Excel and Dry Start

I have a dry start 10G with HC and 2x 20w spiral CFLs. When I flood the tank I don't want my HC to melt but I don't want to use CO2. Is it possible to overdose on excel to prevent melting? If so, how much more than the recommended dosage? Thanks!

twice the amount? two 20 watt CFLs for a 10G seems like a lot. I had two 20 watt CFLs over my 40B and i had algae like a mofo. you should probably get 13 watt CFLs instead.

I wanted to do 20w CFLs because there was a guy who had 2x 23w CFLs and no CO2 but his HC grew really well. I figure that 26w wouldn't be enough to grow HC, but 40w can, and the 6w difference from that guy's tank would require less CO2.

P.S.: Do you know if I can overdose on excel to prevent melting once I flood the tank?

Leaves that have grown in the air are different than leaves grown under water. The plant is simply adjusting to growing underwater when it sheds the air grown leaves.

I strongly suggest you swap those 20-watt bulbs for 13-watts; trust me. I had plenty of CO2 and ferts and still has issues with algae with those lights until I stepped it down. If you had a lot of biomass and CO2 I would say it'd be worth a shot, but I guarantee you'll have an nice algae bloom in no time with just a little HC and nothing else. Just trying to help

As for the excel-I'd imagine it would be difficult to 'overdose' the tank without any livestock in it. I'd say a 2x initial dose and 3x daily dose with daily 50% water changes for at least a week is in order.

Lol Overgrowth, I'm tellin you man, those 20 watt bulbs are going to give you a massive outbreak of algae, especially in a 10G.

Would you have algae problems in emersed growth with the water level below the substrate?

No. I only saw alage on my substrate when the water level was too high during the dry start; formed on the glass at the substrate level as well.

SeaChem has excellent customer service. Call them up and ask to speak to a planted tank specialist.

Thanks man, you were the only person to answer my initial question. Not that the other posts weren't helpful, it's just that one question I wanted to know when I flood the tank I will dose excel everyday like you suggested with no livestock in it. However, what would be the purpose of the water changes?

im in the same situation as you. what is your substrate? im doing a DSM on dirt in a 10 gallon. DHG and HC. Reading the diana walsted thing i noticed she used HC and then filled her tank with no ill affects at all. I was just planning on following this and dosing excel or starting up a diy co2 if i HAVE to. Otherwise i wasnt going to touch it. I also tested this by pulling a stem out and planting it in a dirt tank. I saw no transition affect, nor did it melt. I feel like if the DSM is kept in high enough humidity and wet enough that the transition affect is minimal. at least thats what ive noticed.
