Question Please check my numbers and guide me, not looking like before...

Hello there, I posted this in another thread, but I think it may be good to have its own.

this is a 7 yr old, custom made 30 gal tank.


how can I make it back to what it was before? As simple as it was before.
What are my fert. target numbers?
where do I find good reading to learn this right?(I've been reading in the forum, but I need something more like "for dummies")

It was all good until I changed lights and got 3 spotted puffers.
Everything was rolling just fine with 2.5 ml a Week of flourish comp. and 2.5ml of excel 2 times a week. No CO2. It was fine, just like this:



Then after I was sold T5s and the puffers, plants started collapsing... even common hygrophila difformis and hygrophila corymbosa, which were my most hardier and quick growing plants... wait, even duckweed was jeopardized!

Light is GLO fixture 2 x 24" 24watt T5 HO, 17" from the substrate and 4" from the water level. As seen in the picture:



Timer does 2 light cycles of 4 hrs with a 3hr brake in between.

The store people sold me fertilizers that I'm not familiar with so I started adding after the weekly 7.5 water change and plant trimming:

5ml Flourish Comprehensive Supplement
3ml Phosphorus
6ml Potassium
7ml Nitrogen
3/4 tsp Equilibrium

They told me to use more nitrogen, but I though to increase dosage slowly. They also want me to fertilize twice a week.

I make 2.5gal batches of new water with:

1/4 tsp tetra aqua aquasafe tap water cond.
1/4 tsp seachem solid alkaline buffer
1/3 of 1/4 tsp seachem solid acid buffer

this is the water in my area:



CO2 is pressurized with a solenoid that goes with the light, 5 bubbles per second and goes into the Fluval 204 intake (has a surface skimmer)

Substrate: 7yr old Caribsea Floramax for Planted Aquarium or ECO COMPLETE (don't remember) and some fluoride and playground sand (from when I had a flounder)

After a huge algae attack and probably cyano its doing better but not like before. Now the tank looks like this:



Numbers right before turning lights up in the morning over night

NO3 7.0 mg/L
GH 100 mg/L
KH 140 mg/L
PH 7.0
PO4 0.2 mg/L

Thank you for your help, I don't want to be slaved to lots of fertilizers, how can I make it back to what it was before? in an effort to reduce light input I made a cheesecloth screen to block some light, today. I like it simple.


Plants:
Hydrocotl verticillata
Hydrocharis dubia
Utricularia sp.
Cryptocorye wendtii tropica
Lobelia
Duckweed
Anubias Barteri (new)

Fish:
1- butterfly loach
1- Hill stream loach
10- Giant coolie loach
3- Spotted puffer
6- Amber tetra
2- forktail rainbow
2- Harlequin tetra
1- Clown plecostomus (as old as the tank)
2- marble hatch
1- Otti

Feed daily with 1 cube of frozen hikori shrimp mornings and 1 cube of frozen bloodworms in the evening.


*By the way, the puffers are cute, but they must go, I want invertebrates back to my tank.

That much light you will bee more fertilizer and a good consistant source of CO2

Could I diminish light by cutting time and or screening it as I did with cheesecloth? How can I tell what is the intensity?

Thank you!

Hoppy has posted how much a layer of window screen lowers the light. 25% for one layer, 40% for two maybe? It works but you are wasting money and energy.

Any reason you cannot just go back to what you had before? Evict the puffers and put the old light back on?

thats a good point!

I dont have the old fixture, it was more than 6 yrs old and was all rusty, but I guess I could use different bulbs, I don't remember what I had either, as it was working, I needn't to pay much attn. to it.

any chance for lower light advice?

I think the light was a coralife 24"

---

I changed media in the fluval 204:
I changed half of the "sponge" for the one i cut myself.
I added Seachem Matrix Biomedia to one of the layers. Made my water cloudy...
its gonna go away with the water change.

About fertilizers.... It can get expensive using flourish.

what about solids like this?
