Yep this one is for 200mg.

1 tablet per 10 US gallons for 5 days.
So...I have 5 US gallons. If yours are 400mg, then I need 1/4 of a tablet for 5 days. So 1.5 tablets should do me then?
I read in the article you gave me gf about half dosing if its for bga, but there seems to be a bit of a debate about this as to whether its enough. Problem is if you dont get it right first time the bga will become resistant. I have no fish to worry about at least.

Been trying to read more about bga.
So far I've come up with:
* tends to start from the substrate
* stagnant water doesnt help
* like any other algae (altho bga isnt algae) its about trying to get a balance and getting your plants to outgrow the bga
* I've read that 3 day blackouts work...and I am proof of that...altho I'm getting traces returning, which is proof that yes, blackouts work, but in the long run you have to fix the source of the problem
* I've read that 3 day blackouts don't work and make it worse...I'm proof of that too! I'm still convinced the fish must have eaten it in the 20 gallon.
* antibiotics are a risk, because if you don't do it right it will come back and will build up a resistance to the antibiotics. Also I get the impression that you still need to solve the root of the problem, cos it will come back.
I have some things I'm going to do and monitor to see if things improve.
20 gallon
I'm going to keep vallis trimmed as it forms an area of still water where the bga did grow before. I think I shall probably gradually remove the vallis and replace with another fast growing plant.
I already clean the glass between glass and sand, but I'm going to try and do this more regularly than once a week to keep bga at bay.
CO2 isn't brilliant at mo as I'm using 1 nutrafin unit, but changing every 2-3 days. But fingers crossed I'll have the pressurised running by the end of the week.
5 gallon
Give the maracyn a go. Keep on top of changing CO2 to keep above 30ppm. I've also cut the light to 4 on, 4 off and 4on temporarily. The bga grows at an incredible rate in this tank. The temperature is at 28 degrees (purely from heat from tube) and I cant get it lower. And theres 4.8 wpg, but I cant find any references to bga flourishing more in high light and high heat.
Thats it for now. thanks for reading.
