This thread has kind of changed from a CO2 thread to a fertilizer thread. I’d rather not pick at individual ferts without looking at the whole package first. However, your tap water looks like it has all the Ca and Mg you need. With a low light tank, you shouldn’t need much in the way of ferts. So, can you provide the following:
- Current NO3, PO4, GH, KH, pH and TDS readings and which test kits/devices are used for each?
- What you are dosing (product and quantity) and how often?
- What is your filter setup?
- Cleaning regimen (filter and water change frequency and amount)?
- Circulation: surface rippling and are all plants gently moving from top to bottom?
- What is your water source and do you use a water softener?
Regarding these questions:
In my 29-gal, the only surface agitation that I have is small skimmer, but this has been re-configured to return the water above the waters’ surface, so I would judge it to be good agitation with surface rippling. I’m not sure that I know what you mean by plants melting without agigtation, but good agitation will ensure good gas exchange (which includes the very necessary oxygen) and will not cause CO2 depletion if you factor it in to the dosed amount of CO2.
Sorry for the derail, Deanna. I've upped everything this past 2 days, sort of a low ei dosing. Plants continue to show improvement so far, so that's about 4-5 straight days of improvement. Waiting to see how far it goes. Been doing more water changes as well.
These are my previous levels up until 2 days ago:
K=don't know but dosed daily just over 1ppm
Traces=Tropica Premium 1 squirt daily (2mL)
Fe=0.04-0.05ppm DTPA daily
Tests were performed on API liquid test kits.
PH=7.2, KH=5, GH=9, P and N listed above were also on API
These are the new levels I started yesterday...
Traces= Daily 2mL Tropica Premium
Fe=0.08ppm DTPA from Leaf Zone daily (it also adds 2ppm K)
So an overall increase in everything including Fe but not the rest of the traces.
Using city tap water, no softner, treated with Prime.
Ferts are Flourish Nitrogen, Phosphorus, Potassium, Tropica Premium, API Leaf Zone
Tank 38 gal, Filter 2x Aquaclear 200 HOB both filled with sponges. Current is quite strong and all plants are gently moving. Water filled to the top and I get good ripples. Filter media are never cleaned (they never get dirty or clog up). I only clean the intake sponges every week or two.
w/c was done quite a bit this week but I kept my levels up through dosing. Will be doing 20% weekly from now on.
Do you think the new levels are too high? Since the plants are still showing improvement daily, should I keep this level up or naturally let them drop to more realistic levels for lower light, ex 15-20 nitrates, 1-2ppm P?
It's the fish I'm worried about, that's why I don't want to dose too high.
The reason I increased dosage is because on my 3 gal low tech I dose a lot without any worries (no fish) and the plants are not pale. On this tank I dose Fe at 0.16ppm every other day. Weekly dose N=40 to 50, P=3 to 4, K=50+ (100% weekly w/c).
That sounds interesting. I like how you modded the skimmer. By melting, I meant having the ph drop too low at night if I don't provide enough surface disturbance. But I think it should work out on the 3 gal. I have an Aquaclear Mini on that one. There's no fish in this tank so I want to experiment with high co2/light. But first I have to learn how to balance my other tank hahaha.
I really appreciate the help you've given me on this forum, Deanna. Thank you.
