So far so good. My anubias are sprout noticeably faster. I'd consider it a success if the new leaves don't get covered in BBA.

I'm dissolving the powder first because the guppies will try to eat it.

I dosed excel to fight back the BBA after a water change. It wrecked the moss and singed the anubis where I was spot treating. Some plants are way more sensitive to excel than others.

If you have to fight bba, the organic carbons you added is doing more harm than good. The high tech folks believe organic carbons from fish waste trigger algae and thereby need frequent WC, and you just add more organic carbons.

I do weekly water changes. It does help with other types of algae but I think the thinkings behind BBA are anecdotal. I'm skeptical. I have tanks where I don't change water at all and have zero BBA.

I've always have had BBA in this 75G tank even when I ran CO2. They don't go away. I periodically hurt them with excel.

Update on this with daily 1/4 tsp of dry carbon in a 75Gallon tank. In addition to regular water column ferts dosing.

May 8, 2018


The crypts were sad looking for months, not doing much.

July 4, 2018

It's taken 2 months but looking better. The crypts are on a layer of dirt since the beginning.

Update on growth



I dose 1/4 tsp in a 75G for 4 days out of the week. Adding too much does seem to stimulate the BBA a bit but all of their growth is on the hardscape. The plants are heathy enough to ward them off.

I think I'll add fructose into the mix. Seems like any simple 6 carbon molecule will work. I think fructose isn't used in commercial products (liquid form) is because of shelf life but in powder form, it'll keep.

Is it too early to reach a conclusion about using this alternate form of carbon?

I added fructose (monosaccharide) into the mix. It is the cheapest carbon source, $2.50/pound. If that's all you'll add, go for that. I'm still doing multiple carbon compounds.

I think it is a good alternative but doesn't look like it works for java ferns. They develop black spots necrosis on older leaves but it still grow new leaves.

I'll go ahead and only use fructose and I recently added a buce & h. pinnatifida.

I'm switch back to the multiple mix of carbon. After a week of only fructose, I'm noticing more BBA growing on the leaves that receive the most light. That tells me the plants are not doing so good.
