Best time to water change.

[Martin cape]

Hi guys,

When is the best time to do a water change to avoid fluctuating the co2 level and inducing BBA?

I do mine first thing on Saturday morning. Before CO2 starts and before lights on. Basically when the CO2 is at its lowest level anyway.

I do mine at the same time for the same reasons

I do it about 1 hour after the lights are on in the morning typically. If you have BBA issues, you have CO2 issues, and a water change will help by exposing plants to CO2 in the air etc.

One hour of fluctuating CO2 levels/week doesn't trigger a BBA bloom, I do the water changes whenever I have the time. Organic matter build up on the other hand feeds the algae so whenever you have some spare time do a large water change.

Sunday morning. I turn on my CO2 as usual and then the lights about 5-10 minutes before doing the WC so that the fish dont freak out and I can see what Im vaccuuming, trimming, etc
