CRS and ferts

inthepacific · Yesterday, 04:36 AM

i was just wondering if anyone keeps CRS in a heavily planted tank that they fertilize. is this a good idea? i could imagine it being really hard. i have some really nice plants that i think need more fertilization but i also want to keep CRS in it eventually. just wondering if this is possible

I keep RCS, CRS, and Choc Neos.
I fertilize with Iron, Phosphorous, Nitrogen, Potassium, Kent Plant Pro, Florish Excel, and Osmote Roottabs

is the GH/ TDS too high for CRS if you're fertilizing or do Marcos such as NPK not raise the gh/ tds?

Dosing with CRS in the tank is fine but the dosage is something to be moderated. EI is probably not going to be ideal as it suggests weekly water changes to reboot the tank while failing to do so increases overall tds and toxicity of the NPK + Micros being dosed.

I do light to moderate fert dosing in my shrimp tanks and honestly lean more towards strong light and CO2 injection than ferts. EI is a catch all dosing regiment but if one pays attention to the needs and uptake of the plants (which in itself requires a fair bit of experience) is likely better to dose only what is needed.

I have started dosing one of my shrimp tanks. 20 gal long with crs cbs kk red pandas and so on.

It holds 15 gallons of water after the the soil was added (akadama). My tank is not heavily planted yet maybe 25% planted. T5no lights 6 hours a day.
Adding .5 ml a week of flourish comp
And .5 ml of leaf zone both weekly.

No death of shrimp or plants yet. Will increase or decrease as the tank ages.

Start low and work your dosing amounts up when you see your plants lacking. I just watch my frogbit to tell me when to add more ferts.

Good luck and keep us posted as there is not a general rule with ferts and more sensitive shrimp.
