Hi garuf,just an idea as you know I run everyhing at it's highest without harming fish/shrimps why not hit it with high co2 and higher nutrients,maybe what the hc need,like a kick start.Garuf said:I hope so, John. I'm not in the mood to give up don't worry.
Cegs recent poor co2 comment made me a little paranoid, however. So I've winged in a second drop checker so I can see what the actual level is. I'm dosing EI recommended for 10gallons which might be another reason but in all fairness it really should be plenty.
Garuf said:I'll hit it with the big guns once I know I won't get algae I think.
Garuf said:Please don't tell me after all this time I've not understood it properly.
Haha, I'm dosing already! I'm thinking after 3 weeks I'll up my dosing. That way I've got higher biomass and the plants will all be adapted to underwater life and as such can take higher amounts of ferts from the water rather than having them accessible to algae.
This is what Ceg has always said with the "feeding the monster" analogy.
Please don't tell me after all this time I've not understood it properly.
On the other hand new tanks are susceptible to algae due to bacterial instability so there is no point dosing more than the EI values unless you see some specific deficiency. Adding more only feeds whatever algae forms so more isn't always better. If you have poor CO2 or poor flow, or too much light you can easily get algae and then you have a Frankenstein in your tank. This is one reason why people blame nutrients for algae - they induce it for some reason and it only gets worse as they feed.
Try severely limiting your light for the first couple of months and you can dose whatever you want. Massive flow, multiple water changes and Co2 will do the trick but the light is the real problem... Even 24 watts over a 15 gallon is a lot of light, especially if you have reflectors.
Well, I'd round down and dose 1/2 the quantities of the 20G. That should still be plenty. Just dose every other day. 3 times a week macros and twice micros. One doesn't need to go overboard or worry too much about micros. I do it to prove a point, but unless your other conditions such as flow/CO2 are perfect, you'll just wind up feeding the monster.
Top tips would be daily 50% water changes for the first 2-3 weeks.
CO2 at 30ppm, dose regular qtys. 6 hour photoperiod, half lighting.
