So another week into the protein skimmer and I feel it's definitely bedding in more now .. the things I'd say I've learnt about using it on a freshwater set up ...

1) keep your salt levels up ... i use api fresh water salt

2) use a protein skimmer with a strong oxygen pump ..(it's a pity more don't use finer air injection to make the bubbles more of a mist - not as necessary in marine I guess)

3) don't expect huge volumes of output if you're organics are low

4) bedding in and tuning takes patience .. possibly even more than in marine .. get it close to bubbles just touching near top and make small adjustments and leave for a day to see the outcome until it's right

5) putting your hands in the tank etc will cause the skimmate to collapse for a bit so just leave it.. don't be tempted to adjust it if your skimmate is reduced after you've been doing maintenance

6)if you're using a biopellets nitrate filter .. put in the same compartment in sump so it can hopefully remove as much of the denitrifying bacteria cast off as possible

7) personally I wouldn't run a nitrate filter or a protein skimmer until you're tank is fully cycled .. clearing out ammonia and nitrites is the first priority

8) protein skimmers are great for oxygenation so I have mine before the main bio chamber of nitrifying bacteria

9) turn off if you're putting in a treatment

My tap nitrates are 20ppm after a full cycle and 1x30% water change a week my numbers are currently

0.00 ammonium
0.00 nitrite
0.12 nitrate

Fish tank size is 400l plus 80l sump with about 36" of fish in it at the moment (17 fish)

I did more research on BioDigest, and Prodibio claims it contains multiple strains of bacteria, including those responsible for converting organics into ammonia, ammonia to nitrite, nitrite to nitrate, and nitrate to nitrogen. It also has bacteria the reduces phosphates.

Since BioDigest contains so many bacteria strains, it can be used to cycle a tank, and introduce nitrate and phosphate reducing bacteria at the same time. I may use this over Stability for the next tank I set up.

Foiled again, I will be set back a while, as the 10 watt 660nm led chips, are Not 660nm. They are closer to 630nm. Well at least I can get money back.
This is the 3rd time, my lights from suppliers are miss matched.
I still have some 660nm red 3 watt chips, so it's back to watching silicone dry.
