In your directions for mixing up a batch of KH2P04 equivalent to Seachem Phosphorous, you say to add 3/4 tsp of KH2P04 to 500 ml of distilled water.

I read in a sticky on the Tom Barr forum that Greg Watson's advice for dosing a 60-80 gallon tank with the DI method is to add +/- 3/16 tsp of KH2PO4 3 times a week.
Hi Mike

You're welcome.

Don't confuse this dosing plan with EI, PPS, PPS-Pro, etc. It is a separate dosing plan altogether different that Seachem has provided using their ferts. I just used the online calculators to use dry ferts for their liquid ferts in the Using – Mixing Dry Chemicals for Seachem’s Dosing part of this thread.

These solutions are not based on the EI dosing plan or any other dosing plan. They are solely based on the Seachem Calculator/Chart at their recommended levels that are provided in the very first post as an Excel spread sheet attachment.

This is a lean dosing plan and you can adjust it as needed.

Seachem's Flourish is basically a micronutrient fert with a small amount of macro ferts mixed in. I'm sure that you meant to say Flourish Phosphorus instead.

Have I got your question answered?
