Interesting problem in classroom tank

[Js.Aqua.Project]

Any kind of intentional macro/micro algae growth will help with the pH.

I agree, and would recommend you start, with a skimmer & CO2 reactor.

Try reaching out to any LFS in your area and some of the bigger companies. Occasionally (as a school) you get lucky and someone will donate something to help you out. It is also a good idea to touch base with your local reef club (if you have one) as they can be helpful and tend to have extra equipment on hand they might donate.

I sponsor the marine biology club at my high school and we have a similar issue, but luckily our pH stays within range throughout the day. Luckily, I have a door to the outside the works and is the main entrance to my classroom so it is open frequently to let in fresh air.

I hooked up my DIY CO2 Scrubber in the morning on October 20. Here's my "after" results.

How big is your tank, and how much soda lime are you using at a time? And I would be very interested to know how often you have to replace it.

I believe Harbor Freight or Northern Tool.

Thanks, the kids have been working hard. They wanted to learn about aquaculture so I said the best way to learn is by doing and now this is where we are.

180g plus 40g breeder sump. I filled a 20oz Gatorade all the way up about a week ago now, and about half of it is purple now.
