Algae nutrient supplement
This stuff is really good, not only for chaeto, but for fertilizing all macroalgae.

Excellent tool for a refugium or algae reactor.
I put this on an auto doser for daily dispensing. I dose 2ml per day. Since it's addition to my reef aquarium it has certainly boosted the growth of the chaeto in my algae reactor and in turn lowered my nutrient levels.

Answered prayer !
SCRUBBER STEROIDS IN A BOTTLE !! Used Santa Monica algae scrubbers for 3+ yrs and never before has there been this amount of growth. Never. I am using (just) 3ml daily (165-gal systm) into the sump where the scrubbers are. Algae on the gravel-bed in the tank has abated 85/95% in 3 weeks. PH is 8.5 MAGIC POTION !! Get it, friends !! I have goniopora, elegance, frogspawn etc. Everybody happy, happy, happy.

i'm no expert
we first started this with some spaghetti algae (don't recall the scientific name chaeto something) it died, then we went with lettuce algae (again don't recall the scientific name) and it has stayed bright green and is thriving, so i blame our set up / lighting over this not working. but again i am no expert so this may not be doing anything then again it may be what is allowing the lettuce to be able to forgive us our newbie mistakes.

must have for marcoalgae
very significant result for my tank. coralline, chaeto, caulerpa, all the marcos grow like crazy just after three days dosing. skimmer also collect more waste (mainly microalgaes). If you have high nitrate/phos but all the algaes do not grow, you need this.

Works, no issues.
Dosing very lightly as needed, 0.1 ml per 16 gal. Had no problems with invertebrates. Chaeto grew faster, denser, and darker. Keeps Caulerpa prolifera from melting. I had a bunch of Caulerpa grow, and only had one blade melt, before Chaeto Gro it was a constant problem. Coloration difference was notable. Also helps Botryocladia botryoides. Note: contains very little Iron, 0.1% By comparison Ferrion contains 0.4%.
