Frequently asked questions

Is this safe for fish, shrimp and snails?

Yes when dosed as directed. It supplies plant nutrients only — no copper-based algaecides — so it is safe in planted community tanks, including with shrimp.

How long will one bottle last?

At 1 tsp per quart, the 8 oz bottle makes about 48 watering cans of feed. For a typical shelf of 10–15 plants fed every 1–2 weeks in season, that's several months of feeding — and the 32 oz bottle four times that.

Will it cause algae?

Algae come from imbalance: too much light or nutrients relative to plant mass. Dose at the labeled rate, keep lighting to eight hours or so, and healthy plants will outcompete algae.

How do I dose it?

Follow the labeled rate for your tank or pond volume, or push the diluted feed into the soil of potted plants so the roots take it up directly.

Which plants can I use it on?

Anubias, java fern, amazon sword, cryptocoryne and vallisneria, and other rooted aquatic and bog plants.

When will I see results?

New leaves come in greener and larger within two to three weeks; flowering plants set more buds over the following month.
