The Opae ula shrimp Forum and online store

I’m off to buy some plant fertiliser with extra iron to experiment... this is in a separate tank with NO shrimp in it... just macro algae with no light on top, it just gets external light from my tanks either side of it.

I've been using Envy in the last two weeks. Purple tech has been maybe 2-3 months. Stopped using purple tech and will continue to use envy. Both were purchased at the LFS.

I purchase this one last night, I haven’t used it yet though.

After the last 50% water change just got to get the Nitrite down. I've some Prodibio BioDigest in the post not shure wether to do another water change then add it or just add it without a water change the Algae seems to be growing so get the Nitrite down and I'll add a couple of Zebra Nerite Snails and tell them to clean up the front glass

Yeah stop dosing Ammonia now, do a large water change and add a vial of biodigest and just observe for a few days and take some measurements as this should speed up the process. Failing that you can just continue to do large water changes until your Nitrites disappear and the cycle completes.

As long as you have zero Ammonia and Nitrites and very very low Nitrates it’s safe to add shrimp.

Hi, one jar has Chaetomorpha Algae , the other jar is an Infusoria and Daphnia culture

24-3-18 75* F
SG = 0.010
TDS = 787
PH = 7.4
Ammonia = 0 ppm
Nitrite = 0.25 ppm
Nitrate = 0 ppm

Nitrite is coming down then by the looks of things?

Awesome and very informative thread. Great job!
