Thanks buddy! Knew there was another that it said u could swap for HH! Is it better to use one per feed and alternate or do them both 1/2&1/2 for what’s it says is HH amount on feed schedule? And my slf100will be here Monday to use with next feed!If your wanting to supplement the HH, tritons trawl is the one. Aphrodites extraction is carbon, it makes a major difference on the trich development... I've also tried the Kraken. It really does make for stiff branches, but if used too much, you can see some bizarre caylx formations.
