Potassium in GLA Ultimate GH Booster Compared to Seachem Equilibrium

Hi guys,

Just ordered 2lbs of Ultimate GH Booster from GLA but I can't find out if it has enough K in it. I'm trying to move away from Seachem since most of their stuff is a rip-off IMO. Quality is good but price is too high.

I read that it raises the GH by the same amount as Equilibrium, but what about K? Does it have a similar amount to Equilibrium or will I have to dose K apart?

Also what about micros? Does it have a similar amount of Fe and Mn compared to Equilibrium?

Hi The Coffee,

LOL, I thought you were in Seattle. You would need to check with GLA but it likely the same formula as AquariumFertilizer.com which it Tom Barr's formula. The formula is:

By Volume:
1 Part K2SO4 (Potassium Sulfate)
2 Parts CaSO4 (Calcium Sulfate)
1 Part MgSO4 (Magnesium Sufate)

If it is based upon Tom Barr's formula it should have an equivalent amount if K as Equilibrium; no it would not contain any of the micro-nutrients that Equilibrium contains.

Isn't the Barr gh booster 3:3:1 caso4:k2so4:mgso4?

That was my understanding also.
Which puts the ratio of the ions in water @ 1.00 : 8.96 : 13.65 : 14.08 Mg:Ca:K:S

Seems a little skewed, but I don't have much idea about ion balance. Time for some more research.

Feel free to edit.

Hi nilocg,

When Tom Barr spoke at GSAS in the fall of 2010 he stated the formula as:
"it about 1/2 Potassium Sulfate (K2SO4); 1/4 Gypsum (CaSO4); and 1/4 Epsom Salts (MGSO4)". I think the difference in the numbers is due to how we measure the "parts"...whether by volume or by weight in grams......I was talking volume not grams. Most of the time I see the Barr GH Booster formula expressed in grams.

Ok got ya, ya ive seen 3:3:1 by weight. And honestly its really not going to matter much. Both are probably going to get you to the same place.
