Metricide 14 is 2.5% gluteraldehyde. Excel is an unknown % of polycycloglutaracetal. Similar compounds with similar results. Metricide is supposedly twice the strength of Excel, but I have not seen any strong evidence to support that claim.

Well I guess I'm under dosing then, judging by how much glut everyone is using! I dose 8ml for 30 gal tank, still see some algae, may be I should increase to 10ml?

~25 mL Metricide / day - 65g.
If your fish aren't doing well, it's not due to gluteraldehyde. New fish do fine when I've added them at various stages of my increasing glut dosing. Neons, cories specifically (increasing schools and shoals). The reason I slowly up my dosing is due to escalated plant growth, nothing more. I've upped dosing to around 40mL per day with no ill affect on any of my fish, snails, or shrimp. I upped it about 3mL per week to get where I'm at. Though I don't dose all 40mL at once. It's split to 20mL every 12 hours, and I do six 3-4mL injections all over the tank (each corner, and the front and back middle of the tank).

Oh boy wish I knew what to do. On this site everyone seems to use high glut with no issues. On the planted tank I have a thread and everyone is saying that the 15ml a day in my 60g is WAY too much and toxic. (Including people who are known as the experts on that site such as Hoppy).
It's so confusing and the problem is that my fish keep dying. I'm freaking out as I've already lost 3 in 3 weeks so something is wrong and I just don't know what or what to do!
Yah tpt has entirely different views on glut, those guys under dose excel actually. I can only speak for my own experience with metricide. Just actually recieved my my 2nd gallon a few days ago. I've been dosing on the high side at .5ml/gal for months and months. My rams and shrimps are all still kicking. I'm guessing if your fish are dropping like Flys there is something else going on in the tank..

Out of interest did they say why or have any examples? Curious on what they were seeing.
No, they just said that metricide is highly toxic and felt that glut should not ever be used at more than double the dose on the Excel bottle as it's toxic to the fish.
It's a tough call for me as I know lots of people on here use high glut and I have to say since I've started using it my algae problem is MUCH better and my plants are growing like crazy which is great part, but the sickness and deaths also coincide with the glut increase. Might be a coincidence as nothing else has changed. I joined this thread as it was a survey on glut dosing but I have another thread on here asking for input on why my fish keep getting sick/dying and I've had responses from others but not really got any other ideas of what it could be.
Strange. Although all my fish I've had for some time and the fry are I guess used to my water conditions. Which thread is yours out of interest?
I don't know how to post the link from my phone. It's in general discussion and called why are my fish getting sick. I will post the link when back at my computer tho.
