I have a Victron 75/15 charge controller with 200w of solar and a pair of Interstate 31TMXU which are Crown 31DC130 batteries. Here are a couple of links to literature on these Crown batteries. Cro...

On Bulk, suspect the same voltage as Absorb would serve you well. Amp hours would be best if coming in at between the mentioned 10 - 20% range of your batteries rating. So 13-26Amps range, if you have settings to control amp values. I'd probably start 17-18Amps, and see how that works. Bump up or down, based upon your usage and what you're seeing on recharge times. If the batteries are not outgassing too much, then bump them up to the 26Amps and see how things go. (The higher the Amps, the faster the Bulk will finish and get you into the Absorb mode. With solar, faster is better, as you never know when clouds may come in:)!).
Be interested to have you share your experiences with the Crown. Some reading reveals positive, and I believe one member on this forum had a 'It's OK.' comment about a Grp 31 Crown he had bought. The more info actual users share, the more we will all learn about Crown's. (I looked closely at the AGM's, but due to some assistance on replacement costs, retained Lifeline's. And no complaints on Lifeline's from my viewpoint. Good company, backs their products, and helps their customers...).
Best to you,
