GLA had me overdosing csm+b?

I don't think you can over dose ferts, that is the whole idea of the Estimated Index method actually. It's substantial, like 15 times higher. But it could be a different mix or something. I have the same bottles and dose a different concentration.

40g/500ml= .08 g/ml at 1ml per 10g that's .08 grams per 10 gallon.

28.6g/500ml= .0572g/ml at 0.1ml per gallon thats .00572 grams per 10 gallon.

.08/.00572 = 13.99! They are asking me to dose 1/14 or what I was! Am I crazy here?

Bump:

This isn't following EI.

I never did have great success with my tank before, is it possible that GLA had me seriously overdosing?

Just to clarify. My statement on the EI was referencing your lack of success due to overdosing. :wink2:

I believe @Edward , they guy behind pps-p, "officially" lowered the dosage for micros about a year ago.

GLA's new recipe probably reflects the change. It's mentioned in their FAQs somewhere, one of the how-to links under ferts iinm

I have no experience in planted aquariums yet, but I've grown a lot of plants above the water. It's absolutely possible to overdose ferts. Everything has a toxicity point, and if you dose enough to reach that point, you will have problems. EI works because it uses 50% weekly water changes to ensure that the concentration of ferts in the water column can never go above a certain point. If you were to dose EI without those water changes, or dose dramatically higher than EI levels, you could easily cause problems.

This is all hypothetical, though, since i have no idea how the dosage the OP has been using actually compares to EI, nor do I know what sort of water changes were being done. And if I knew those things, I still wouldn't be helpful, since I don't know the toxicity levels for any of these things. I just wanted to clarify that overdosing ferts is possible if you try hard enough.

Slight tweaks I could understand but 14x different is insane to me. I'll let you guys know what they say.

It went from daily .1 Fe to .01

If you ask me he got caught up in the "micro-tox" craze happening at the time. (which certainly has some merit but that's another story)

It was a knee jerk reaction to forum discussions, rather than a result of further research or trials.

It was surprising to me how quickly he jumped on board instead of defending the system with confidence. It makes me wonder how much actual knowledge was applied to begin with.

Just my humble opinion, of course.

I had purchased a PPS-Pro pack from years ago. At that time they said to use 40g per 500ml at 1ml per 10 gallons. I looked on there site to check everything and they have an update saying to dose 28.6g per 500ml at .1ml per 10 gallons.

I haven't crunched the numbers but thats a HUGE difference. I emailed them asking if they changed their recipe for CSM+B or anything. I never did have great success with my tank before, is it possible that GLA had me seriously overdosing?

Straight from their site

Plantex CSM+B – 28.6 grams (Trace Elements (TE) recipe updated 4/11/2016, previous recommendation was 40 grams)

Bottle #2 Micros: daily dose of 0.1 mL or 2 drops per 10 gallons or 40 litres of aquarium water. Dose daily, prior to your aquarium lights turning on. (updated 4/11/2016, previous dosing recommendation was 1 mL per 10 gallons)

Our PPS-Pro Fertilizer Pack ? Just Mix & Dose ? Planted Tank Blog

No need to wait for them as they say right there in red font that they changed the formula in April 2016 from 40grams to 28.6 grams and dosing changed from 1 ml /10 gallons to .1ml/10 gallons.

I've never used this method but doesnt it rely on the end user to test and ensure the dosage works well in your setup?

PPS-Pro like EI doesn't demand checking parameters constantly. I did watch nitrates and they would creep up high enough I wasn't comfortable and would do a water change. They didn't change the dosing amount for the macros though.

Maybe I'll just be a sheep and go the EI route. I just liked avoiding the water changed lol

That is correct. Edward created the PPS Pro System (PPS) and is with Aquatic Plant Central (APC). Green Leaf Aquariums simply sells the fertilizers. Once the formula changed, they quickly updated the info on their web-site. As an added point, the changes to PPS Pro also included a recommended weekly 50% water change.

I am using the new method with much success. The old way worked too. FWIW, if someone could change the title of this thread, they should, as it's unfair to GLA.

You hit the nail with overdosing! Absolutely correct 1+,cheers

I can't find where to change the thread name. If any moderator wants to change it I certainly don't care.
