UPDATE - Winning Algae War, but Still Cloudy Days - Also, Thoughts on Fertilizer
Algae Killed by Less Light
I think I posted above that I cut the light back to 5 hours per day. I have it on for 5 hours at 100% intensity for all spectrums except blue and it is at 43%. Still not sure why blue should be less, but that seems to be a pattern, so I'll follow it.
Anyway, I don't like that it doesn't come on until 4pm, but the algae has dropped WAY back. My red original red plants- alternanthera reineckii rosanervig (I think) are looking much better- they were really covered in algae, but the leaves are more normal now. It has gone away from the insides of the bushes of wisteria and water sprite, and is no longer topping my hydrocotyle verticulata either.
So, my theory of having enough light and fertilizer to allow the plants to out-do the algae didn't work- or it didn't work in the period of time I gave it (about 2 months I think). I like not having so much algae, so I'll have to figure out how to do the lighting to compromise with my desire to always be able to look in and see them with having the right time/intensity for the plants healthy growth.
I may do something like what
@noahm is doing where it balances light between the 2. The back half get light for a time, then the front half, then both. We'll see. I want to get a whole week with the new pattern before changing.
Fertilizer- Is EI the Best Way to Go?
I also stopped fertilizing this week. I was worried that with less light, the plants would need even less and I don't know what is causing the cloudiness, so I figured let's cut the fertilizer out for a week to see what happens.
Well, the plants are still growing at a tremendous pace. I had a big pile of trimmings in my bucket again yesterday after pruning. I'm very happy with the growth- these are healthy plants.
I do have tabs in the substrate, so I'm sure that's helping with the growth. I did a lot of reading about EI method of fertilization and it is a really good way to go, but honestly, I don't think I have touchy enough plants to require it. Pretty much all the plants I have are in the easy to medium category for maintenance and I do have CO2 going.
I'm going to finish out the week without fertilizing (Wednesday starts a new week of the cycle). I'll start back again on Thursday, but I'm going to do some more reading on other methods. Maybe I'll cut back on the dose I use for the EI method and see what happens. I don't know. I guess if I really want to see what'll happen I should stop the fertilization for 3 weeks and see how the plants do longer term. I might do this later, but don't want to do it while i'm still working on...or waiting on this cloudiness to drift away.
Cloudy Water
The water is still cloudy. I did some vacuuming again yesterday and also changed out 20 gallons of water. It had ZERO effect on the level of cloudiness. I think it's some kind of bacterial bloom. The fish are all fine- hungry and active as ever, and the plants are growing like crazy, so it doesn't seem to have a negative effect on the inhabitants- just the observers...
I have been thinking about opening up the filter and replacing some of the sponge that I added in extra- it was a cross between sponge and floss- maybe I'll put some actual floss in there instead and see if it makes a difference. I might do that Wednesday when I change the water. I have tons of bio media in there, and this sponge/floss is just around the outside of the sponges that come with the filter, so I feel confident that I won't disrupt the biological filtration. We'll see how it looks Wednesday.
Anyway, even with the cloudiness, I really enjoy watching these guys swim around. I love my hatchet fish taking care of the surface, the angelfishies continue to grow and are developing more and more colors and patterns, and the ember, green fire, neon, glowlight and glofish tetras are all zipping around doing their thing.
Oh, also, my raphael is out and about sometimes! I see him FAR more than I did the first one. I'm grateful for that. Maybe he wants to make sure I know he's alive so I don't accidentally throw him out
- good move on his part.
