I have a 10g which has 2 x 13watt 6500k CFL's and I dose 1.3-1.4ml of excel and 0.17-0.2ml of comprehensive daily. The daily dosing of the comprehensive add's up to the recommended weekly dose. I believe that dosing daily is better.
I read up on dry ferts and do you guys think I need some? My tank has
and more in a day or two.
I went from Flourish Comprehensive to dry fertz and there is no difference hands down. It's that much better IMO. If you do I would monitor parameters until you find that balance. Don't blindly follow a calculator and wonder why you have a tank full of hair algae lol. Really, try it. It's like the difference between a HD tv and the old picture tube style. I'll never watch a CRT again!
I'm not really looking to replace my comprehensive, atleast not until I run out of it.
What I'm asking is if there is anything I should add to what I currently dose?
That would depend on what your water parameters are. Nitrate and phosphate in particular. Iron would be nice but accurate ones are expensive so most don't use them. I found a severe nitrogen deficiency as well as iron when I used it. Nitrates running 0?
My nitrates are reading below 0.25ppm and I don't have a phosphate or Iron test kit. All I have now is the API Master Test Kit.
I was pretty heavily planted so my nitrates were 0. I would shoot for up wards of 10ppm. I could never attain that with flourish. The premixed ferts are simply too dilute. You may be noticing yellowing, transparency or overall little growth in some plants. Does your Riccia grow well and look very Green? The compacta will grow in nearly everything. It flourished in my tank before dry fertz. Anyway, check out the water parameters for happy plants. Primarily nitrates and phosphate.
flourish comprehensive isn't really that comprehensive TBH. It only contains a few trace nutrients...so you have to get the full line including flourish trace, phosphorus, nitrogen, and potassium or get dry nitrogen, potassium and phosphorus. IIRC correctly the dry ferts are: KNO3, and KH2PO4. K2SO4 you may get just in case you see potassium deficiency without it. iron chelate or flourish iron is also optional.
i don't know if we're allowed to post links to other forums, but this post:
discusses EI fertilizing which will be preferable for you since your tank is small and it will be easy to do 50% water changes every week. if you are lazy like me or just can't do 50% water changes you can follow flourish's dosing guide:
I would recommend the latter, rather than the former. A pre-mix will not allow for full customization, which will allow for more control with dosing.
Also, as I previously mentioned, you may want to look into purchasing a GH booster, depending on your water chemistry. If you intend to use RO water, or if your tap water is particularly soft,y ou will want to remineralize it.
Buy individual ferts. If you want, you can always mix up your own dosing solution later to make things easier.
It's so cheap and easy once you get going you won't mind at all.
With Excel, pick the EI dosing for your tank size and divide by 3. Dose that and monitor your growth and algae. Increase or decrease as needed.
