do u have shrimps in tha tank too? how much do u add? or do u make a diluted solution? please help me in making a diluted solution as i have 2 30gal 1 15gal and 1 1.5gal. i only keep shrimps and moss and a few carpet plants coz i breed them so no fish.

I do have shrimp and they still reproduce. The shrimp will be coming out soon so I can use the tank to breed some Apistogramma cacatuoides though.



I dose about 2ml of Metricide 14 per day. I don't remember the concentration of Metricide 14 off hand and I'm on my way to work (not texting while driving though lol!), so I can't do the math at the moment.

Sorry, my bad. It's roughly 8-10 gallons.

I also put in 10mL in a 45g tank.

BUT Metricide 14 is WAY WAY WAY less concentrated than what you have. You have 25%.


Metricide 14 is only 2.6%.


So if you put in about 104 ml of the 25% stuff into 1,000mL of distilled water, you'd have about a 2.6% solution.

From there you could probably follow my dosing schedule (slowly increasing the dose to this level!).

Basically 2mL per 10g.

From what I read, excel is roughly 2.5% polycyclogluteracetal by weight.

You're actually making something closer to API's CO2 Booster which is a 1.6% solution of gluteraldehyde in water. You should be able to make a 1/15th dilution of your 25% solution (1 part of your solution to 14 parts water) and it ought to work just fine. Dosing according to their instructions is 1 mL per 40 liters daily. I've been using this product in conjunction with DIY CO2 and have seen a significant difference in the growth of my plants and things like pearling in the afternoon/evening. It hasn't bothered any of my shrimp.

Take care with the 25% solution. The 1.6% solution is nothing to laugh about, but it takes less than a mouthful of the stronger stuff to kill a child. (LD50 for gluteraldehyde is only 134 mg/kg, so roughly 10mL of the 25% solution would be enough to kill 50% of 20kg children who swallowed it.) It's also fairly nasty stuff on your skin and inhaled. Like many things, it's perfectly safe if used and stored properly, but it's fairly awful if not.



More or less, excel contains polycyclogluteracetal, basically polymerized gluteraldehyde. I imagine it's a stability issue, both in the tank and in the bottle. In any case, if you spray it onto the plants it can cause problems, and it's reasonably toxic stuff.
Well that means 1ml of glut (25%) to 14ml water, that makes 15ml solution which will work for 15days, as mine is 90l so for me will work for 7 days, correct? but what if i dose 0.25ml of glut(25%) directly into the tank??

Can you show me how did u calculate that? im very bad at math. i just added a drop in my 9l nano tank to see what happens, it just has a beta, hairgrass and some java, and toooooo much algae as i dont change water, just topup but today i changed before putting glut, changed 70%.

Sure. And hopefully someone will correct me if something is wrong. I'm a theology specialist, not math :icon_roll


To find out how to make a (roughly) 2.6% solution, so that you can dose the same I dose (2ml per 10g), here is how I got it.


Starting with a 25% solution, and using a super-easy amount of water to mix it in (1,000mL) for easy math. Here's how it works.



"X" is the amount of your glut bottle to add......... (0.25) represents your glut's concentration.......... (0.026 represents the final 2.6% solution after you mix it up).

Thus you get this equation, and solve for X.

0.25x / 1000mL = 0.026

Or restated,

X= (0.026*1000mL)/0.25

Which equals 104mL. Thus you add the 104 mL of your 25% glut to 1,000mL of distilled water, and you have a crude 2.6% solution, which will replicate the Metricide 14.



All that being said, I'm sure I way overcomplicated the math the same way Don Quixote overcomplicated fighting a windmill lol!

add 104 ml of 25% glut and than fill it with distill water to 1000 ml so 896ml of distill water and 104 ml of 25% glut.

Point well taken.

The final solution needs to end at 1,000mL. So use 896 mL of distilled water, and there is your final 2.6% solution. Don't fret a few mL of distilled water, your equipment may just be easier to measure out a nice rounded 900.

Starting with 1,000mL instead of 896mL would not have hurt anything except to make a slightly weaker solution.

well so if i want to make API CO2 booster, that holds 1.6% glut then would it be like this:
1000ml*0.016/0.25 = 64

so 64ml glut. 25% in 1000ml water. is that correct?

I don't dilute the Metricide 14, it seemed like a waste of time to me to add water to the stuff I'm adding to water... Anyway, I've been dosing up to 15 ml a day into my 29 gallon to try and knock down some bba. The only thing I've noticed is some of the snails dying off and that's not necessarily a bad thing, as long as they don't all die at once. There are no shrimp in this tank yet, but it's full of java moss and several vals as well. I've seen no issues with either of mine at this dosage, just the bba slowy melting away.

hey, in what water should i dilute it? normal tapwater or a good filtered water? i have a water purifier which has RO, UV, Carbon and tds controler all in 1 filter, i use it for my marine and drinking water.

k then, just got a good lab grade 1000ml bottle, gona make my own diluted glut. from 25% to 1.6%. (800ml (distilled water) x 0.016/0.25 = 51ml(25%glut.)) so total ill make 850ml. Any last final suggestions or thoughts? or should i just go ahead.
