I have a 60liter reservoir of nutes that I mix once a week and replace the existing reservoir with. On about day 4 of it being there I notice a lot of algae present in the reservoir. I have and air pump with air stones to keep the water airated and it is deprived of light. I also noticed the ph rose from 5.8 to 6.28 over the 4 days since mixing. Fixed that problem tho.
Any one have a recommendation on how to prevent the algae from forming ?

Is the algaeside detrimental to the plants at all ? The only possible light entry is in the form of the clear 5mm air tuning going in otherwise there’s nothing. But there’s a ton of algae

Algae will grow in light and is green. Cynobateria is also green and will look like pea soup. Diatoms are brown and will grow even with no light and feed on silicates for the most part.

First are you running a live system like hydrogaurd or sterile system?... or neither?

No idea what a hydro guard or sterile system is. Just mix nutes once a week and have an air pump with two stones to keep it airated and moving. Algae is brown tho. If that accounts for anything. Last week when it was bad I used molasses in the mix. This week I’ve left that out so gona see if there’s any change

Do not put molasses in dwc or any organics for that matter. Sounds like diatoms they are harmless but messy.

I would do some reading on beneficial bacteria or sterile systems and choose one. Running without anything is usually a disaster waiting to happen.
