Flourish Comp will not harm any fish, invertebrates or plants if dosed once or twice weekly at the amount on the label; I do this. The plants will assimilate the metals like copper, both as nutrients and then even if more is present they can take them up as toxins. Another advantage of live plants.

I had DIY co2, but that batch stopped while i was away, and i honestly prefer not using c02, but i enjoyed the results when i used it.. so i may make a batch tomorrow.
This was part of the algae issue, a big part. You really need to give us all the data when asking questions.

I hinted at this previously, but now can confirm it as probable. The CO2 was suddenly lacking, the plants can't use all that light--remember, plants will only photosynthesize if everything is availabe, and once something is no longer sufficient (the "limiting factor" to growth) they stop--so algae had the advantage. Now, I'm not suggesting CO2 be added, again with fish this will naturally be present. Up to you.

Do i need to use fert tablets on top of water fertilizer?
No. The stem plants will be fine on liquid, and the substrate-rooted plants have the Eco-complete plus the liquid. Although i am skeptical of the actual nutritional value in these substrates, there should be something.

I was planning on getting some otto's.... so maybe they will help, i love those little guys.
They will not touch brush or beard algae, or the others mentioned below. The issue is to get the balance restored so this doesn't come back.

I looked it up and it appears to be either fuzz algae or green dust algae... it's gotten 200 times better since i came home, theres only a few spots on the glass left... and the micro sword collects the free floating algae, so i keep vacuuming over those when it collects it up.

the plants are a PITA to get the algae off the leaves... that's the only issue
Any chance of a photo? Green dust algae generally just covers the glass as a fillm, photo below.

ill try to get a picture... but honestly there isnt hardly any left... and my jelly shrimp have been munching on absolutely everything in my aquarium today.

i hooked co2 back up.. it's not something i wanted to do... but i heard it helped growth and survivability of plants.. so i added it.. i prefer NOT to use it.. ill stop using it tomorrow... because i have 8 shrimp in there and will have a couple fish as of this weekend.

Algae pics!

remember this is post 50,000 water changes and some cleaning.. so there's little left, but i'm still interested..

also byron i am confused by your statement, you said algae over took the plants because co2 was missing... but then went on to state you wouldnt recommend co2.

will 2 fish and some shrimp provide enough co2 for plants but not enough for algae?

Photos didn't make it. If you have them in a file on your PC as "jpg" files, when you do a post, click "Manage Attachments" down in the "Additional Options" section and then click "Browse" in the pop-up; double click the photo on your PC and it should load.

Two different issues. While you were away the plants were getting adequate (actually more than adequate) light, but insufficient nutrients (partly lack of water change which replenishes the hard minerals, plus the CO2 which was previously being added was stopped). Law of minimum says plants can't photosynthesize, so algae had the advantage.

Now you need to restore a balance. It can be high-tech with CO2 diffusion plus more nutrient fertilization to balance that plus the light; or it can be more low-tech or natural, with CO2 occurring naturally and less nutrient supplementation. Light may have to be adjusted, but you have to achieve a balance. If this is done, then algae will not have the advantage and should not increase. In natural tanks, or any other for that matter, light should always be the limiting factor. If any nutrient is, esp a macro, then the light past the point when the balance is no longer present will allow algae to increase. Algae is not a "plant" as such, and thus it manages differently than plants with respect to this balance.

You allow the waste to build up in the substrate; those of us with natural planted tanks rarely (if ever) touch the substrate. That is your main source of CO2. I have a spare 20g tank that i keep running for new fish QT, it is planted with cuttings and runner swords from the other tanks. No fish usually, some snails. I add Flourish twice weekly same as all the other tanks. The plants are not as fast growing in this tank, but they remain alive for months. Now and then I have dug into the substrate during the weekly water change just for interest, and it is amazing how much organics are built up, even without fish or fish food entering the tank.

the pictures are showing up for me thats weird..

however at this stage you cant hardly see any algae.. there is some hair algae i found... but now its just fuzz on the micro swords up front and a little on the wisteria and some on the rocks... but the shrimp are going crazy i came home from work and turned my light on and was amazed at how much the shrimp have eaten... they are cleaning everything.

i understand now about what you meant, i took out the CO2 and i'm going to dose flourish twice a week and light 6-8 hours a day, 8 hours a day was working before i left, so i dont see why it wouldnt now. i think i made a mistake and set it for 10 a day while i was gone.

thanks for the advice

You're welcome. But on the duration, monitor it carefully. If memory serves me correctly, you were adding CO2 previously, so it may have balanced with 8 hours. Without CO2, you may have to reduce this. I would suggest that if after maybe 3 weeks there is no increase in algae, increase the light if you would prefer a longer photoperiod. But if algae begins to increase, cut it back. You can go back to six hours with no issues for plants.

I went about 3 weeks without co2, then added it 4 days before i left! and no algae was present prior to that. Some of the algae still in the tank looks brown, so i think thats just normal for a new tank, the nasty stuff is basically gone now.

I enjoy coming home and seeing my aquarium lit up and everything inside moving around, so i will just set my timer to come on at odd hours.. so i can see the tank.. and make plants happy and algae not an issue. after work hours so from like 5-11, or 4-12 midnight... will this cause an issue for fish or for plants being at odd hours like that... i assume not since this is an artificial environment after all

As long as the light period is fairly consistent and representative of a day/night cycle. The "day" can be any time you are home to view the tank, but there must be a period of total darkness. The "day" should also be continuous for the benefit of plants and fish. You can read more on the effect of light on fish here:

Things should be fine re the algae with 8 hours light.
