Not sure what's going on. Tank is fairly new. Light is medium to high, 7-8 hours a day. Tank is lightly planted at the moment. I perform 20-25% water changes weekly. I just started using excel and I does Flourish once a week. What should I test for?

I think you have too much light and not enough plants. I'd back down to 5-6 hours of light (even if you add more plants), reduce brightness, or add floaters. Also, I'd consider adding a few stems plants in there

New tanks / pants need time to adjust to water parameters and operate most efficiently. Once you have enough plants in there and growth is going well, then you could up the photoperiod.

Pretty much what @natemcnutty stated.

You can absolutely not start a tank with almost no plant and have good light running for 7-8 hours a day. It's possible to do it with a shorter light period and using every thing at your disposal to make up for the lack of a bio-filter and growing plants. Which would include massive water changes, using carbon/purigen, seeding the feeding from the getgo and even then it would be tough with that amount of slow growing plants.

Thanks for the input! I'll look for some floaters and add more plants. It has a bit more green. Unfortunately, my plant order was delayed by the post office and a lot of them didn't make it.

Here's a pic of the full tank. I'll go for more plants tomorrow! I lowered my photo period to 6 hours. 3hrs/3hrs rest/3hrs.

That sounds perfect. Let us know how it goes for you! Always curious how quickly you start to really see the difference

Seems like my algae is getting worse! I added a lot more plants and lowered my photoperiod to 5 hours. Hasn't helped. Any recommendations?

What light are you using and what size tank? The plants you have may not require the amount of light you are providing.

Just a noob

Beamswork 1W 6500k on a 40G breeder. I think it puts me in the medium category. Would CO2 help control algae?

The co2 will sort of help, by this I mean it will help the plants grow faster. The best way to control or rid the tank of most algae is to get the plants growing well and out compete the algae. You will never get rid of it all as there's not a planted tank out there that's algae free. Your plant mass is still really low and imo most of the algae you have (dust algae) is mainly due to, to much light. Floaters as mentioned before will help diffuse the light or you can look into hacking in a cheap dimmer to the light you have.

Where are you at with your regulator build?

I looked into floaters, but I have a HOB filter and the person I was going to get them from told me that they wouldn't do well with the surface agitation.

I bought two regulators, but I haven't tested any of them. I'm currently bidding on a swagelock needle valve to complete the Matheson build and test it.

I think I found a solution. I had the light directly over the tank. I was able to tie it temporarily to the hood and raise it about 4 inches.

Raising it is definitely another way to go, and on a 40b, you'll actually get better coverage due to the angle on the lenses.

As for the floaters, if you want them, you can use airline tubing and a couple of auction cups to corral them and keep them from going under the outflow.

Lastly, lots of stems are great for a new tank while it establishes. I love using L. Sessiflora for that because of how well it can grow in all conditions.

The algae on the glass behind the heater is probably green dust algae. If you remove it by wiping it off the glass, with the water level below the level of the algae you can go a long way towards eliminating it. When you scrape the glass, letting the scraped off algae stay in the water, the algae becomes free swimming again, and just colonizes larger areas of the glass (as well as the hardscape and some plants). Or, Plantbrain is recommending bristle nose Plecostomus catfish as a faster, more certain way to get rid of it. They eat all of the GDA they can get to. But, there are some downsides to those fish, too.

One thing you can do is scrape the algae off the glass and suck it into a turkey baster. If you can't remove it it will just keep replicating itself exponentially. They have self cloning lobsters, it's obvious to awesome that a basic minecraft block can make a mess in your tank with lower returns.
