobody else is offering. Containing both EDTA and DTPA ensures long lasting nutrients in the my tank and my plants are paying for themselves with all the clippings Ive sold lol.
